I am missing my basic unix commands on Yosemite 10.10
Here is my path from ~/.zshrc
export PATH="/Users/tims/.rbenv/shims:/usr/local/bin:/usr/bin:/usr/local/shared/bin:/usr
I will check my ~/.bash_profile
Very strange
$ type -a cd
cd is a shell builtin
cd is /usr/bin/cd

I'am trying to install brew on linux using
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
then adding brew to the path using
test -d ~/.linuxbrew && eval $(~/.linuxbrew/bin/brew shellenv)
test -d /home/linuxbrew/.linuxbrew && eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)
test -r ~/.bash_profile && echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.bash_profile
echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.profile
It works fine on the current opened terminal but when i change the terminal I get
Command 'brew' not found
Any Idea how to fix this?
I found out the answer, it seems that I have to set the environment variable to
export PATH="/home/linuxbrew/.linuxbrew/bin:$PATH"
and not
export PATH="$HOME/.linuxbrew/bin:$PATH"
To permanently update ~/.profile with source, only working on manual input. Also reboot of the whole system won‘t update ~/.profile and i need to update it manual.
Is there a special code style to use it as working code inside a bash/shell script or is this special code not intended to be used in automated scripts?
Need it to automate installation of golang.
In the following code the line "source ~/.profile" won't work, and without any error messages, the rest is working fine:
#!/bin/bash
sudo apt update
sudo apt -y upgrade
cd ~
curl -O https://dl.google.com/go/go1.12.5.linux-amd64.tar.gz
tar xvf go1.12.5.linux-amd64.tar.gz
sudo chown -R root:root ./go
sudo mv go /usr/local
cd ~
sudo rm go1.12.5.linux-amd64.tar.gz
sudo echo "export GOPATH=\$HOME/work" >> ~/.profile
sudo echo "export PATH=\$PATH:/usr/local/go/bin:\$GOPATH/bin" >> ~/.profile
source ~/.profile
Preferred:
Source the script itself rather than running it - then the commands in the script are run in the current shell, including the source ~/.profile.
Alternative (since this replaces the running shell, history, variable values, and other state will be lost. So there should be a very good reason to use this method):
Use exec bash or something similar instead of source ~/.profile - this replaces the currently running Bash with another instance which will itself load the new .profile.
Here is a refactoring which defers the decision to the user and cleans up the script somewhat.
#!/bin/bash
# Put this in a variable so there is only one place to update
tarball='go1.12.5.linux-amd64.tar.gz'
sudo apt update
sudo apt -y upgrade
# cd || why would you?
curl -O "https://dl.google.com/go/$tarball"
tar xvf "$tarball"
sudo chown -R root:root ./go
sudo mv go /usr/local
rm "$tarball"
printf '%s\n' "export GOPATH=\$HOME/work" \
"export PATH=\$PATH:/usr/local/go/bin:\$GOPATH/bin" >> ~/.profile
echo "$0: done. source ~/.profile or exec bash to activate new settings." >&2
In my .bashrc I'm using .sh script for easily configuring newly installed Debian. But while trying to
rm -f ~/.bash_aliases
wget https://raw.githubusercontent.com/.../.bash_aliases
rm -f ~/.bashrc
wget https://raw.githubusercontent.com/.../.bashrc
it's just omitting those line?
File is with permission chmod +x ./script.sh and run by sudo ./script.sh
What could possibly be wrong?
(In final code there is full link, files are being downloaded as .bashrc.1 and .bash_aliases.1)
Don't use sudo unless you have a good reason.
When you run sudo ./script.sh it runs as root, so ~ refers to root's home directory /root instead of your user's home directory.
Just run ./script.sh instead, so that it runs as you and modifies your own home directory.
I installed leiningen on fedora, I followed the instruction:
download the script
Paste the script(via command line) to ~/bin (PATH)
Execute the script
Run lein(I had to did it with sudo) to self-install
but every time I want to run the "lein" command, I have to do it with "sudo".
How can i fix this? or what can i do to fix this?
Note: I installed leiningen at /bin but when i cd ~/bin as the installation guide said i get and error about the folder(not exist).
You installed it in /bin and ran it with sudo to install the lein jars initially, which means they are owned (and probably only readable) by root. You should install the script at ~/bin instead. You can fix it like this:
sudo rm /bin/lein
sudo rm ~/.lein
mkdir ~/bin
cd ~/bin
wget https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein
export PATH="${HOME}/bin:${PATH}"
lein
You should also add ${HOME}/bin to your $PATH. If you are using bash, add this to ~/.bashrc:
export PATH="${HOME}/bin:${PATH}"
You can do that using echo:
echo 'export PATH="${HOME}/bin:${PATH}"' >> ~/.bashrc
anybody is familiar with the etcd project? Or we'd better forget the project when talk about this issue. The issue is
$ build
ln: `gopath/src/github.com/coreos/etcd': cannot overwrite directory
when exec the build shell
and the content is:
#!/bin/sh -e
if [ ! -h gopath/src/github.com/coreos/etcd ]; then
mkdir -p gopath/src/github.com/coreos/
ln -s ../../../.. gopath/src/github.com/coreos/etcd
fi
export GOBIN=${PWD}/bin
export GOPATH=${PWD}/gopath
export GOFMTPATH="./bench ./config ./discovery ./etcd ./error ./http ./log main.go ./metrics ./mod ./server ./store ./tests"
# Don't surprise user by formatting their codes by stealth
if [ "--fmt" = "$1" ]; then
gofmt -s -w -l $GOFMTPATH
fi
go install github.com/coreos/etcd
go install github.com/coreos/etcd/bench
Some addition:
My system is windows 7
I run the shell on git bash.
issue reproduce:
step1: open the git bash
step2: git clone git#github.com:coreos/etcd.git
step3: cd etcd
step4: build
As mentioned in "Git Bash Shell fails to create symbolic links" (since you are using the script in a git bash on Windows 7)
the ln that shipped with msysGit simply tries to copy its arguments, rather than fiddle with links. This is because links only work (sort of) on NTFS filesystems, and the MSYS team didn't want to reimplement ln.
A workaround is to run mklink from Bash.
This also allows you to create either a Symlink or a Junction.
So 'ln' wouldn't work as expected by default, in the old shell that ships with Git for Windows.
Here's solution. Tbh it is a workaround, but since you're on Windows, I don't see another way.
Start a command line, and enter there to the directory with the script. There should be a path gopath/src/github.com/coreos/ (if no such a path, you must create it). Next issue a command
mklink /D "gopath/src/github.com/coreos/etcd" "../../../../"
Next you should edit the build script to delete a lines with creation symlink and a directory. E.g.
#!/bin/sh -e
export GOBIN=${PWD}/bin
export GOPATH=${PWD}/gopath
export GOFMTPATH="./bench ./config ./discovery ./etcd ./error ./http ./log main.go ./metrics ./mod ./server ./store ./tests"
# Don't surprise user by formatting their codes by stealth
if [ "--fmt" = "$1" ]; then
gofmt -s -w -l $GOFMTPATH
fi
go install github.com/coreos/etcd
go install github.com/coreos/etcd/bench
Note, that I am just removed 4 lines of code. Next you run the script, and this should work.
You shouldn't be using git clone and the build sh script. Use the go get command. For example, on Windows 7,
Microsoft Windows [Version 6.1.7601]
C:\>set gopath
GOPATH=C:\gopath
C:\>go version
