L.CMDS(8)L.CMDS(8)NAMEL.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(1).
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(1) in L.cmds;
see the NOTES section of USERFILE.
