deleting lines from file

NAME
sieveshell - remotely manipulate sieve scripts SYNOPSIS
sieveshell [--user=user] [--authname=authname] [--realm=realm] [--password=password] [--exec=script] [--execfile=file] server[:port] sieveshell --help DESCRIPTION
sieveshell allows users to manipulate their scripts on a remote server. It works via MANAGESIEVE, a work in progress. The following commands are recognized: list list scripts on server. put <filename> upload script to server. get <name> [<filename>] get script. if no filename display to stdout delete <name> delete script. activate <name> activate script. deactivate deactivate all scripts. OPTIONS
-u user, --user=user The authorization name to request; by default, derived from the authentication credentials. -a authname, --authname=authname The user to use for authentication (defaults to current user). -r realm, --realm=realm The realm to attempt authentication in. -p password, --password=password The password to use when authenticating to server. Note that this parameter can be seen in the process list. Use with caution! -e script, --exec=script Instead of working interactively, run commands from script, and exit when done. -f file, --execfile=file Instead of working interactively, run commands from file file and exit when done.
