Breaking input with "read" command
In this post, Perderabo's script says
echo 05/06/25 14:15:56 | IFS=" /:" read Y1 M1 D1 h1 m1 s1 which, if I am not wrong, will break the input into Y1, M1 et al. I tried the following in my code Code:
#! /bin/ksh # per.sh typeset -R2 HOUR=00 typeset -R2 MIN=00 typeset -R2 SEC=00 TIME=09:12:23 echo $TIME | IFS=" :" read HOUR MIN SEC echo $HOUR$MIN$SEC echo $TIME [~/temp]$ ksh per.sh 000000 09:12:23 [~/temp]$ uname -a Linux staci21 2.4.21-27.ELsmp #1 SMP Wed Dec 1 21:59:02 EST 2004 i686 i686 i386 GNU/Linux Any idea what is wrong in my code ? Am I missing something ? Thanks, Vino

it works fine on Solaris, but breaks on RH.
the "problem" is read-ing the vars off the 'pipe' - reading off the pipe creats a child process. Once read-ing is done, child process exits - no vars get exported to the parent. Just as an illustration: Code:
#! /bin/ksh
# per.sh
typeset -R2 HOUR=00
typeset -R2 MIN=00
typeset -R2 SEC=00
TIME=09:12:23
echo "${TIME}" > /tmp/vino.txt
IFS=" :" read HOUR MIN SEC < /tmp/vino.txt
echo $HOUR$MIN$SEC
echo $TIME
