Some useful sysadmin scripts...

• diffdir - run diff recursively to compare two directories
• forgit - run abitrary command for each git repository found
• gitup - pull all branches that are behind, inspired by git-up
• gitrepo - user friendly script for creating bare git-repositories

diffdir example:

Compare all files and subdirs in the current dir with target dir and show the differing lines of each file, before asking to update the target file:

# diffdir -r -t /my/target/dir -v -u

gitup example:

# gitup
   develop              ( up to date )
 * master               ( 1 commits ahead of origin/master )
   tempbranch           ( has no remote on origin )
   testbranch           ( 1 commits behind origin/testbranch )

forgit example:

$ forgit gitup
for ./ocsinventory/: gitup
* master               ( 5 commits ahead of origin/master )
for ./testrepo/: gitup
* develop              ( up to date )   
  master               ( up to date )
  mingren2             ( has no remote on origin )
for ./verktygsstod/git/: gitup
* master               ( up to date )

Install git-prompt.sh

Save git-prompt-sh as ~/.git-prompt.sh Add to ~/.bashrc or equivalent:

[ -f  ~/.git-prompt.sh ] && {
  . ~/.git-prompt.sh
  export PS1="[\033[32m\u@\h\033[0m:\033[33m\w\033[0m]\[\033[35m\]\$(__git_ps1)\[\033[0m\]\n# "
