Automate git rebase -i to remove selected commits
# Perl onliner is used to delete selected commits from the git rebase -i commit text
# The range of commits includes extra commit to prevent git from doing noop when
# all commits after certain point are to be backed out.
# Some notes on the Perl onliner:
# -n: run the script as specified by -e in the while(<>) loop
# -i: modify the file inplace
# -e: command to run
env GIT_SEQUENCE_EDITOR="perl -ni -e 'print unless /^pick (7d105ae|08fe503|97bf990)/'" git rebase -i <earliest_commit_to_backout>^^

Key config to make cgit work under nginx
# The .css and image files required by CGit should be copied to /var/www/cgit-css
# as nginx concat the matched URI with the document root which is very different
# from Apache's Alias directive.
location /cgit-css {
root /var/www;
index index.html index.htm;
}
# The cgit.cgi program does not work if the whole URI is passed as PATH_INFO.
# Strip the CGI program name from URI and set PATH_INFO to the remaining part,
