And please send me cron logs.

this is last log entry, and this script didnt work and i understand wat u r talking abt, but i meant to say, that if i set jobs at 18:30 hrs or 9:20 hrs, that job is also not working, so it shud not b any issue with 0 at single minutes, as other jobs are not working as well...

Would you please write down here your crontab entries and also tell how much time take your first script to complete its process.

You need to check your system process in that time when your second script running through crontab.

You can see process with many ways like (top, ps) etc. Let's try to solve your problem.

create a filed like /home/checkmycron.sh. In this file paste these lines.

Help with Code Tags

(Toggle Plain Text)

#!/bin/sh
stamp=`/usr/bin/date | awk '{print $4}'`
/usr/bin/mkdir /tmp/my_test_dir-$stamp

#!/bin/sh stamp=`/usr/bin/date | awk '{print $4}'` /usr/bin/mkdir /tmp/my_test_dir-$stamp

save the file and make it executable with this command.

chmod +x /home/checkmycron.sh

Make sure (date and mkdir) path. Because some time cron is not working without complete path.

The above script will create a file in /tmp/my_test_dir with time stamp. You just need to add this script in crontab like.

30 09 * * 3 /home/checkmycron.sh
01 14 * * 3 /home/checkmycron.sh
20 18 * * 3 /home/checkmycron.sh

On 18:20 check your /tmp/ directory there should be three files created. If you find 3 files with the time stamp as per your crontab then there is no problem with your crontab & we will do next step.
