Want to count the number of lines after the first line
hi,

How can i count the number of lines after the first line in a flat file in unix?

Say i have a flat file with a header like:
Student Name Student ID ....

So you want the total number of line minus one:

Code:
expr $(wc -l <filename) - 1

this is giving me a syntax error.
Code:
$ cnt=`expr $(wc -l <REGIN) -1`
expr: syntax error

try..

Code:
 
awk 'END{print NR-1}' filename

If your shell does not support the $( ... ) syntax, split up the command in two steps:

Code:
num=`wc -l <REGIN`
cnt=`expr $num - 1`

Make also sure, there is a blank before and after the minus sign in the expr command!

here is my solution:

Code:
tot_cnt=$((`cat filename | wc -l`  -1 ))

This may not help you with huge files.!!
Code:
tot_cnt=$( expr $(wc -l filename) - 1 )

Make sure that you give spaces properly
