Overview#
If you work every day on a Linux shell and need to manage projects using Git or SVN version control systems, it could be useful to see information about them directly in your bash prompt.
You can easily do that with some changes to the /etc/bashrc file of your Linux.
Configuration#
Go to the end of that file and add the following lines:
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(git::\1)/'
}
parse_svn_branch() {
parse_svn_url | sed -e 's#^'"$(parse_svn_repository_root)"'##g' | awk -F / '{print "(svn::"$1 "/" $2 ")"}'
}
parse_svn_url() {
svn info 2>/dev/null | grep -e '^URL*' | sed -e 's#^URL: *\(.*\)#\1#g '
}
parse_svn_repository_root() {
svn info 2>/dev/null | grep -e '^Repository Root:*' | sed -e 's#^Repository Root: *\(.*\)#\1/#g '
}
# vim:ts=4:sw=4
# Colors in Terminal
if [ $USER = root ]; then
PS1='\[\033[1;31m\][\u@\h \W]\$\[\033[0m\] '
else
#PS1='\[\033[01;32m\]\u@\h\[\033[00m\] \[\033[01;34m\]\W\[\033[00m\]\[\033[1;32m\]\$\[\033[m\] '
PS1="\[\033[01;32m\]\u@\h\[\033[00m\] \[\033[01;34m\]\W\[\033[00m\]\[\033[1;32m\]\[\033[31m\]$(parse_git_branch)$(parse_svn_branch)\[\033[00m\]\[\033[1;32m\]\$\[\033[m\] "We’ve added some Bash functions to call git and svn commands and retrieve information about your version control status. Then we override the PS1 variable, which Bash uses to customize the prompt, adding colors (red for root user) and calling the defined functions.
Usage#
The result, when you enter a repository folder, is the following (for a git project):
mmornati@desktop raskiidoc(git::master)$This indicates the repository type (git) and the current branch name (master).
