try assinging the value of the

wc -l

to a variable before going to test.

Also enclose the variable $dline inside ""

~# grt=`sort -nr filename|head -1`
~# JJ=`wc -l filename."$KK"| awk '{ print $1 }'`
~# if [ "$grt" ==  "$JJ" ]; then echo $JJ; else echo "Not true"; fi
Not true

I dint get wat u aiming to explain....

comparing two numbers should be done via

 ==

rather than

-eq

, as well. rest is for your understanding .

Wrong.
== is for string comparison and -eq is for numeric comparison.

I can't see where the while loop in your script in post #1 reads from; as is it would read from stdin which might be your terminal. Are you sure the variable dline holds a valid file name?

If you don't want wc to print a filename, don't provide one as an argument. Instead, redirect the command's standard input:

wc -l < filename
