The next thing I would do is to attach strace to cron just before it kicks off. Make sure to capture the output - there will be a lot of it. strace -p PIDofCron -f -o/path/somefile You might also look at the cron file with an octal editor to make sure there are no funny characters in it. Or just create a brand new one. I would also look carefully each directory in the path and the contents of them as well i.e. ls -ld /home ls -la /home ls -ld /home/statsman ls -la /home/statsman ls -ld /home/statsman/stats ls -la /home/statsman/stats -Mark > > Piped the cron commandline to a file crondebug as mark suggested, its > created at cron run time, but empty. > 36 13 * * * > >/home/statsman/stats/crondebug > > For the first line of the run_stats.sh (tried also with #!/bin/bash) > file it calls I added > > echo "stage 1" >> /home/statsman/stats/gendebug > > Run it manually from console it echos stage 1, (also echo stage 2 I > added, then after that the perl script is invoked) fine. > > Run from cron it never even does the echo "stage 1" to the file (or at > least doesn't create it). > > So it looks like its either dying on execing the file and not getting > any further as it never writes the first line of the simple bash script > or not even trying to call the file?
