Hi! You can use grep for this.


Code:
check=`grep 06 FILENAME > /dev/null; echo $?`
if [ "$check" -eq "0" ]; then
var1=1
else
var1=0
fi

Hi,

grep has the -q or --silent option for this. Try


Code:
grep -q "test" file && a=found || a=missing

which will set $a to found if "test" was found in file. Else $a will be set to missing.

When i search for a string in any file i use this:


Code:
find ./ -name "filename" | xargs grep "string_to_found"

In this way you can specify what kind of files are you searching for
"filename" or "file*" or "?ile_+.txt" or .....

it's clear and simple.
