I have both Bash on Ubuntu on Windows and Cygwin bash installed on my machine, and both are setup to have the same ~ folder (via /mnt/c/source and /cygdrive/c/source respectively).
When I start Ubuntu's bash prompt via bash --login -i (or just bash --login) from any directory, I get a prompt running from within that directory; however, when I start Cygwin's bash via the same command, the current directory is overridden, and the prompt is always at ~. See the screenshots for a simple example.
My user directory's .bashrc and .bash_profile are of course the same, as both are using the same user directory. I've looked into Cygwin's /etc/bash.bashrc and there doesn't seem to be anything there to change my current directory, and there aren't any other relevant files in /etc.
What could be causing Cygwin's bash to change directory?
you just add a command "cd /dir_you_want" at the bottom of ～/.bashrc in cygwin
I've figured it out, so in case anyone runs into the same issue:
There's one file I neglected to look into, because I didn't know it exists, /etc/profile. In Cygwin, by default it has the following section in it:
# Make sure we start in home unless invoked by CHERE
if [ ! -z "${CHERE_INVOKING}" ]; then
unset CHERE_INVOKING
else
cd "${HOME}" || echo "WARNING: Failed attempt to cd into ${HOME}!"
fi
Disabling that solves the issue of course.
I would like to switch to the bash environment after ssh login. Currently I have to type bash every time and then cd to my working directory.
Where can I add some settings so it will run automatically for me.
There's an environment variable SHELL that is set to the current shell. You can set it to your preferred shell by running
$ export SHELL=/path/to/shell
In order to find the path to your preferred shell just run following command
$ whereis bash
Enter the path returned by whereis command as your shell path.
There's a .profile(ls -al) or bash_profile that you can add your setting there. If you can't find such a file then create one using touch .profile. (I did create this file on OS X.)
Open the .profile in order to edit it using whatever text editors that you want
$ vim .profile
Then change the $HOME environment variable in order to change your default home directory path. Enter below line in opened file
export HOME=/your/path
Save the file

I use phpstorm and it's terminal facility.
In terminal section I typed F:\Projects\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico - so it uses Cygwin as terminal. But it opens it in home folder. Is it possible to open it in different folder? By typing a command or by doing something else.
Because I have a folder called F:\Projects\Local in this folder I have vagrant and I want to open phpstorm, open terminal within php storm and just type vagran up. I don't want to open cgywin again.
thanks
If you just want to open Cygwin with Mintty in the project directory then you can execute the command:
F:\Projects\cygwin64\bin\mintty.exe /bin/env CHERE_INVOKING=1 /bin/bash -l
This will avoid automatically changing to the home directory. See https://code.google.com/p/mintty/wiki/Tips#Starting_in_a_particular_directory for more information on this command.
If you want to use the embedded PhpStorm terminal, then you can modify the Shell path in the terminal settings. Open File > Settings... > Tools > Terminal. Replace the shell path with F:\Projects\cygwin64\bin\env.exe CHERE_INVOKING=1 /bin/bash -l. You may need to restart PhpStorm after this change.
Note: this is assuming that your Cygwin Root Directory is F:\Projects\cygwin64\.
For whome the above way ain't work anymore, like in PhpStorm v. 2016.3. The shell path have to be enclosed in quotes
"C:\Users\MyUser\.babun\cygwin\bin\env.exe" CHERE_INVOKING=1 /bin/zsh.exe
For the PhpStorm that I'am using (v10.0.4) in Windows 10 I use this command works:
D:\tools\.babun\cygwin\bin\env.exe CHERE_INVOKING=1 /bin/bash.exe
I'm using Babun which installs the Cygwin in D:\tools\.babun\cygwin.
I have added HADOOP_INSTALL and it's bin to the PATH variable in my .bash_profile (shown below) and executed it using the command . .bash_profile. I can run the command hadoop version fine but when I close the terminal and run the same command again it gives me error as follows
gsidevas#gsidev-cloudvm ~]$ hadoop version
bash: hadoop: command not found
Current .bash_profile
export HADOOP_INSTALL=/usr/local/hadoop
PATH=$PATH:$HOME/bin:$HADOOP_INSTALL/bin
export PATH
What do I need to do so that this HADOOP_INSTALL and it's bin gets set permanently in my environment?
By default, BASH reads and executes commands in .bash_profile only in login shells. If you're creating a terminal via some X11 or similar software, chances are that terminal is not a login shell by default.
You can achieve this effect for every shell by simply moving the changes you made into your .bashrc file. Please note that this only works properly if your username on the system uses "bash" as its shell and not "sh" since for "sh" the .bashrc file is, by default, ignored.
I am trying to define some aliases in cygwin, but with no success. I am doing so like this at the end of the .bashrc file.
alias foo='pwd'
I have tried to add this line in a .bashrc file in both inside the home folder of cygwin and in the home folder for the Windows user I am on C:\Users\Nuno\. In both cases I have just appended this line to a copy of the /etc/skel/.bashrc file. In either cases, it didn't work.
