Why for loop is acting weird
Hey i have a small script in which i check if a file with that pattern exists or not. If present then i go ahead with further processing.

In the present situation i have only one file with that name and for loop is reading twice. Here is the script. And the output of debug mode. Please help.
Quote:
myfilepattern=$1_$2
fullpattern=${myfilepattern}_$NEW_DT.dat
integer filecount=0
for file in $fullpattern ; do
[ "$file" != "$fullpattern" ] && filecount=$filecount+1
done

if (( $filecount == 1 )); then

I pass 2 parameters to the script.

and the debug output shows it;s reading 2 times in the for loop.

Quote:
files=AUD01_CARE_DLY_20060912 .dat
+ myfilepattern=AUD01_CARE_DLY
+ fullpattern=AUD01_CARE_DLY_20060912 .dat
+ typeset -i filecount=0
+ [ AUD01_CARE_DLY_20060912 != AUD01_CARE_DLY_20060912 .dat ]
+ filecount=0+1
+ [ .dat != AUD01_CARE_DLY_20060912 .dat ]
+ filecount=1+1
+ (( 2 == 1 ))

lr_environment

LR_ENVIRONMENT.IN(1)					  LogReport's Lire Documentation				      LR_ENVIRONMENT.IN(1)

NAME

       lr_environment - Export Lire configuration in shell script form

SYNOPSIS

       eval `lr_environment`

DESCRIPTION

       The lr_environment command is used to import the Lire configuration in Lire shell scripts.

       All of Lire configuration variables will be written in a format that can be evaled by the shell.

       Shell scripts don't usually have to use that command, since it is done by the defaults file sourced by each command.

       The old names used by when the configuration was done in shell script are also exported by this script for backward compatibility.
