Trying to load .bashrc config file locally - cygwin

I'd like to create a .bashrc file in my Git Repo which should then be shared with other devs. The goals here is to add project-based aliases for every dev.
For instance when using node.js tools, a lot of them check the current directory for configuration files (ex: grunt looks for Gruntfile.js, JSHint looks for .jshintrc, npm for package.json).
I want Cygwin to look after .bashrc in the local directory.
I don't want to change the $HOME variable since it would allow me to only work on one project at a time.

I fixed the issue with aliasas
Run touch .bash_profile command
change file to contain all aliases. Example:
file .bash_profile
alias ga='git add --all .'
alias gp='git push'
Every time you open the Bash, type . .bash_profile to reload the file and therefore register the aliases.

Copying shell file to path

I'm new to WSL and Linux, but I'm trying to follow installation instructions for rhasspy (https://rhasspy.readthedocs.io/en/latest/installation/#windows-subsystem-for-linux-wsl). I have run the make install command successfully and the next step says I should copy rhasspy somewhere in my path but I can't quite figure out what copying to path means.
When installation is finished, copy rhasspy.sh somewhere in your PATH and rename it to rhasspy.
I added it to path but nothing changed so I was wondering if there is something I'm doing wrong. Right now when I run rhasspy on wsl it says rhasspy.sh: command not found. Any help would be really appreciated!
What it says is, put it in some place where the system will look for it when you type its name without full path in the shell.
There is an environment variable PATH that contains all those locations, separated by a :. (Check out echo $PATH.)
So, the author of these instructions leaves it up to you whether...
You want to copy the file to a location of your choice that is already in the PATH, such as /usr/local/bin or ~/bin.
Usually ~/bin is a good choice because it is per-user and doesn't pollute the system.
(Note that the directory ~/bin is added to the PATH by your .profile file only if it exists, so if you don't have this directory yet and create it now, you need to start a new login shell or run . ~/.profile1 before you can use it.)
- OR -
You want to create a new directory specifically for this application (say for example ~/opt/rhasspy) and append that directory to the PATH variable.
This can be done by adding the line export PATH=$PATH:~/opt/rhasspy to your ~/.profile file. Then, start a new login shell or reload the file using . ~/.profile1 for the changes to take effect.
If the directory in which this file is currently located is OK for you to keep permanently, then you can also just add that directory to the PATH instead of creating a new one.
Note: The PATH always contains directory paths in which the shell will look for executable files. It does not contain the actual file paths!
1: Yes, technically it is "cleaner" to log into a new shell or to run that one export statement manually instead of using . ~/.profile because the latter will apply things a second time that were already done before, so for example it can end up with the same directory in the PATH multiple times in the current session. In most cases that is fine though.
PATH is an environment variable. When you launch env, you see the list of known environment variables on your system.
In order to add something to your PATH variable, you need to take the variable, add the mentioned directory (preceeded by a semi-colon, most probably, as a separator) and store this again as the PATH variable. This can be done as follows (own example):
export PATH=$PATH:/home/this_user
the "PATH" it is referring to in linux is just inside the folder called /usr/bin. when you type a command into the terminal it looks for a program with that name inside the location. im not sure if this is the PATH you are looking for but hope it helps

Autorun Bash Script after Login to Sync Git Repos

I have already a gitupdate.sh that I found on the internet.
My problem now is how to make the script run automatically every time I log into my Ubuntu 14.04 computer.
I have tried adding this line to .bashrc
sh '/path/to/git/repo/gitupdate.sh'
The problem here is the script is executed not in the context or path of the repo thus the script runs in a folder that is not initialized with git. (I don't actually know what folder bashrc run on)
What want to do is that the update script to be run by Ubuntu in the context of the path so the script will not fail. And also show the running script in a Terminal window that will not automatically close.
And the ultimate goal, is to be able automatically upon login, that git cloned repos to be synced with the public repos.
Try
(cd repo && bash /path/to/gitupdate.sh)
Just open the gitupdate.sh and at the beginning of the file just add the command to go to the selected direcotry. For example:
cd /var/test

