Thanks for the quick reply bakunin. I was attempting to use sed as I can make it work easily for a single file, but I was having difficulty figuring out how to run it for all files in a directory, and save the output to the same filename in a different directory.

I don't understand how your code is going to do what I want. Re-reading my original post, I may have been unclear.

For example, this is /mnt/music/playlists/madsonic/Rock.m3u8:
Code:
#EXTM3U
#EXTINF:212,Steppenwolf - Born to Be Wild
/mnt/music2/Steppenwolf/Steppenwolf/05 Born to Be Wild.flac
#EXTINF:453,Lynyrd Skynyrd - Tuesday's Gone
/mnt/music2/Lynyrd Skynyrd/The Definitive Lynyrd Skynyrd Collection/1-13 Tuesday's Gone.mp3
#EXTINF:241,Kansas - Dust in the Wind
/mnt/music2/Kansas/Always Never the Same/02 Kansas - Dust in the Wind.flac
#EXTINF:249,Journey - Don't Stop Believin'
/mnt/music2/Journey/Greatest Hits/02 Don't Stop Believin'.mp3

Each .m3u8 file in /mnt/music/playlists/madsonic has lines that start with "/mnt" which I want to simply replace with "//10.0.10.91".

Then save the new file with lines modified to /mnt/music2, keeping the file name and changing the extension to .m3u. So the above would then be located at /mnt/music2/Rock.m3u.

Thanks for helping a novice!

auto.master

AUTO.MASTER(5)							File Formats Manual						    AUTO.MASTER(5)

NAME

       /etc/auto.master - Master Map for automounter

DESCRIPTION

       The  auto.master map is consulted when the autofs(8) script is invoked to set up the necessary mount points for the automounter.  Each line
       in this file describes a mount point and points to another file describing the file systems to be mounted under this mountpoint. The access
       to those maps is governed by a key.

       Access to an automounted file system is customarily done using the path scheme:

       /mountpoint/key/path/file,

       where  the mountpoint will be listed in the auto.master configuration file. The key is matched in the map file pointed to by the master map
       (See autofs(5)).  The path and the file are referring to the file on the file system mounted.

FORMAT

       The file has three fields separated by an arbitrary number of blanks or tabs. Lines beginning with # are comments. The first field  is  the
       mount  point.  Second field is the map file to be consulted for this mount-point.  This field is of the form maptype:mapname, where maptype
       is one of the supported map types (file, program, yp, nisplus, hesiod, userdir, ldap), and mapname is the name of the map. The third  field
       is optional and can contain options to+ be applied to all entries in the map. Options are cumulative, which is a difference from the behav-
       ior of the SunOS automounter.

       The format of the map file and the options are described in autofs(5).

EXAMPLE

	 /home	   /etc/auto.home
	 /misc	   /etc/auto.misc
	 /mnt	   yp:mnt.map

       This will generate three mountpoints /home, /misc, and /mnt.  All  accesses  to	/home  will  lead  to  the  consultation  of  the  map	in
       /etc/auto.home, all accesses to /misc will consult the map in /etc/auto.misc, and all accesses to /mnt will consult the NIS map mnt.map.
