atcronsh(ADM)

atcronsh -- at and cron administration utility

Syntax

/usr/lib/sysadm/atcronsh

Description

atcronsh is the screen interface invoked by the Cron Manager. It is used to specify users allowed to use the cron(C), at(C) and batch (see at) commands. It also allows the at and batch prototype files to be edited.

The program allows a system default for cron , at and batch to be given. The defaults can be:

none: no user authorized
allow: all users allowed to use the commands unless a user is specifically denied
deny: all users denied to use the commands unless a user is specifically authorized

The default setting decides whether an allow or deny file is to be used (deny file means /usr/lib/cron/cron.deny or at.deny, allow file means /usr/lib/cron/cron.allow or at.allow).

For each user (unless the none system default has been chosen), a specific authorization for cron, at and batch may be given. The allow and deny files are interpreted as follows:

if an allow file exists, and the user name appears in it, the user is allowed access
if an allow file exists, access is denied
if a deny file exists and the user name appears in it, access is denied
if a deny file exists, access is allowed
access is denied

Limitations

Invoking atcronsh is not recommended; use the Cron Manager.