How to set up shell alias so I can change directories

I use bower and grunt in my workflow, and I wanted to install bower at the same time as grunt and pull down all my bower dependencies. So I created a package.json file that has a script attached on postinstall, which I also pass my github project repo, and dropped my post_install.sh into /root/bin.
{ // snippet of package.json
...
"scripts": {
"postinstall": "bin\\post_install.sh https://github.com/blah/blah.git
},
...
}
so running npm install would run post_install.sh, which runs
#!/bin/bash
node_modules/.bin/bower install
grunt setup
git init
git add .
git commit -m "Initial commit of project artifacts"
git remote add origin $1
git push -u origin master
This only works if I set git bash to open in my project directory. So I've been trying to figure out how to switch directories from where git bash opens at /htdocs to /htdocs/myproject using an alias. I read up on how to set this I thought, but I can't figure out how to invoke this file... incidentally also tried putting it in another .sh file to see if that worked.
#!.bashrc
alias projDir='cd /onloadsolutions'
What am I doing wrong that the alias above in /bin/.bashrc won't execute in my post_install.sh when dropped above "grunt setup"?
Dropping this into post_install.sh
echo "script running has basename `basename $0`, dirname `dirname $0`"
echo "present working directory is `pwd`"
gives a basename of D:/htdocs/onloadsolutions/bin/post_install.sh, but my present working directory is /d/htdocs, which when the bower and git commands run they do it in the wrong directory.
Not 100% sure what you mean but I am guessing when you open bash you want to
be able to type a command to take you to your project
then type npm install and have it pull down all your dependencies
Try editing your .bashrc file (this should be in your home directory, not in the /bin folder) to access this you can use something like
nano ~/.bashrc
(~/ is a shortcut to your home directory)
and look in it for any existing alias commands or add yours down the bottom.
then after opening another bash session (.bashrc only runs when you first start terminal) you should be able to see your current aliases by typing "alias"
you can launch the alias you mentioned above by typeing "projDir" into the console. It would be much better to add the full path in your alias i.e.
alias projDir='cd /var/www/onloadsolutions'
then you can call it from anywhere. Otherwise you might end up in a different folder than you expect.
UPDATE
See comments below.
Put cd $2 in the second to top line of the post_install.sh file and add a second parameter to the package.json file that calls it.

.bashrc in Cygwin 1.7

I'm running Cygwin 1.7.17 on Windows Server 2012. My user account is "Administrator". Where should I put a .bashrc file for the Cygwin bash to pick it up?
I've tried the "c:\users\Administrator" folder, which seems to be the HOME in Cygwin 1.7. Tryed c:\cygwin\home\Administrator also.
Start a shell instance and run the command echo $HOME to see what your home path is set to. That's where all your user config files will be read from. It might not be one of the paths you tried.
Once you know where it is, just copy the template .bash_profile and .bashrc files from the /etc/skel folder to get you started.
If you don't like the path that's currently being used as your home, you can change it by editing /etc/passwd. Here's more info on that... Safely change home directory

