My goal is to execute two commands in a specific folder as ubuntu from outside of it's lxc container.
I've tried a couple of things but I figured this example is the closest I have to working.
If I run
root#host$ lxc exec my-containter -- sudo --login --user ubuntu eval "cd /home/ubuntu/mydir && pwd && whoami && env && npm install && echo done"
I get an npm install error that can't find some module, but it looks like I'm the right user
However if I manually do it as two steps it does work... but I'm trying to put this in a bash script, so that I can keep doing operations on the host, so I think I need it as one.
root#host$ lxc exec my-containter -- sudo --login --user ubuntu
ubuntu#my-container$ eval "cd /home/ubuntu/mydir && pwd && whoami && env && npm install && echo done";
I discovered that my PATH environment variable is different in these two situations, the one that is failing is missing a specific path for nvm/npm. I tried exporting it during the eval command, but it seems like the resources available to me have already been found? What could I do to make the PATH variable populate the same way in the single line scenario?
PATH from 1-line (non-interactive)
PATH=/home/ubuntu/bin:/home/ubuntu/.local/bin:/home/ubuntu/bin:/home/ubuntu/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/snap/bin:/snap/bin
PATH from 2-lines (interactive)
PATH=/home/ubuntu/bin:/home/ubuntu/.local/bin:/home/ubuntu/.nvm/versions/node/v8.9.4/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/snap/bin
I've also noticed this nvm code at the bottom on my .bashrc file. From what I've read it sounds like the .bashrc file only gets executed in interactive mode.
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
The below command should do the job for you
lxc exec my-containter -- sudo --login --user ubuntu bash -ilc "cd /home/ubuntu/mydir && pwd && whoami && npm install && echo done"
The .bashrc file has below at the top
case $- in
*i*) ;;
*) return;;
This code prevents the rest of the part of .bashrc to be executed in case of a non-interactive bash. So to make it interactive you should add the -i flag
I'm getting the following build error when compiling my react-native project in Xcode env: node: No such file or directory
Not sure whats causing it?
Node v8.9.4
React-Native v0.50.4
NPM v5.6.0
And I'm using nvm
if you are using nvm do
sudo ln -s "$(which node)" /usr/local/bin/node
this will link current nvm to your usr local and next time Xcode will find the correct node path and version
Xcode have some issues finding node from nvm, try this inside the script that throws the error:
# Setup nvm and set node
[ -z "$NVM_DIR" ] && export NVM_DIR="$HOME/.nvm"
if [[ -s "$HOME/.nvm/nvm.sh" ]]; then
. "$HOME/.nvm/nvm.sh"
elif [[ -x "$(command -v brew)" && -s "$(brew --prefix nvm)/nvm.sh" ]]; then
. "$(brew --prefix nvm)/nvm.sh"
fi
[ -z "$NODE_BINARY" ] && export NODE_BINARY="node"
$NODE_BINARY ../node_modules/#sentry/cli/bin/sentry-cli upload-dsym
Here is one of the solutions for this error if you're using nvm and sentry: https://docs.sentry.io/clients/react-native/manual-setup/#using-node-with-nvm
In my case, this was related to an old sentry configuration and the fact that I use nvm.
Following https://docs.sentry.io/platforms/react-native/manual-setup/manual-setup/
you should be able to execute ln -s $(which node) /usr/local/bin/node and get it fixed
Add this at the top of the script that's failing (in Project -> build phases):
. ~/.nvm/nvm.sh
The solution I used documented here, was to create a script at /usr/local/bin/node that calls nvm
#!/usr/bin/env sh
# Use the version of node specified in .nvmrc to run the supplied command
export NVM_DIR="$HOME/.nvm"
[ -s "/usr/local/opt/nvm/nvm.sh" ] && \. "/usr/local/opt/nvm/nvm.sh" # This loads nvm
nvm_rc_version > /dev/null 2> /dev/null
HAS_NVM_RC=$?
if [[ "$HAS_NVM_RC" == "0" ]] ; then
nvm run $*
else
nvm run default $*
fi
exit $?
