Redirecting Error Output

Hi can someone please guide me on how to redirect the standard error of a script into a file?

This is an example of a cron job that redirects standard output and standard error of a script to a file called archive_backup.

#Archive Backup Log
01 7 1 * * /bin/bash -v /mnt/nfs-f13-live/my_scripts/archive_backup_log >>/home/bill/archive_backup.log 2>&1

one more question :

how can i set error redirection within the script. i do not want to write scriptname.sh 2>error.log ,i just want to run the script normally like ./scriptname & want errors to be redirected in a file.Thanxx beforehand.

For the errors to be trapped within the script you must write the redirects in the script and designate the error file. That way when you run your ./scriptname the errors generated within the script will be piped to the error file.
