    Unanswered: Just a hint on this command...

    Hi.

    I was having a minor warning message when my shell started up
    when I decided to fix it for good.
    Even though things are ok now, I did not figure it out
    how the solution works (I read somewhere that this should
    work but no explanation for it).

    Does someone knows what the IF command is doing below ?

    if (( -t 0 )) then
    stty erase ^h
    endif


    Thanks, Serg.

    Thanks, Serg.
    man ksh [for example]

    # determine if there's a controlling tty for this run of the script.
    # if there's none, it means we're running from 'cron' [for example]
    vlad

    This must be a glitch

    I did not post this thread again.
