Hi Rudi, Your code results if value is null then count is 0.
I also need if static word exist in file,place the value.
Based on your code, below came in my mind.
Code:
while read line
do
if [ $(grep -ic "$line" testgg.qa.txt1) -ne 0 ]; then
Delete=`cat testgg.qa.txt1| egrep -i "Delete" | sed 's/ */ /g' | cut -d" " -f2`
else
Delete=0
fi
done < static_file
I m trying if I can get it in single line and assign to variable.
Regards,
Veera
I have the necessity to use this command:
cat file1 | grep $A | grep $B
where sometime A and, or, B are not set.
For example:
I set A=@
never defined or set B
The above command send a cat error.
Any idea?
Thanks.

zgrep
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.
