expr: syntax error
Hi All,

This is a piece of code from one of my scripts:


Code:
t1=`cat temp3.21447 | grep WEALTHTOUC_TRANS_20100409_233127.txt.txt.TRG | awk '{print $3}' | cut -c1-5`
t2=`cat temp3.21447 | grep WEALTHTOUC_TRANS_20100409_233127.txt.txt.TRG | awk '{print $5}' | cut -c1-5`
 
#t1=23:43
#t2=23:40
        shr=`echo $t1 | cut -c1-2`
        smin=`echo $t1 | cut -c4-5`
        stot=`expr $shr \* 60`
        stot=`expr $stot + $smin`
        ehr=`echo $t2 | cut -c1-2`
        emin=`echo $t2 | cut -c4-5`
        etot=`expr $ehr \* 60`
        etot=`expr $etot + $emin`
        if [ $stot -gt $etot ]
        then
        etot=`expr $etot + 1440`
        fi
        diff=`expr $etot - $stot`

its giving me 3 times syntax error, though its giving the desired result. but this error is very annoying.
Code:
expr: syntax error
expr: syntax error
expr: syntax error

I'm using #!/bin/ksh
at the top of my script. Pls help.Thanks