I have a fresh mac in front of me, I installed homebrew (just fine), and oh my zsh (just fine).
I'm trying to install autojump which is a intelligent database of directories. For example, you can 'jump' to ~/Documents with j doc in terminal.
I did this
brew install autojump
I already have my .zshrc that looks fine I think. I added the line into it that it said:
[[ -s `brew --prefix`/etc/autojump.sh ]] && . `brew --prefix`/etc/autojump.sh
When I start iterm2 I get the following warning:
/usr/local/Cellar/autojump/21.3.0/etc/autojump.bash:13: command not found: complete
/usr/local/Cellar/autojump/21.3.0/etc/autojump.bash:55: = not found
I have used brew to install other things, and I can run autojump -s successfully so I know it is seeing the $path. I don't know what else could be wrong though, as this is all a fresh install.
In your .zshrc, you must source autojump.zsh, not autojump.bash
(I do not know where it will be located on a Mac, but it will be in same folder as autojump.bash).
On Ubuntu, here is what you need to append at the end of your .zshrc:
source /usr/share/autojump/autojump.zsh
To fix the problem, you should update the line:
[[ -s `brew --prefix`/etc/autojump.sh ]] && . `brew --prefix`/etc/autojump.sh
to say:
[[ -s `brew --prefix`/etc/autojump.zsh ]] && . `brew --prefix`/etc/autojump.zsh
i.e. use the .zsh version of the autojump script. That fixed it for me.
That file has no Shebang. This means that it is probably getting interpreted by Zsh.
This is a problem because complete is a Bash builtin.
Perhaps this can be a fix for you, or maybe
[[ -s `brew --prefix`/etc/autojump.sh ]] && bash `brew --prefix`/etc/autojump.sh
In my case, comment out
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
solved the issue.
You need to add
[[ -s `brew --prefix`/etc/autojump.sh ]] && . `brew --prefix`/etc/autojump.sh
to your ~/.bash_profile. Homebrew tells you this when you install but I didn't notice it the first time and came to this webpage as a result.
In my case, I solve this issue adding :
autoload bashcompinit && bashcompinit
Before the first complete command.
I've used this link : Fixed! az.completion:10: command not found: complete
If you are mac user using .zsh
just add the following to your .zsrc file
autoload -U +X bashcompinit && bashcompinit
autoload -U +X compinit && compinit
for more info refer to link : https://github.com/eddiezane/lunchy/issues/57
I'm trying to change my command promt in terminal. I keep getting the error:
-bash: __git_ps1: command not found
I've tried it just by typing it into the terminal as is: __git_ps1. I've also tried it out in the .bash_profile
if [ -f ~/.git-completion.bash ]; then
source ~/.git-completion.bash
export PS1='[\W]$(__git_ps1 "(%s)"): '
fi
As you might be able to see/tell, yes, I do have the auto-completion installed and it does work great!
I came across this question: " PS1 env variable does not work on mac " which gives the code
alias __git_ps1="git branch 2>/dev/null | grep '*' | sed 's/* \(.*\)/(\1)/'"
So I add it to my .bash_profile hoping that it will change something. Well, it did. It just changed the error output.
Here's the .bash_profile with the addition:
alias __git_ps1="git branch 2>/dev/null | grep '*' | sed 's/* \(.*\)/(\1)/'"
if [ -f ~/.git-completion.bash ]; then
source ~/.git-completion.bash
export PS1='[\W]$(__git_ps1 "(%s)"): '
fi
And now here's the changed error output:
sed: (%s): No such file or directory
Note: I've also moved the alias below the source with no difference. I have git version 1.7.12.1
This should be a simple change. Can someone please help me?