I had this working before. I had to reinstall Cygwin and ever since it never worked properly again. I have removed all files (or at least think so, when doing the reinstallation). I have also noticed that in the first install (when it was working) cygwin already was creating .bash files in the home folder. Now, it doesn't.
I am on a machine running Windows 7.
EDIT: My cygwin home folder is set to the Windows home folder C:\Users\Nuno\. I have placed what I think is a valid .bashrc file there, but it still doesn't work.
Thanks in advance.
As me_and already explained what's going on I just want to add a workaround should you for whatever reason not be able or willing to remove Windows' HOME environment variable.
Normally the shortcut for Cygwin executes
C:\cygwin\bin\mintty.exe -i /Cygwin-Terminal.ico -
Instead you can create a batchfile with the following content and start that:
#echo off
set HOME=
start C:\cygwin\bin\mintty.exe -i /Cygwin-Terminal.ico -
That will start a a Cygwin windows whose home directory settings are not overridden by a Windows environment variable.
Your .bashrc file will be loaded from wherever Cygwin Bash thinks your home directory is when it starts. You've mentioned in your edit that you've changed your home directory, but not how, so it's possible you've made a mistake there.
Cygwin will load your home directory from one of two places, and if they differ it can cause problems:
The HOME environment variable. This will be picked up from however you launch Cygwin, so normally from Windows itself. You can see what environment variables you have defined by pressing Win+Pause, going to "Advanced system settings", "Environment Variables…". If "HOME" is in either "User variables" or "System variables", delete it – it's unnecessary and only causes problems.
Cygwin's /etc/passwd file (normally C:\Cygwin\etc\passwd from Windows). This will have a number of lines containing details of each user on the system; the seventh : separated field is the home directory. You can tell which user it's looking at by running whoami from a Cygwin bash shell.
If whoami reports nunos, you should have a line in Cygwin's /etc/passwd that looks something like the following:
nunos:unused:1001:513:U-System\nunos:S-1-2-34-567890-123456-7890123-1001:/home/nunos:/bin/bash
It's that /home/nunos that's important; if it's something different you should probably reset it to that, at which point you want to use the .bashrc in Cygwin's /home/nunos/.
You should also be very wary of directories that contain spaces for this. C:\Users\nunos should be fine, but beware in particular C:\Documents and Settings\nunos, which just won't work with Cygwin.
I had the same issue, where the aliases added to ~/.bashrc didn't work.
It seems that, for some reason, the ~/.bashrc was not executed when launching the console.
I stumbled upon a response that fixes the issues
So, you need to create a .bash_profile file. This one seems to be the default script, and put this code in it, to ensure that the .bashrc is executed.
# ~/.bash_profile: executed by bash for login shells.
if [ -e /etc/bash.bashrc ] ; then
source /etc/bash.bashrc
fi
if [ -e ~/.bashrc ] ; then
source ~/.bashrc
fi
That works for me, just make sure that .bash_profile is executable. (chmod +x ~/.bash_profile)
Here's a really quick and dirty way to do it, but it works fine for most things!
Let's say you want to always run 'ls --color' instead of just 'ls'. Instead of messing around with .bashrc stuff, you can create a simple .bat file that essentially bootlegs the original ls command.
Here's what I did:
cd /bin
echo ls2.exe %* --color > lsNew.bat
mv ls.exe ls2.exe
mv lsNew.bat ls.bat
So now, whenever you type in ls from CMD, you actually are calling ls.bat, which in turn calls ls2.exe --color, the original ls command with the --color flag, along with the rest of the arguments, which are nicely passed through %*.
I had the same problem, but I was using ConEmu to run my console. I had to go into settings and change the settings from this :
set CHERE_INVOKING=1 & %ConEmuDrive%\Programs\Cygwin\bin\sh.exe --login -i -new_console:C:"%ConEmuDrive%\Programs\Cygwin\Cygwin.ico"
to this:
set HOME= & set CHERE_INVOKING=1 &
%ConEmuDrive%\Programs\Cygwin\bin\bash.exe --login -i
-new_console:C:"%ConEmuDrive%\Programs\Cygwin\Cygwin.ico"
Then it would work correctly.
It works as explained from cygwin:
Create a file ".profile" in your windows home dir. This will load every time when you start cygwin.
You can edit the file with your alias or you can source the .bashrc.
If you'll source, insert "source .bashrc" and save .bashrc also in your windows home dir.
Now you can start editing the .bashrc.
This is working for me On windows 10 with Cygwin64. Don't worry "kubectl" is just the program that I want to run when I type "k". restart Cygwin terminal after the change.
Smith#NB-Smith-3 ~ echo "alias k=C:/Users/Smith/kube/kubectl" >> $HOME/.bash_profile
changes this file
C:\cygwin64\home\Smith.bash_profile
I had same problem is why the path not is correct, the path correct is: D:\C++\cygwin\home\USER_WINDOWS.bash_profile
