#2 Re: bash read/readline prepopulation questions Posted by mcortese (213.70.xx.xx) on Fri 7 Mar 2008 at 11:53 Yes, read cannot do what you need. I suggest you simulate the pre-seeding with the ${x:-y} syntax. myownread() { local x echo >&0 -e "$1$2\e[A" read >&0 -p "$1" x eval "$3='${x:-$2}'" } Then use it like this: # Use: # myownread PROMPT PRESEED VAR myownread "Question? " "yes" aaa echo $aaa The above function works with bash and sh. The only problem is that the \e[A sequence that forces the cursor up one line is terminal-specific (you can find the sequence that fits your term by pressing Control-V then the Up key).
