Some useful scripts.

Local update multiple repositories from list. List example is here.

bash git/pull.sh bash/list_example.txt

Script for pushing git repository to all it's remotes. If it's called without arguments it pushes current folder. Else it parses filelist like pull script. List example is here.

bash git/push.sh bash/list_example.txt
# or
bash git/push.sh

Change the author and committer name and e-mail of multiple commits for all branches and tags (original here - https://stackoverflow.com/a/750182). You should run this script from folder with repository to change.

WARNING! These changes are dangerous because they change git history!

# Run this script from folder with repository to change.
bash git/change_author.sh WRONG_EMAIL CORRECT_NAME CORRECT_EMAIL

Copy folder via ssh using tar to current folder. It can be useful for copying folder with large amount of files via ssh. It's faster than pure ssh.

bash bash/ssh_tar.sh user@host /path/to/folder
# or 
bash bash/ssh_tar.sh user@host -p port /path/to/folder

Parse filelist, call command $2 for each folder from filelist $1 and print text $3 for each folder. List example is here.

# to show all directories in file bash/list_example.txt
bash/parse_filelist.sh bash/list_example.txt pwd "Current directory"

Call word count util (wc) for files in directory $1 with extensions $2, $3, $n etc.

# For example to call wc for C and C++ files and headers (files *.c, *.cpp, *.cxx, *.h, *.hpp, *.hxx) run:
bash/wc.sh . c cpp cxx h hpp hxx
