We are decent with scripting language bash and not now hot to remove older files for example 1 day. rm command do not have this type of option to use easily. I think adding this type of feature make a lot of system administrators more happy.

Remove Older Than 1 Day

We will use following find command example which is explained in detail below.

$ find /tmp -mtime +1 -type f -name '*.tmp' -delete

• find is the command we use
• /tmp is the directory where files resides
• -mtime provide time option and +1 means older then one day
• -type provides file types here we set file but we can use directory, socket etc
• –name ‘*.tmp’ filters files according to their names. we just want tmp extension files
• And the magic resides here -delete will delete the files matching provided criteria

Remove Older Than 1 Week

We can use the same script in order to remove files with extension tmp from /tmp directory with the following script. As a week is 7 days we can use +7 to specify a week like below.

$ find /tmp -mtime +7 -type f -name '*.tmp' -delete

Remove Older Than 1 Month

We can use the same script in order to remove files with extension tmp from /tmp directory with the following script. As a month is 30 days we can use +30 to specify a week like below.

$ find /tmp -mtime +30 -type f -name '*.tmp' -delete