Edit 10/13/12
No, I definitely do not want to define __git_ps1 myself but was just trying to see if it would be recognized by doing so. Yes, I have the .git-completion.bash file installed. Here's how I got auto completion on my machine.
cd ~
curl -OL https://github.com/git/git/raw/master/contrib/completion/git-completion.bash
mv ~/git.completion.bash ~/.git-completion.bash
A ls -la then lists the .git-completion.bash file.
Edit 10/13/12 - Solved by Mark Longair (below)
The following code worked for me in the .bash_profile while others did not...
if [ -f ~/.git-prompt.sh ]; then
source ~/.git-prompt.sh
export PS1='Geoff[\W]$(__git_ps1 "(%s)"): '
fi
You've installed the version of git-completion.bash from master - in git's development history this is after a commit that split out the __git_ps1 function from the completion functionality into a new file (git-prompt.sh). The commit that introduced this change, which explains the rationale, is af31a456.
I would still suggest that you just source the version of git-completion.bash (or git-prompt.sh) that is bundled with your installation of git.
However, if for some reason you still want to use this functionality by using scripts separately downloaded from master, you should download git-prompt.sh similarly:
curl -o ~/.git-prompt.sh \
https://raw.githubusercontent.com/git/git/master/contrib/completion/git-prompt.sh
... and add the following line to your ~/.bash_profile:
source ~/.git-prompt.sh
Then your PS1 variable that includes __git_ps1 '%s' should work fine.
After upgrading to OSX 10.9 Mavericks I had to reference the following files to get git shell command completion and git prompt to work again.
From my .bash_profile or similar:
if [ -f /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-completion.bash ]; then
. /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-completion.bash
fi
source /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-prompt.sh
#shell prompt example
PS1='\u $(__git_ps1 "(%s)")\$ '
You should
$ brew install bash bash-completion git
Then source "$(brew --prefix)/etc/bash_completion" in your .bashrc.
Following worked for me like a charm:
Run following in your Terminal:
curl -L https://raw.github.com/git/git/master/contrib/completion/git-prompt.sh > ~/.bash_git
Open/Create bash_profile:
$ vi ~/.bash_profile
Add following to the file:
source ~/.bash_git
export PS1='\[\033[01;32m\]os \[\033[01;34m\]\w $(__git_ps1 "[%s]")\$\[\033[00m\] '
export GIT_PS1_SHOWDIRTYSTATE=1
export GIT_PS1_SHOWUPSTREAM="auto"
Finally, source it using:
$ source ~/.bash_profile
This will solve the problem of bash: __git_ps1: command not found.
Also your prompt will change to "os ". To change "os" to something else, modify "os" string in export PS1 line.
Solution for MacOS Sierra and git version 2.10.1 <2017-2-06>
Step 1: Install the Git
You can skip this step if you already installed the latest git.
Download git package from browser https://git-scm.com/download/
Note: if you install with curl [option] https://... option to download, you would have to make sure your system support SSL. So for new comer, to download from browser and install directly from git installer is much easier.
Installation Verification:
Show where is your git directory at: which git
Show which version your git currently is: git --version current version should be 2.10.1.
Step 2: Add your git profile to your shell
Open your shell profile:
nano ~/.bash_profile or nano ~/.bashrc Depends on where your modification is.
Add the following code to the file:
source /usr/local/git/contrib/completion/git-completion.bash
source /usr/local/git/contrib/completion/git-prompt.sh
Note: git installation location changed from opt/ directory to usr/local/ after OSX upgrade to El Capitain, and this is why some of the old answer above doesn't work anymore in MacOS Sierra.
Add the following code to your PS1 configuration:
Option 1: add directly to your PS1: export PS1='\w$(__git_ps1 "(%s)") > '
I prefer this simple approach since I already know the .git-completion.bash is there in my home directory, and I can add other prompt format in the front of it. here is my personal prompt for your reference: export PS1='\t H#\! \u:\w$(__git_ps1 "{%s}") -->> '
Option 2: Add a selection script
if [ -f ~/.git-completion.bash ]; then
export PS1='\w$(__git_ps1 "(%s)") > '
fi
Save and use the profile: source ~/.bash_profile or source ~/.bashrc
Now you should see the git prompt working properly and shows which branch you are in right now.
