I can confirm the error is in grb_git_promit. What happens is the second lines typed in shell is overwriting the first line. Can anyone could help me with this?
EDIT:
grb_git_prompt() {
local g="$(__gitdir)"
if [ -n "$g" ]; then
local MINUTES_SINCE_LAST_COMMIT=`minutes_since_last_commit`
if [ "$MINUTES_SINCE_LAST_COMMIT" -gt 30 ]; then
local COLOR="\[\033[0;31m\]"
elif [ "$MINUTES_SINCE_LAST_COMMIT" -gt 10 ]; then
local COLOR="\[\033[0;37m\]"
else
local COLOR="\[\033[0;32m\]"
fi
local SINCE_LAST_COMMIT="${COLOR}$(minutes_since_last_commit)m$"
# The __git_ps1 function inserts the current git branch where %s is
echo "$(__git_ps1 '(%s|')${SINCE_LAST_COMMIT}"
fi
}
From the bash manual: The backslash character '\' may be used to remove any special meaning for the next character read and for line continuation.
So, you literally need a newline (press ENTER ) after you type the \ to tell the shell you want to enter more parameters but on a separate line.
When you have colors and other non-printing escape sequences in your prompt, you have to surround them with escaped single brackets. Here is a simple example:
PS1='\[\033[38;5;1m\]some red text\[\033[0m\]\$ '
Which will cause the prompt to display "some red text" in red and the dollar sign (or "#") in the default color.
Here is another way to do the same thing:
red='\033[38;5;1m'
none='\033[0m'
PS1='\[$red\]some red text\[$none\]\$ '
By the way, to do this more portably and have less complex build-up of variables:
red=$(tput setaf 1)
none=$(tput sgr0)
See man 5 terminfo
for more information on the settings.
