how to migrate my bash prompt to zsh
bash, prompt, zsh
Solution
- Use `colors`.
- For path truncation, look at this. Fairly detailed discussion on how his works (I've used something similar in my prompt).
- Color directory names differently: read this answer, which addresses something similar (I think: I'm not really sure what you're asking there).
- Change the terminal title: read this, and the link from (2).
You should also read the Stackoverflow Help Page, specifically the section linked. If you're having trouble with something, edit your question to contain what you've tried and what your issue is.
There are lots of questions on Stackoverflow, as well as Superuser: (Example), and Unix.SX (Example). Plenty to get you started.
Problem
As of some time now I have been very tempted to switch from bash to zsh. There is just one problem, I am very picky about my prompt. I use the terminal all day and it took me a long time to get my prompt to look and behave the way I want it to. By the way, I put it together from different sources and a bit of my own stuff and it may contain errors or not properly written code. All I want to know is if someone knows the code that I can paste into my zshrc that would give me the exact same prompt. The two features that I really enjoy is the variable length working directory that gets adjusted if pwd is too long and the directory separator slashes having different color then the dir names. This prompt also sets a dynamic terminal title. I could not post a picture because of some reputation or something but here is the code. ``` my_prompt() { local NONE="\[\033[0m\]" local COLOR1="\[\033[0;30m\]" local COLOR2="\[\033[0;31m\]" local COLOR3="\[\033[0;32m\]" local COLOR4="\[\033[0;33m\]" local COLOR5="\[\033[0;34m\]" local COLOR6="\[\033[0;35m\]" local COLOR7="\[\033[0;36m\]" local COLOR8="\[\033[0;37m\]" local COLOR9="\[\033[1;30m\]" local COLOR10="\[\033[1;31m\]" local COLOR11="\[\033[1;32m\]" local COLOR12="\[\033[1;33m\]" local COLOR13="\[\033[1;34m\]" local COLOR14="\[\033[1;35m\]" local COLOR15="\[\033[1;36m\]" local COLOR16="\[\033[1;37m\]" # How many characters of the $PWD should be kept local PWDLEN=55 ## Indicate that there has been dir truncation local TRUNC=".." local DIR=${PWD##*/} PWDLEN=$(( ( PWDLEN < ${#DIR} ) ? ${#DIR} : PWDLEN )) TITLE_PWD=${PWD/#$HOME/\~/} local pwdoffset=$(( ${#TITLE_PWD} - PWDLEN )) if [ ${pwdoffset} -gt "0" ] then TITLE_PWD=${TITLE_PWD:$pwdoffset:$PWDLEN} TITLE_PWD=${TRUNC}/${TITLE_PWD#*/} fi local DIR_SEP_COLOR=$COLOR10 local DIR_COLOR=$COLOR5 local HOSTNAME_COLOR=$COLOR5 local AT_COLOR=$COLOR10 local USER_COLOR=$COLOR5 IN=$TITLE_PWD arr=$(echo $IN | tr "/" "\n") unset NEWDIR for x in $arr do if [ "$x" == "~" ] then NEWDIR="$NEWDIR$DIR_COLOR$x" else NEWDIR="$NEWDIR$DIR_SEP_COLOR/$DIR_COLOR$x" fi done TITLEBAR='\[\033]0;\u@\h:${TITLE_PWD}\007\]' MYPS1="${USER_COLOR}\u${AT_COLOR}@${HOSTNAME_COLOR}${HOSTNAME}$DIR_SEP_COLOR:${DIR_COLOR}${NEWDIR}${NONE}" PS1="${TITLEBAR}${MYPS1}${COLOR12}»${NONE} " } PROMPT_COMMAND=my_prompt ``` another thing is that I do not like to do something like ``` echo \`pwd` | grep "/" ``` to get the slashes different color because I would also like to be able to change the color of the directory names as well EDIT and ANSWER: Thank you Simont for your answer. I think your criticism of me not being able to do a search was the exact slap and motivation I needed to get started :) basically I used link number 2 multi color path in prompt to get started. I came up with the following, its not perfect (i.e. random colors ... ) but it is a good starting template. The following is my current .zshrc : ``` prompt_working_dir() { # How many characters of the $PWD should be kept local PWDLEN=55 ## Indicate that there has been dir truncation local TRUNC=".." local DIR=${PWD##*/} local PWDLEN=$(( ( PWDLEN < ${#DIR} ) ? ${#DIR} : PWDLEN )) local TITLE_PWD=${PWD/#$HOME/\~/} local pwdoffset=$(( ${#TITLE_PWD} - PWDLEN )) if [ ${pwdoffset} -gt "0" ] then TITLE_PWD=${TITLE_PWD:$pwdoffset:$PWDLEN} TITLE_PWD=${TRUNC}/${TITLE_PWD#*/} fi IN=$TITLE_PWD arr=(${(s:/:)IN}) unset NEWDIR if [ "$arr[1]" "==" "~" ] then NEWDIR="%{$fg[blue]%}$arr[1]" #delete 1st element arr[1]=() for x in $arr do NEWDIR="${NEWDIR}%{$fg_bold[cyan]%}/%{$reset_color%}%{$fg[blue]%}$x" done elif [ "$arr[1]" "==" ".." ] then NEWDIR="%{$fg[blue]%}$x%{$fg_bold[cyan]%}/" #delete 1st element arr[1]=() for x in $arr do NEWDIR="${NEWDIR}%{$reset_color%}%{$fg[blue]%}$x%{$fg_bold[cyan]%}/" done else for x in $arr do NEWDIR="${NEWDIR}%{$fg_bold[cyan]%}/%{$reset_color%}%{$fg[blue]%}$x" done fi echo "${NEWDIR}" unset PWDLEN unset TRUNC unset DIR unset PWDLEN unset TITLE_PWD unset pwdoffset unset IN unset arr } setopt PROMPT_SUBST autoload -U colors && colors # set window title to user@host %directory----------- precmd () {print -Pn "\e]0;%n@%M: %~\a"} SEP=":" PROMPT='%{$fg[blue]%}%m%{$reset_color%}'\ '%{$fg_bold[cyan]%}@%{$reset_color%}'\ '%{$fg[blue]%}%n%{$reset_color%}'\ '%{$fg_bold[cyan]%}$SEP%{$reset_color%}'\ '$(prompt_working_dir)%{$reset_color%}'\ '%{$fg_bold[cyan]%}»%{$reset_color%} ' ```
