Hello, Yes, you are rigth, it´s not good reason to use that file. (but test) And (crontab -e) uses vi editor.
crontab -l looks: # DO NOT EDIT THIS FILE - edit the master and reinstall. # (Eth0Dwn installed on Mon Jan 29 17:07:59 2001) # (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $) 00 21 * * * /sbin/ifdown eth0 I tried the file with (looping ) at -f too without problems ,but I like that crontab is, at this case, more useful than at. thank you, Justin Timo > But when I try start with file > crontab Eth0Dwn > starts job, but nothing else happend.
