Yeah you are right tom_cmu. I am using the same thing in my script.

Pls. find more insight on problem :
Suppose i have two jars
Jar1 contains xyz.class , xyz$abc.class, aaa.class
Jar2 contains abc.class bbb$xyz.class, bbb.class and so on.

Queries are ---

1) At runtime if i search for abc.class in jar1 it returns true, because of xyz$abc.class which is incorrect.
It should return true only for jar2 which has file with name abc.class

2) If i have to search for file xyz$abc.class in jar1 how to do that with grep. As grep takes $ as special symbol and i cannot put \ in front of $ to suppress it in variable which contains its name.

Is there way in awk or sed to implement this

Hope I am more clear in stating problem this time. Your reply will be helpfull

snippet of script made is .....

for file in new_files/*.class
do
if [ -f $file ]
then
fntoreplace=`echo $file | cut -d "/" -f2`
echo $fntoreplace
jar -tvf old_jarfiles/$jarname | grep "\<$fntoreplace\>"
