Problem in For Loop

The Observer · #1 (**permalink**) 05-28-2008

Hi,
While executing for loop in a shell script , I am getting error.

for i in `cat FILE`
> do
> if [ `cat $i | tr " ' " "\n" | grep ^UNB | cut -f3 -d+ | cut -f1 -d:` -eq WF0000010001 ]; then
> `ls $i` >> /gentran/GIS_42/users/FILES/SENDER_ID
> fi
> done

Error :- ksh[3]: WF0000010001: bad number

Please help me out why this is giving error. I tried many options but invain.

I am using ksh shell.

If you want to compare two strings, use the string comparisons operator == instead of the arithmetic operator -eq

Note: It would be better if you use echo instaed cat. and as per RIPAT use string comparision operator in place of -eq and put the string in "".

Regards,
Siba
