No carriage return using temp parameter

[yc_2]

Hi,

Don't understand why there is no carriage return for the temp parameter set in a script. Below is the example:

#!/usr/bin/sh
V_TEMPDIR=/usr/local/etc
V_PRTDIR=`ll $V_TEMPDIR`
print $V_PRTDIR

Any pointer or work around is appreciated.

Everybody has found this out at some time.

It is because of your shell's $IFS variable. This is the internal field seperator for the shell which by default includes a carriage return. In other words, the shell sees the carriage return as a seperator between "tokens" or words. The solution goes soemthing like this

#!/usr/bin/sh

V_TEMPDIR=/usr/local/etc

TMPIFS=$IFS
IFS=" "

V_PRTDIR=`ll $V_TEMPDIR`
print $V_PRTDIR

IFS=$TMPIFS