High Sierra clean solution with colors !
No downloads. No brew. No Xcode
Just add it to your ~/.bashrc or ~/.bash_profile
export CLICOLOR=1
[ -f /Library/Developer/CommandLineTools/usr/share/git-core/git-prompt.sh ] && . /Library/Developer/CommandLineTools/usr/share/git-core/git-prompt.sh
export GIT_PS1_SHOWCOLORHINTS=1
export GIT_PS1_SHOWDIRTYSTATE=1
export GIT_PS1_SHOWUPSTREAM="auto"
PROMPT_COMMAND='__git_ps1 "\h:\W \u" "\\\$ "'
I had same problem when upgrading to Yosemite.
I just had to modify ~/.bashrc to source /usr/local/etc/bash_completion.d/git-prompt.sh instead of the old path.
then re-source your . ~/.bashrc to get the effect.
__git_ps1 for bash is now found in git-prompt.sh in /usr/local/etc/bash_completion.d on my brew installed git version 1.8.1.5
this works in OS 10.8 in the .bash_profile
if [ -f ~/.git-prompt.sh ]; then
source ~/.git-prompt.sh
export PS1='YOURNAME[\W]$(__git_ps1 "(%s)"): '
fi
For macports I had to add: source /opt/local/share/git-core/git-prompt.sh to my ./profile
If you're hoping to use Homebrew to upgrade Git and you've let your system become out-of-date in general (as I did), you may need to bring Homebrew itself up-to-date first (as per brew update: The following untracked working tree files would be overwritten by merge: thanks #chris-frisina)
First bring Homebrew into line with the current version
cd /usr/local
git fetch origin
git reset --hard origin/master
Then update Git:
brew upgrade git
Problem Solved! ;-)
At least with Xcode 6, you already have git-completion.bash. It's inside the Xcode app bundle.
Just add this to your .bashrc:
source `xcode-select -p`/usr/share/git-core/git-completion.bash
Download the files git-prompt.sh and git-completion.bash from this Git completion
Rename the files.
Move those files to your home directory.
Add the source file in to the .bash_profile
source ~/git-completion0.bash
source ~/git-prompt0.sh
and four to trigger the code block.
I know it's not a real answer...
I had some strange issues with sourcing git-prompt.sh in my .bashrc so I started to look for other solution. This one: http://www.jqno.nl/post/2012/04/02/howto-display-the-current-git-branch-in-your-prompt/ doesn't use __git_ps1 and author claims it works also on Mac (for now it works perfectly on my Ubuntu and it's easy to tweak).
I hope it helps!
I was doing the course on Udacity for git hub and was having this same issue. Here is my final code that make is work correctly.
# Change command prompt
alias __git_ps1="git branch 2>/dev/null | grep '*' | sed 's/* \ . (.*\)/(\1)/'"
if [ -f ~/.git-completion.bash ]; then
source ~/.git-completion.bash
export PS1='[\W]$(__git_ps1 "(%s)"): '
fi
source ~/.git-prompt.sh
export GIT_PS1_SHOWDIRTYSTATE=1
# '\u' adds the name of the current user to the prompt
# '\$(__git_ps1)' adds git-related stuff
# '\W' adds the name of the current directory
export PS1="$purple\u$green\$(__git_ps1)$blue \W $ $reset"
It works!

