Hi Rudi

Thanks!Smilie

Actually I have trying this now :
Code:
a=`grep -c " " abc.txt`
if [ $a gt 0 ]
then
      {perform rest of code}
fi

But I need to get a better syntax where a simple grep/sed command will help me to find and count any spaces/tabs between any rows (above,middle or below) and also in front and after last of any lines in a row. Can you please help me in that?
Example
Code:
abc.txt :
Space1 [/BOF]
Space2
ABCHSDJRIR|MSDJAS|M|122121
Space3
ASDSDSADSAS|DASDASD|K|12328137 
Space4 ASDSADASDA|qwueiwuqoei|H|1219827918Space5
[/EOF]

Regards

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
