Where are you expecting it to echo to? Take a look in the syslog stuff.
Try /var/log/crond/current |

i tried this :
| Code: |
crontab -e
editing root's crontab
|
this gives me :
| Code: |
# /etc/crontab
#
# $Header: /var/cvsroot/gentoo-x86/sys-apps/fcron/files/crontab,v 1.7 2004/07/18 04:34:03 dragonheart Exp $
# fcron || dcron:
# This is NOT the system crontab! fcron and dcron do not support a system crontab.
# to get /etc/cron.{hourly|daily|weekly|montly} working with fcron or dcron do
# crontab /etc/crontab
# as root.
# NOTE: This will REPLACE root's current crontab!!
# 20 Apr 2002; Thilo Bangert <bangert@gentoo.org>
# check scripts in cron.hourly, cron.daily, cron.weekly and cron.monthly
0 * * * * rm -f /var/spool/cron/lastrun/cron.hourly
1 3 * * * rm -f /var/spool/cron/lastrun/cron.daily
15 4 * * 6 rm -f /var/spool/cron/lastrun/cron.weekly
30 5 1 * * rm -f /var/spool/cron/lastrun/cron.monthly
*/10 * * * * /usr/bin/test -x /usr/sbin/run-crons && /usr/sbin/run-crons
|
i added :
| Code: |
*/1 * * * * echo 'testing crontab'
*/1 * * * * echo testing crontab
*/1 * * * * echo -f testing crontab
*/1 * * * * echo -f 'testing crontab'
|
so it would try to echo in different ways ever 1 minute, but still im not getting any echo's in console window 
any suggestions ?
thx
Edit
trying this too:
| Code: |
*/9 * * * * cp -f /var/www/localhost/htdocs/test.delete /var/www/localhost/htdocs/crontab/test.delete
*/10 * * * * rm -f /var/www/localhost/htdocs/crontab/test.delete
|

Hi G3n2,
I had the same problem that things added into /etc/crontab didn't work.
After googling around, I found that neither dcron nor fcron support a
system-wide /etc/crontab. These deamons don't bother about the things you
insert into this file until you "copy" it to root's crontab with | Code: | | crontab /etc/crontab |
Therefore, you have to "copy" /etc/crontab over to root's crontab every time you edit this file accordingly. But be careful that you don't overwrite changes you made in root's crontab via
The only daemon in the portage tree supporting a system-wide /etc/crontab is vixie-cron AFAIK. So I recently switched from dcron to vixie-cron and everything works fine since then.
Hope this helps you a little bit.  |

xmms works only with X.
So you could do it this way:
| Code: | | 31 2 * * * export DISPLAY=:0 && xmms /songs/abd.mp3 |
...but you must be sure that X is running at 2:31 and that it got started by the same user whose crontab you've edited (root, you told ... btw: don't use root accounts to do day-by-day working).
Otherwise it will not work.
So I really think you'd better use a command line player like madplay or something... for example by adding to your 'normal user' crontab ('crontab -u <normaluser> -e')...
| Code: | | 31 2 * * * madplay /songs/abd.mp3 |

i did changes in /etc/goup file to make ordinary user in the the grp of cron
| Quote: | | cron::16:cron,anshul |
also then i change the permissions of /usr/bin/crontab to 755 so that group user can access it.
now on running
| Quote: | | crontab -u anshul -e |
it gives the following error
| Quote: | | must be privileged to use -u |
what can i do now?

Hi G3n2,
cron is not intended to "echo" something to any console, every output a cron job creates is sent via mail to
- the user who owns the cron job (variable MAILTO not set in the crontab file)
- the mail account defined in the variable MAILTO
- or no output at all if MAILTO = "" (empty value)
according to
You shold first find out where mails to root will be delivered to (AFAIK if you haven't configured anything for sending mail, they will be stored in
If you have mail delivery configured, output by crontab should be in root's mailbox.
