One of my systems has a crontab like this to clean up and consolidate the output of the video monitoring app "motion":
# crontab -l # DO NOT EDIT THIS FILE - edit the master and reinstall. # (/home/grant/cron.root.txt installed on Sat Sep 25 10:42:18 2010) # (Cron version V5.0 -- $Id: crontab.c,v 1.12 2004/01/23 18:56:42 vixie Exp $) 50 23 * * * /bin/rm /home/motion/$(date -d 'yesterday' +%Y%m%d)*.jpg 55 23 * * * /bin/rm /home/motion/$(date -d 'yesterday' +%Y%m%d)*.avi 59 23 * * * /usr/bin/mencoder /home/motion/$(date +%Y%m%d)*.avi -noidx -o /home/motion/full-$(date +%Y%m%d).avi -ovc copy -oac copy If I execute each command manually, it works great, but nothing happens otherwise. Can someone tell me why this crontab doesn't seem to be executing? - Grant
