Why not just have the script do an ln -nfs
and make the user invoke it with sudo ./update_git.py
? Means they know it's sudo asking for the password, not your script (if they can't read .py)
Also, this should do the same job:
#!/usr/bin/env zsh
FROM_DIR=/usr/bin
TO_DIR=/usr/local/git/bin
for i in $FROM_DIR/git*; ln -nfs $i $(echo -n $i | sed -Ee "s#$FROM_DIR#$TO_DIR#")
Wondered why my git is coming from /usr/local/bin
as per installed by homebrew, turns out I put /usr/local/bin
before /usr/bin
in my PATH, so no need to fiddle the symlinks, the shell picks homebrew's git to use already. And the git commands in /usr/bin
are what Xcode expects them to be (shouldn't matter that much, but leaving them unchanged is always nice.)
Thanks for the Shell script. I wanted an excuse to play about with Python.
What caius said: don't do sudo inside the script, require that it gets called with sudo. Also, consider a "and your original files have been moved to ${SAFEPLACE}" option :-D
Applied some suggestions.
Script requires sudo to run and uses the OS module to create the symlinks.
Just a small note : caius' script does the contrary of the python script.
If you want to update git and use it as default, FROM_DIR and TO_DIR should be exchanged in the zsh script.
Thanks, maybe one day xcode will update their git..
The version of Git that comes with Xcode is fairly recent. This script is just for those who want to use the development builds of Git.
Can any one help me. I am setting up my local development environment. I have a server (MAC OS X Lion Server) and want that to house git and use the repository over http. I followed all the steps from http://www.pkgbox.org/wordpress/2011/08/setting-up-a-git-server-on-macos-x-lion/ but now I get fatal: http:/myname@server/repo/test-project.git/info/refs not found did you run git update-server-info on the server? Please help i am running out on time... I want to use git and start this project...
Notice the 'sudo' at line 18? That means you'll have to enter your password. No need to panic, I'm not trying to spoof you but need this to modify files in '/usr/bin'.