Managing user configuration files across multiple computers

I commonly work on multiple computers. I have various configuration files, eg, .bashrc, .gitconfig, .irbrc, .vimrc and configuration folders, eg, .vim/ that contain valuable customizations.
Sometimes I want small variations in configuration between the different computers.
I want to use version control to manage these different files.
do others use version control to manage their configuration files?
what are some hints that might make this easier?
what's the most elegant way of dealing with variations between the computers?
I'm comfortable with git; any other suggestions?
I keep a folder at ~/config/ which is a bzr repository. I push/pull the repository between my various computers to sync it up. I have an install script which I use to make symlinks to my home directory:
#! /bin/sh
# link all files to the home directory, asking about overwrites
cd `dirname $0`
SCRIPT_DIR=`pwd`
SCRIPT_NAME=`basename $0`
FILES=`bzr ls --versioned --non-recursive`
cd $HOME
for FILE in $FILES; do
ln --symbolic --interactive $SCRIPT_DIR/$FILE
done
rm $TARGET_DIR/$SCRIPT_NAME
If you want to use git instead of bzr, you can instead use:
FILES=`git ls-tree --name-only HEAD`
(I had to ask SO to figure that out)
EDIT: I don't actually do this anymore, now I have a dotfiles repo on github, with a nice rake install script that someone else wrote.
At the moment, I use a cloned git repo. To keep things simple, the only file that needs to vary between the different machines is .bashrc. It's nice if there can be just one version of this file that responds differently on different machines. Thus, in my .bashrc:
if [ $(hostname) == 'host1' ]; then
# things to do differently on host1.
elif [ $(hostname) == 'host2' ]; then
# things to do differently on host2.
fi
This obviously has some limitations (such as that a different technique would be required for .vimrc or other config files needing customization), but it works fairly well.
If you use git, you could define an "origin" repo to be the master; and then do a clone on each computer you work. you could use a branch for every computer to have your set of config files.
With CfEngine you can manage config files across machines and do also many more things!
The learning curve is maybe a bit high but worth it if you have to manage/update/maintain a pool of computers running linux regularly.
Easy. Use DropBox for that:
http://www.nixtutor.com/linux/sync-config-files-across-multiple-computers-with-dropbox/
I use slack for a similar situation. slack allows definition of roles/subroles so you can manage files with small variation either through a cloned file or patch. The slack directory is then managed by git in my deployment.
Here are some dotfile managers:
homesick: Based on Ruby
homeshick: Same as first one, but without ruby dependency
dfm: Written in Perl
git with branches for custom computers, with automated sync at login seems like a good solutions to me.
I've used etckeeper for versioning configurations, but I've never actually expanded to user configurations.
This kind of question comes up occasionally, and I've never seen a tool to handle this common use case, so I wrote a script that uses git and symlinks to manage these files.
See http://github.com/bstpierre/dotfiles
It is not perfect. There is currently a bug related to handling directories, and there is no support yet for variations across computers.
Before using any tool of this nature, make sure you have good backups!
I think what you want could be similar to what I've been doing...
Make a directory in home called .host_configs/ . This is version controlled. Or in my case it lives in a special folder on a central computer, I scp it down on any new machine. Inside it make a folder for every host that you want different configurations for. The folder for each host should be named after the short hostname for that machine. So in your git repo you have:
.host_configs/
homecomp1/
girlfriendcomp1/
workcomp1/
workcomp2/
In each host specific folder, put the .vimrc, .irbrc, etc., configuration files for that specific box.
And also, in each host folder make a file called .[SHORT_HOST]_rc. For instance, if your machine is name "sane" have a file named .sane_rc ... This file will contain the lines that would normally be in .bashrc that are unique to that host. For instance, if it's a mac and it needs alias ls='ls -GF' instead of alias ls='ls --color=auto' which works for most nix machines for ls with colors, put that line in the .[SHORT_HOST]_rc for that machine, along with whatever special functions, declarations, etc, that would normally go into the .bashrc or .profile etc. (or .zshrc, .tschrc, as the case may be). So the version controlled ~/.host_configs/ folder looks like:
.host_configs/
homecomp1/
.homecomp1_rc #special shell configs for this hostname
.vimrc #you know the rest
.irbrc
.Xresources
girlfriendcomp1/
.girlfriendcomp1_rc
.vimrc
.bubblebathrc
workcomp1/
.workcomp1_rc
.bashrc
.vimrc
workcomp2/
.workcomp2_rc
.bashrc
.vimrc
I use all the same barebones $HOME/.bashrc (or ~/.tshrc etc) on all of my machines. I just take the basic one that comes with the distro in question and move all of the host-specific configuration into the .host-configs/[SHORT_HOST]/.[SHORT_HOST]_rc file.
Put this at the bottom (of $HOME/.bashrc):
export SHORT_HOST="sane"
for file in `find ~/.host_configs/$SHORT_HOST -name ".*"`
do
ln -s $file `basename $file`
done
source ~/`.$SHORT_HOST`_rc
(Finds all of the dot-files for the host and makes a symlink in home to the~/.host_configs/foo_host folder).
Your dot files are in their normal location but they are symlinked to version control. The above also sources all of the lines in your [$SHORT_HOST]_rc file into .bashrc
You can commit back to git from the ~/.host_configs/ folder whenever you have changes.
That's what it looks like in shell, which is probably all you need, but if you need other features, I would write something that uses the same principles (sourcing an external .rc file into .bashrc and symlinking all the config files to the structured version control folder) in something more versatile/less ugly than shell. So instead of the above in your .bashrc, there could be:
export SHORT_HOST="sane"
ruby ~/import_conf.rb $SHORT_HOST
...and write your import_conf.rb to do more complex conf management, like placing a specific configuration file in some directory besides home, or handling a config folder like .ssh/, .subversion/ etc. That's what I do, it's pretty elegant for me, but there may be better solutions. Dropbox with some creative symlinks is also an excellent idea, though you're relying on a third party, and you need to be in a graphical environment. Also note there are inconsistencies between what you can do with symlinks + dropbox in Linux and shortcuts + dropbox in Windows if you implement something that wants to play with Windows.
Now there is also vcsh
From the README:
vcsh - manage config files in $HOME via fake bare git repositories
[...]
vcsh allows you to have several git repositories, all maintaining their working trees in $HOME without clobbering each other. That, in turn, means you can have one repository per config set (zsh, vim, ssh, etc), picking and choosing which configs you want to use on which machine.
Works perfectly, but may be a bit daunting if you are not an experienced git user.
Most of these answer address sync, but not how to tailor the files for the specific device. filetailor is an open-source Python program for this exact issue. Based on a YAML configuration file, it can make small changes to the files using device-specific variables or using device-specific comments in the files. Then, use another program such as Syncthing or Git to transfer the files.
For example, the following line would be commented out on every device except the one with hostname device1.
alias MYHOME='/home/dev1home/' #{filetailor device1}
Disclaimer: I had this same issue and made filetailor to solve it.