# For more info:
cat ~/.git-prompt.bash | sed -r -n -e '1,/^[^\s*#]/p' | head -n -2
This one worked for me, and it has colored git output and an indicator in the prompt whether files have changed / been added, right baked into it:
GIT_PS1_SHOWDIRTYSTATE=true
. /usr/local/Cellar/git/1.8.5.2/etc/bash_completion.d/git-completion.bash
. /usr/local/Cellar/git/1.8.5.2/etc/bash_completion.d/git-prompt.sh
PS1='\[\033[32m\]\u#\h\[\033[00m\]:\[\033[34m\]\w\[\033[31m\]$(__git_ps1)\[\033[00m\]\$ '
Be sure to use the correct path! I used homebrew to install git, use brew list git to get the path to your current installation.
Would be nice not to use a hard coded path, but don't know how to get the path to the current installation.
More infos here: http://en.newinstance.it/2010/05/23/git-autocompletion-and-enhanced-bash-prompt/
For git, there are /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-prompt.sh. And please look /etc/bashrc_Apple_Terminal too.
So, I put these in ~/.bash_profile:
if [ -f /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-prompt.sh ]; then
. /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-prompt.sh
export GIT_PS1_SHOWCOLORHINTS=1
export GIT_PS1_SHOWDIRTYSTATE=1
PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND; }__git_ps1 '\u:\w' '\\\$ '"
fi
Yet another option I just installed on Mojave: magicmonty/bash-git-prompt
Run (brew update) and brew install bash-git-prompt or brew install --HEAD bash-git-prompt
Then to your ~/.bash_profile or ~/.bashrc:
if [ -f "$(brew --prefix)/opt/bash-git-prompt/share/gitprompt.sh" ]; then
__GIT_PROMPT_DIR=$(brew --prefix)/opt/bash-git-prompt/share
GIT_PROMPT_ONLY_IN_REPO=1
source "$(brew --prefix)/opt/bash-git-prompt/share/gitprompt.sh"
fi
I'm happy.
Please not that, if you haven't installed git through Xcode or home-brew, you'll likely find the bash scripts haysclarks refers to in /Library/Developer/CommandLineTools/, and not in /Applications/Xcode.app/Contents/Developer/, thus making the lines to include within .bashrc the following:
if [ -f /Library/Developer/CommandLineTools/usr/share/git-core/git-completion.bash ]; then
. /Library/Developer/CommandLineTools/usr/share/git-core/git-completion.bash
fi
source /Library/Developer/CommandLineTools/usr/share/git-core/git-prompt.sh
You'll need those lines if you wish to use git-prompt as well.

Copy/Download the following files and copy them to home directory: ~/
git-completion.bash
git-prompt.sh
For the bash_profile, add this at the beginning:
source ~/git-completion.bash
source ~/git-prompt.sh
export GIT_PS1_SHOWDIRTYSTATE=1

I installed rvm using commands which by convention should return rvm as a function
1) bash < <(curl -sk https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
2) echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile
3) source .bash_profile
4) type rvm | head -1
should return ("rvm is a function") // and it returned, rails was perfectly fine yesterday.
It worked perfectly yesterday, but now today when I am checking out rails. Its saying rails is not installed.
type rvm | head -1
returns "RVM is Hashed".
Here is something that i got from official site, but i dont know next I should do.
So the question is:
What should be done to get the rvm installed in a function mode and not binary mode?
One possible reason might be that RVM is not being accessible from .bash_profile file so try out using .bashrc file instead of .bash_profile.
Copy and paste following commands into the terminal
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bashrc
source ~/.bashrc
Hope it works for you. worked for me cheers !!
===== Edit =====
The following should work in all cases :
curl -L https://get.rvm.io | bash -s stable
echo "source $HOME/.rvm/scripts/rvm" >> ~/.bash_profile
echo "source $HOME/.rvm/scripts/rvm" >> ~/.bashrc
You should use a login shell in console you can test it by issuing:
$SHELL -l
it is possible to configure your terminal to use a login shell:
https://rvm.io/integration/gnome-terminal/
https://rvm.io/workflow/screen/
for other terminal emulators you need to read respective manual
