WérnyúlMindig annak a felhasználónak a nevében aki éppen futtatja, ha külön nincs megadva. A crontabnak a manjában pedig egy [ -u user ] kapcsoló, hogy meg lehessen adni kinek a nevében szeretnéd futtatni.
A man crontab-ból egy pár részlet:
NAME
crontab - maintain crontab files for individual users (Vixie Cron)
SYNOPSIS
crontab [ -u user ] file
crontab [ -u user ] [ -i ] { -e | -l | -r }
...
If the -u option is given, it specifies the name of the user whose crontab is to be used (when listing) or modified (when editing). If this option is not given, crontab examines "your" crontab, i.e., the crontab of the person executing the command. Note that su(8) can confuse crontab and that if you are running inside of su(8) you should always use the -u option for safety's sake.
...
The -e option is used to edit 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. If neither of the environment variables is defined, then the default editor /usr/bin/editor is used.
