flow-expire

flow-expire(1)						      General Commands Manual						    flow-expire(1)

NAME

       flow-expire -- Manage storage of flow file archives by expiring old data.

SYNOPSIS

       flow-expire [-h]  [-d debug_level]  [-e expire_count]  [-E expire_size] -w workdir

DESCRIPTION

       The flow-expire utility will remove the oldest flow files in a directory based on either a count of files or space utilization.	The direc-
       tory is recursively searched for flow files.  Files that do not have a flow-tools signature will be ignored.   The  internal  timestamp	is
       used  so backups or copies of the flow files that do not retain the original timestamp will not impact the operation of flow-expire.  flow-
       expire is typically used to manage storage in a distributed environment where flows are collected on  a	different  server  than  they  are
       archived.

OPTIONS

       -d debug_level
		 Enable debugging.

       -e expire_count
		 Retain the maximum number of files so that the total file count is less than expire_count.

       -E expire_size
		 Retain the maximum number of files so that the total storage is less than expire_size.  The letters b,K,M,G can be used as multi-
		 pliers, ie 16 Megabytes is 16M.

       -h	 Display help.

       -w workdir
		 Work in workdir.

EXAMPLES

       Remove the oldest flow files in /flows/krc4 until the total storage is less then 2 Gigabytes.

	 flow-expire -E2Gig -w /flows/krc4

       Remove the oldest flow files in /flows/krc4 until the total number of files is less then 100.

	 flow-expire -e100 -w /flows/krc4

BUGS

       Empty directories are not removed.
