I like < :
Code:
COUNT=$( wc -l < file_name )

Is "/app/reporting/daily/temp/*OUT*.psv" always one file? If not, what do you want. Usually, we use "for FILE in /app/reporting/daily/temp/*OUT*.psv ; do ... done".

Thanks the record count worked . The output has a header as well. The record count is coming as 7 which includes the header. Should be 6. I tried
Code:
COUNT=$( wc -l < file_name ) -1

but not worked.

Code:
time|tourit|nofdays|rbcid|blank|type|value|nill|valuedesc|name

try below ...

Code:
COUNT=$(grep -v rbcid | wc -l)

Old 06-15-2013
Thanks but if in future the column change to rbc_id the script would fail. May be i can try
Code:
 grep -v *rbc* | wc -l

unless there is any better suggestion

Your regular expression won't work. The leading * will be treated literally.

Try:
Code:
$ grep "rbc_\?id" file
rbc_id
rbcid

or you can grep out another category that most very likely will not change (i.e., time, name, etc.) ...

I just found an easy solution Smilie . As i just want to get the output minus the header , so i used minus as below in my code:
Code:
COUNT=$( wc -l < /app/reporting/daily/temp/final.psv
echo "RECORD_COUNT="$((COUNT - 1)) >> /app/reporting/daily/temp/final.psv

My output is now 6
Code:
RECORD_COUNT=6
