Saving the output of unattended scripts
I put this into all of my unattended scripts:


Code:
# Send all output to a logfile and supress input
typeset LOG="/tmp/${0##*/}.out"
mv $LOG ${LOG}.old >/dev/null 2>&1
[[ -t 1 ]] && echo "Writing to logfile '$LOG'."
exec > $LOG 2>&1
exec < /dev/null 2<&1


All stdout and stderr will be logged. Also, since stdin is closed, the script won't hang if any commands wait for input. It will report the logfile name to stdout if run from the command line (attached to a terminal).

This should essentially work the same as the redirection code offered above. If neither is working then something else is wrong, and you'll need post more info about the error.

procmeter3-log

PROCMETER3-LOG(1)					      General Commands Manual						 PROCMETER3-LOG(1)

NAME

       procmeter3-log - A system monitoring / logging program.

SYNOPSIS

       procmeter3-log [-h|--help] [--rc=<filename>] [--...]  [...]

DESCRIPTION

       ProcMeter  Displays one or more pieces of information about the operating system and other resources.  Most of the information that is dis-
       played comes from the /proc filesystem.	The program is modular and very configurable.

OPTIONS

       The command line options are described below.

       -h     Provides a help message listing the available outputs.  This will be different for different computers depending on the Linux kernel
	      version that is being used and the hardware/software that is configured.

       --rc=<filename>
	      Load the specified .procmeterrc file in stead of the searching in the usual places.

       --...  A  list  of  configuration file options that will override the values in the .procmeterrc file.  The format of these options is (for
	      example) --library.path=/usr/local/procmeter3 which is equivalent to the entry in the .procmeterrc file of

	       [library]
	       path = /usr/local/procmeter3

	      All spaces around the equal sign must be removed and if spaces are required in the value on the right hand side then quotes must	be
	      used around the entire command line option.

       ...    A  list  of  names of outputs that are to be displayed.  This can include any of the outputs that are available (see the -h option).
	      For the CPU usage is in a module named Statistics with an output named CPU and there are graph (-g), text (-t) and bar (-b) options.
	      Since this version of the program does not display anything, but logs the data to a file it does not matter which one is chosen.	To
	      store the CPU usage data you would use the command line option Statistics.CPU-t

USAGE

       When started the program will log all of the requested information on the standard output (stdout).  The outputs  that  are  displayed  are
       those from the command line and those from the .procmeterrc configuration file.

MODULES

       The modules that are available for procmeter3-log are described in the procmeter3_modules(1) manual page.
