EDRC/ECRONTAB

NAME

SYNOPSIS

ecrontab [-T] <file | ->

ecrontab [-u user] <-l | -r | -e> [-i] [-s]

ecrontab -V

DESCRIPTION

Prior to editing a crontab table it is automatically saved using vsav(1).

Scheduling cron jobs with ecrontab can be allowed or disallowed for different users. For this purpose, use the edrc/etc/cron.allow and edrc/etc/cron.deny files. If the cron.allow file exists, a user must be listed in it to be allowed to use crontab. If the cron.allow file does not exist but the cron.deny file does exist, then a user must not be listed in the cron.deny file in order to use ecrontab. If neither of these files exist, then only the super user is allowed to use ecrontab.

The temporary directory can be set in an environment variable. If it is not set by the user, the /tmp/ directory is used.

When listing a crontab on a terminal the output will be colorized unless an environment variable NO_COLOR is set.

OPTIONS

-u

Specifies the name of the user whose crontab is to be modified. If this option is not used, ecrontab examines "your" crontab, i.e., the crontab of the person executing the command. If no crontab exists for a particular user, it is created for them the first time the ecrontab -u command is used under their username.

-T

Test the crontab file syntax without installing it. Once an issue is found, the validation is interrupted, so this will not return all the existing issues at the same execution.

-l

Displays the current crontab on standard output.

-r

Removes the current crontab.

-e

Edits the current crontab using the editor specified by the VISUAL or EDITOR environment variables. After you exit from the editor, the modified crontab will be installed automatically.

Be aware, that the configuration file is saved automatically before editing using the vsav(1) command internally. Therefore when a messed-up file was saved, or to check changes, the vls(1), vdiff(1), vrestore(1) etc. commands can be used to verify changes or revert to a previous version.

-i

This option modifies the -r option to prompt the user for a 'y/Y' response before actually removing the crontab.

-s

Appends the current SELinux security context string as an MLS_LEVEL setting to the crontab file before editing / replacement occurs - see the documentation of MLS_LEVEL in crontab(5).

-V

Print version and exit.

CAVEATS

The files cron.allow and cron.deny must be readable by the user invoking crontab. If this is not the case, then they are treated as non-existent.
