 L.CMDS 5 ""
C 6  NAME
L.cmds - UUCP remote command permissions file
 DESCRIPTION
The
 L.cmds file contains a list of commands, one per line, that are permitted
for remote execution via
 uux (1C).
The default search path is /bin:/usr/bin:/usr/ucb. To change the path,
include anywhere in the file a line of the form:

 PATH=/bin:/usr/bin:/usr/ucb


Normally, an acknowledgment is mailed back to the requesting
site after the command completes. If a command name is suffixed with
 ,Error , then an acknowledgment will be mailed only if the command fails.
If the command is suffixed with
 ,No , then no acknowledgment will ever be sent. (These correspond with
the
 -z and
 -n options of
 uux , respectively.)

For most sites,
 L.cmds should only include the lines:

 rmail
 ruusend


News sites should add:

 PATH=/bin:/usr/bin:/usr/ucb:/usr/new
 rnews,Error


While file names supplied as arguments to
 uux commands will be checked against the list of accessible directory trees in
 USERFILE (5), this check can be easily circumvented and should not be depended upon.
In other words, it is unwise to include any commands in
 L.cmds that accept local file names. In particular,
 sh (1) and
 csh (1) are extreme risks.

It is common (but hazardous) to include
 uucp (1C) in
 L.cmds ; see the NOTES section of
 USERFILE .  FILES
