-It is normally used to clean up directories such as /tmp.
-**Checklist**
-  * Distro: Enterprise Linux 6
-----
-====== Install ======
-Tmpwatch does not come installed on a CentOS 6 minimal installation.
-<code bash>
-yum install tmpwatch
-</code>
-===== cron.daily =====
-After installation, there will now be a tmpwatch cron script in: /etc/cron.daily/tmpwatch
-See examples below for contents and explanation.
-----
-====== Tmpwatch Usage ======
-Format
-<code bash>
-tmpwatch -[options] <time> <directories>
-</code>
-**time**
-  * Threshold for removing files.
-  * Number with optional single character suffix
-    * m = minutes
-    * h = hours (default if not specified)
-    * d = days
-**directories**
-  * One or more directories specified for clean up. (Space separated)
-**Common Options**
-  * -u, --atime => Delete files based on the file's access time. (default setting)
-    * Note: the "updatedb" file system scans keep the atime of directories recent.
-  * -m, --mtime => Delete files based on the file's modification time.
-  * -c, --ctime => Delete files based on the file's inode change time. For directories, delete based on modification time.
-  * -a, --all => Remove all file types, not just regular files, symbolic links and directories.
-  * -f, --force => Remove files even if root doesn't have write. (same as rm -f)
-  * -t, --test => Don't actually remove anything.
-  * -v, --verbose => Print display.
-  * -x => Skip specified path. (if directory, skip all files inside)
-  * -X => Skip paths matching specified pattern.

-==== Fictional App in /opt ====
-  * Clean up an application's tmp directory at /opt/app/tmp
-  * Check access time (-u), modification time (-m), and change time (-c).
-  * Delete if any of the three are older than 30 days (30d).
-<code bash>
-tmpwatch -umc 30d /opt/app/tmp
-</code>
-----
-==== Default /etc/cron.daily/tmpwatch ====
-**First tmpwatch (with all the "-x")**
-  * Clean up /tmp
-  * Check access time (-u), modification time (-m), and change time (-c).
-  * Exclude all directories specified after each "-x"
-  * Exclude any directory that matches the pattern after the "-X"
-  * Delete if any of the -umc options are older than 10 days (10d).
-**Second tmpwatch "$flags" 30d /var/tmp**

-  * Delete if any of the -umc options are older than 30 days (30d).
-**Third /usr/sbin/tmpwatch "$flags" -f 30d "$d"**
