Meaning of "find /backup/ -name '*.gz' -mtime +2 -print -exec rm {} \;"

[ran_sushmi]

I had a doubt with what the following kind of statement is going to accomplish. The statement is:-

--------------------------------------------------------------------------------------

find /backup/ -name '*.gz' -mtime +2 -print -exec rm {} \;

--------------------------------------------------------------------------------------

As per, my understanding, it is going to check in '/backup' path for all the files ending with 'gz' which were modified more than 48 hrs ago. Is, my understanding correct?

I hope, my question is clear.

Please, help in solving the doubt.

yes,you are almost correct,

find /backup/ -name '*.gz' -mtime +2 -print -exec rm {} \;

let's split this command

find /backup/

this will check for files under specified directory (which is backup)

with find you can use plenty of options check "man find"

here

-name '*.gz'

is used to retrieve all files which as .gz as extentsion.

-mtime +2

tells to get files that are last modified 2 days ago.

-print option will display the file name

find is very powerful command especially when it's used along with

-exec

with -exec you can specify the action that needs to be taken on each retrieved fiiles

here you using rm command , so it will delete files..

Above command will delete .gz files from /backup which are older than 2 days .
