logcmd - Log the output of a program.
logcmd [options] -- <command> [command-args ...]
logcmd logs the output of a program. This program is useful for logging program output for programs that do not have a built-in logging facility.
Typical usage is to use logcmd in crontabs to log any command output to a file instead of mail automatically being sent to the crontab owner.
When invoking logcmd, you must use ``--
'' to separate the
logcmd and its options from the command you are invoking. For
example,
logcmd -log out.log -- some-cmd arg1 arg2 arg3
This tells logcmd to run ``some-cmd arg1 arg2 arg3
'' and have
any output goto out.log
.
Each line logged will be preceded by a timestamp, the process ID, and the name of the command. Also, before the first log message for a command is printed, logcmd will print out a line giving the full command-line of the command invoked. Example:
[2002-07-30 14:52:13] [25392] logcmd: Command: [25393] mhonarc -quiet -out out /var/archiver/mail [2002-07-30 14:52:13] [25393] mhonarc: [2002-07-30 14:52:13] [25393] mhonarc: Warning: Unrecognized character set: utf-8 [2002-07-30 14:52:13] [25393] mhonarc: Message-Id: <1022714308.2028.1.camel@xxx.xxx.xxx> [2002-07-30 14:52:13] [25393] mhonarc: Message Number: 00367 [2002-07-30 14:52:13] [25393] mhonarc: [2002-07-30 14:52:13] [25393] mhonarc: Warning: Unrecognized character set: utf-8 [2002-07-30 14:52:13] [25393] mhonarc: Message-Id: <1022716087.2028.3.camel@xxx.xxx.xxx> [2002-07-30 14:52:13] [25393] mhonarc: Message Number: 00368 [2002-07-30 14:52:14] [25393] mhonarc: [2002-07-30 14:52:14] [25393] mhonarc: Warning: Unrecognized character set: utf-8 [2002-07-30 14:52:14] [25393] mhonarc: Message-Id: <1024365245.9394.0.camel@xxx.xxx.xxx> [2002-07-30 14:52:14] [25393] mhonarc: Message Number: 00398
