[clug] Command of the Hour

[Alex Satrapa]

Not strictly a command, but more hacking with ZSH:

> function settitle

> {

>    PS1=`echo "%{\\e[$1m[%n@%m:%~]\\e[0m\n\\e[$2m%}%D{%k:%M} [%?|%!]%# 
> %{\\e[0m%} "`
>    return 0
> }
>
> # I often like using shortprompt '41;37;1'
> function shortprompt
> {
>    PS1=`echo "%{\\e[\$1m%}%T [%?|%!]%#%{\\e[0m%} "`
>    return 0

What does this achieve?

If I open up an xterm, it changes the prompt so that I get two lines  
like this:

> [alex at Lancelot:~/Documents/src]
> 16:22 [0|2367]%

but also changes the xterm title to become:

> alex at Lancelot: ~/Documents/src


Then if I run a command such as "vi ~/.zshrc" the title becomes:

> alex at Lancelot:~/Documents/src - vi ~/.zshrc


The nifty thing about this is that in Terminal my "Window" menu will  
contain a list of shells each showing what I was working on at the time.

Thanks to Matthew Hawkins for these tips (10 years ago)!
