Alternatively, a single regex could be used with the substitution operator like so -

Code:

$ cat f8

htcacheclean

HTCACHECLEAN(8) 						   htcacheclean 						   HTCACHECLEAN(8)

NAME

       htcacheclean - Clean up the disk cache

SYNOPSIS

       htcacheclean [ -D ] [ -v ] [ -t ] [ -r ] [ -n ] -ppath -llimit

       htcacheclean [ -n ] [ -t ] [ -i ] -dinterval -ppath -llimit

SUMMARY

       htcacheclean  is  used  to keep the size of mod_disk_cache's storage within a certain limit. This tool can run either manually or in daemon
       mode. When running in daemon mode, it sleeps in the background and checks the cache directories at regular intervals for cached content	to
       be removed. You can stop the daemon cleanly by sending it a TERM or INT signal.

OPTIONS

       -dinterval
	      Daemonize  and  repeat  cache  cleaning every interval minutes. This option is mutually exclusive with the -D, -v and -r options. To
	      shutdown the daemon cleanly, just send it a SIGTERM or SIGINT.

       -D     Do a dry run and don't delete anything. This option is mutually exclusive with the -d option.

       -v     Be verbose and print statistics. This option is mutually exclusive with the -d option.

       -r     Clean thoroughly. This assumes that the Apache web server is not running (otherwise you may get garbage in the cache).  This  option
	      is mutually exclusive with the -d option and implies the -t option.

       -n     Be  nice. This causes slower processing in favour of other processes. htcacheclean will sleep from time to time so that (a) the disk
	      IO will be delayed and (b) the kernel can schedule other processes in the meantime.

       -t     Delete all empty directories. By default only cache files are removed, however with some configurations the large number of directo-
	      ries  created  may  require attention. If your configuration requires a very large number of directories, to the point that inode or
	      file allocation table exhaustion may become an issue, use of this option is advised.

       -ppath Specify path as the root directory of the disk cache. This should be the same value as specified with the CacheRoot directive.

       -llimit
	      Specify limit as the total disk cache size limit. The value is expressed in bytes by default (or attaching B to the number).  Attach
	      K for Kbytes or M for MBytes.

       -i     Be  intelligent  and  run  only  when  there was a modification of the disk cache. This option is only possible together with the -d
	      option.

EXIT STATUS

       htcacheclean returns a zero status ("true") if all operations were successful, 1 otherwise.
