I'd like to set my bash prompt to a fixed width, and make up the difference in space before the $, so whether long or short, my prompt remains the same width:
[name@host] ~/Directory/Dir...Another/LastDir $
[name@host] ~/Directory(branch) $
Currently, in a short directory path my prompt looks something like this:
[name@host] ~/Directory(branch) $
a deeper directory path looks like this:
[name@host] ~/Directory/Dir...Another/LastDir $
You can see I've truncated the PWD in the middle so I can see where the path begins, and where it ends. I'd like to make up the difference before the $.
Here is my current prompt:
# keep working directory to 30 chars, center tuncated
prompt_pwd() {
local pwd_symbol="..."
local pwd_length=30
newPWD="${PWD/#$HOME/~}"
[ ${#newPWD} -gt ${pwd_length} ] && newPWD=${newPWD:0:12}${pwd_symbol}${newPWD:${#newPWD}-15}
}
# set prompt
prompt_color() {
PROMPT_COMMAND='prompt_pwd;history -a;title_git'
PS1="${WHITEONMAGENTA}[\u@\h]${MAGENTA} \w\$(parse_git_branch) ${MAGENTABOLD}\$${PS_CLEAR} "
PS1=${PS1//\\w/\$\{newPWD\}}
PS2="${WHITEONTEAL}>${PS_CLEAR} "
}
In my search, I found A Prompt the Width of Your Term which does do some fill, but couldn't get it working for this particular prompt.
