I have a number of scripts that I use almost everyday in my work. I develop and maintain these on my personal laptop. I have a local git repository where I track the changes, and I have a repository on github to which I push my changes.

I do a lot of my work on a remote supercomputer, and I use my scripts there a lot. I would like to keep my remote /home/bin updated with my maintained scripts, but without cluttering the system with my repository.

My current solution does not feel ideal. I have added the following code belowto my .bashrc. Whenever I log in, my repository will be deleted, and I then clone my project from github. Then I copy the script files I want to my bin, and make them executable.

This sort of works, but it does not feel like an elegant solution. I would like to simply download the script files directly, without bothering with the git repository. I never edit my script files from the remote computer anyway, so I just want to get the files from github.

I was thinking that perhaps wget could work, but it did not feel very robust to include the urls to the raw file page at github; if I rename the file I suppose I have to update the code as well. At least my current solution is robust (as long as the github link does not change).

Code in my .bashrc:

REPDIR=mydir
if [ -d $REPDIR ]; then
 rm -rf $REPDIR
 echo "Old repository removed."
fi
cd $HOME
git clone https://github.com/user/myproject
cp $REPDIR/*.py $REPDIR/*.sh /home/user/bin/
chmod +x /home/user/bin/*

Based on Kent's solution, I have defined a function that updates my scripts. To avoid any issues with symlinks, I just unlink everything and relink. that might just be my paranoia, though....

function updatescripts() 
DIR=/home/user/scripts
CURR_DIR=$PWD
cd $DIR
git pull origin master
cd $CURR_DIR
for file in $DIR/*.py $DIR/*.sh; do
 if [ -L $HOME/bin/$(basename $file) ]; then
 unlink $HOME/bin/$(basename $file)
 fi
 ln -s $file $HOME/bin/$(basename $file)
done

on that remote machine, don't do rm then clone, keep the repository somewhere, just do pull. Since you said you will not change the files on that machine, there won't be conflicts.

For the scripts files. Don't do cp, instead, create symbolic links (ln -s) to your target directory.
