Code:
cat /etc/crontab

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root

# For details see man 4 crontabs

# Example of job definition:
# .---------------- minute (0 - 59)

I am getting the below message.
I have setup the same by giving crontab -e. but the script is not executing it.
Code:
 cat /etc/crontab
cat: Cannot open /etc/crontab: No such file or directory

---------- Post updated at 08:40 AM ---------- Previous update was at 07:41 AM ----------

please find my test below.
Code:
cat test.sh
#!/bin/ksh
date > /tmp/kk.txt


Code:
crontab -l | grep "test.sh"
39 * * * * ./tmp/test.sh

But this doesn't work

Dont use relativ paths within crontab, use absolute paths instead. (as in your initial post)

hth

EDIT:
Or add the PATH env to crontab, put the script in such a path and just execute the script. (so the theory)
Either way, you have to make sure the script has execution flag set.

I am not sure how to add the PATH env to crontab ?

How to set the flag set ?

Please help me out.

1. Use crontab -e to add something like:
Code:
PATH=/path/to/:/usr/bin:/bin:/sbin

2. As for the execution flag:
Code:
chmod +x ./script.sh

However, i recomend to just use the full path in crontab!

@sea: full path not only in crontab, but in the script itself as well.

@ramkumar15: "doesn't work" doesn't help. Be specific: did it start? If yes, did crash? If no, any output? any error msgs? filed? mailed?

@sea (post #2) that's a root crontab entry. Normal users' crontabs don't have the username.
