Using TRAP command

Shell Programming and Scripting
1

I'm using the trap command to capture any signals received whilst my script is running.

How's the best way of writing the signal and any other error messages to a file/error log' without having to type '2>$1' on the command line after the script name?

Cheers

Hi
depends..

I use the logger command (it logs to syslog). It depends on what kind of error checking your script has..

output everything to a file is the simplest way..

You could use the special command: "exec" to redirect stdout and stderr, e.g. if you put this at the top of your script ....

exec > /tmp/logfile$$ 2>&1

... all messages will go to the log file.

From man ksh...
