Help with Compare and search content in directory

Hello,
How to search in directory by comparing some string with the content of
directory.
Ex:
I want to compare abhi string with the content of backup directory.
i.e want to check that is there any file in backup directory having name
as abhi

find <PATH> -name "*<STRING>*"

I am very new to unix....so can you please tell me that is this right..
my path is backup/path.txt and string is abhi so now i will be writting
find $backup/path.txt -name "abhi"

is this right?

cd into your backup directory and enter the command:

pwd

pwd should return something similiar to this:

pwd
/home/backup

Then, regardless of what directory you are in, you can run the find command:
find /home/backup -name "*abhi*"

This will list any filenames with "abhi" in them that are found in /home/backup or any sub-directory beneath /home/backup, i.e. /home/backup/dir1.

example

find /home/backup -name "*abhi*"
home/backup/dir1/abhi.dat
home/backup/abhi.dat
home/backup/abc_abhi.dat
home/backup/abc_abhi_xyz.dat

There should be manual pages installed in your UNIX server. If you type:

man find

It will give a more in-depth explanation and options.

Good Luck
