Hi, all! I would like to know if it is possible to add new task for crontab from command line? For example I could do: #echo ''0 15 * * * some_command_to_execute'' >> //var/spool/cron/crontabs/root But how it could be for simple, not super-user? Thanx, Lekha

There''s a crontab command. Use sudo to alter root''s crontab.

Yes, $crontab -e will put me in vi mode. Problem that I should put command from file to cron tasks. C++ programm will read & prepare cron style string, but how to put this string into cron?! I have no ideas Lekha #### Share this post ##### Link to post ##### Share on other sites Guest Anonymous Poster quote: Original post by Vasialek Yes,$crontab -e will put me in vi mode.

Oh, and following up to myself - on non-Debian systems that''ll add a copy of the "DO NOT EDIT THIS FILE" header every time it''s run. If you''re on a non-debian system, a "| tail +4" placed somewhere in that command line might be helpful.
