Subject: truncating string in .zprofile
Date: Wed, 20 Mar 2013 19:28:27 +0100 [thread overview]
Message-ID: <mailbox-13443-1363803840-947330@pepper.0.0.200> (raw)
I have the following prexec() in my profile;
preexec () { print -Pn "\033k\033\134\033k[$1]\033\134" }
This prints the command in the screen caption for that window.
What I want to do is limit this window title to n chars.
However, I cannot manipulate the `$1' in the print string.
Even if I try.
substring=$1
preexec () { print -Pn "\033k\033\134\033k[$substring]\033\134" }
then there is no value printed for $substring.
What is the solution?
Thank
Eric Smith
