You can use find with the -exec flag for this.

For example in Linux:

Code:

find /path/to/files* -mtime +30 -exec rm {} \;

Note that there must be spaces between rm, {} and \;

More Explanation:

The first argument is the path to the files you want to delete. This can be a path, a directory, or a wildcard as in the example above. I would recommend using the full path, and make sure that you run the command without the exec rm to make sure you are getting the right results.

The second argument, -mtime, and this switch is used to specify the number of days old that the file is. If you enter +30, it will find files older than 30 days.

The third argument, -exec, allows you to pass in a command such as rm. The {} \; at the end is required at the end the of the command.

NOTE:

Do not run this without testing it first... for example. always run first and look at the output, for example:

Code:

find /path/to/files* -mtime +30  > /tmp/testing_123.txt

After you are happy it is working as you wish, then you can run it.. but honestly, here is what I do:

Code:

mkdir /tmp/files_to_delete
find /path/to/files* -mtime +30 -exec mv {} /tmp/files_to_delete \;

Better to move first and delete later!!! ALWAYS

Get in the very good habit of moving files before you delete them, especially using scripts where one fat finger mistake can ruin your day!

pwd

pwd(1T) 						       Tcl Built-In Commands							   pwd(1T)

__________________________________________________________________________________________________________________________________________________

NAME

       pwd - Return the absolute path of the current working directory

SYNOPSIS

       pwd
_________________________________________________________________

DESCRIPTION

       Returns the absolute path name of the current working directory.

EXAMPLE

       Sometimes it is useful to change to a known directory when running some external command using exec, but it is important to keep the appli-
       cation usually running in the directory that it was started in (unless the user specifies otherwise) since that minimises  user	confusion.
       The way to do this is to save the current directory while the external command is being run:
	      set tarFile [file normalize somefile.tar]
	      set savedDir [pwd]
	      cd /tmp
	      exec tar -xf $tarFile
	      cd $savedDir
