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?

UNDOCUMENTED(7) Linux Programmer's Manual UNDOCUMENTED(7) NAME
undocumented - No manpage for this program, utility or function. DESCRIPTION
This program, utility or function does not have a useful manpage. Before opening a bug to report this, please check with the Debian Bug Tracking System (BTS) at <http://bugs.debian.org/> if a bug has already been reported. If not, you can submit a wishlist bug if you want. If you are a competent and accurate writer and are willing to spend the time reading the source code and writing good manpages please write a better man page than this one. Please contact the package maintainer and copy man-pages@qa.debian.org in order to avoid several people working on the same manpage. Even if you are not an accurate writer, your input may be helpful. Writing manual pages is quite easy, the format is described in man(7). The most important and time-consuming task is to collect the information to be put in the new manpage. DIAGNOSTICS
It is possible that the man page for the command you specified is installed and that your manual page index caches are out of sync. You should try running mandb(8). Try the following options if you want more information: foo --help, foo -h, foo -? info foo whatis foo, apropos foo dpkg --listfiles foo, dpkg --search foo locate '*foo*' find / -name '*foo*' Additionally, check the directories /usr/share/doc/foo, /usr/lib/foo. The documentation might be in a package starting with the same name as the package the software belongs to, but ending with -doc or -docs. If you still didn't find the information you are looking for you might consider posting a call for help to debian-user@lists.debian.org. SEE ALSO
