UNIX for Dummies Questions & Answers

hello,

i have an statement which i have to correct because it shows the wrong result.

i want to search an excat string in another string, command "grep" shows the wrong result:

example:

STRINGS="string1 string2 string3"
search_string="string"

incorrect:
if [ `echo "${STRINGS}" | grep "${search_string}" > /dev/null 2>/dev/null; \
echo $?` -gt 0 ]
then
echo "not found"
fi

my solution will be a "for statement":
exists="N"
for string in ${STRINGS}
do
if [ "${string}" = "${search_string}" ]
then
exists="J"
break
fi
done
echo $exists

is there any solution with one command. i will use in a shell script, also it possible to use perl for this but my experience in perl is very small ...

regards
