I am facing a strange issue while running a script(eg A) from the crontab entry
the script calls one more script(eg B) within it
now when i run the script A manually(with nohup) it also executes the script B (embedded inside it) as expected.
but when i run the script A from the crontab entry it runs the script A,
it also executes all the statements above and below the call to script B
but does not executes script B
Please Advice and let me know if more details are needed
is this a root crontab?
what file permisions do you have on file A and file B.
yes the crontab is root and i am having 777 file permissions for both
777 is bad for security but good for de-bugging 
are you calling file B with full path?
or assumeing a PATH has been set?
The script B lies in /xyz/abc directory
i am changing the directory to /xyz/abc in script A
and then calling the script B
please post both scripts so we don't need to guess.
I would bet for a path problem as suggested above. The best way to troubleshoot a cron problem is to redirect the STDERR to a file or active TTY:
* * * * * /full/path/to/script 2> /tmp/cron_err
Thanks!! indeed it turned out to be a PATH issue,
I gave the full path in the script A to call script B and it worked.
Although just curious why changing to the directory to place of script B didn't worked.
