Im trying to use mergecap to merge 15 old pcap files in a folder. I tried to use
FILES=($(find /mnt/md0/capture/DCN/ -maxdepth 1 -type f -name "*.pcap" -print0 | xargs -0 ls -lt | tail -15 | awk '{print $8}'))
and use mergecap command as mergecap -w Merge.pcap ${FILES[@]}
but the mergecap doesnt run when I put it on crontab. Is there any method to combine these two commands to work properly.
Does it run from the CLI? – MariusMatutiae – 2014-02-06T12:41:14.373
yes, it works from terminal perfectly.. and I checked all path in the crontab, everything is fine, In syslog it shows that a mail is send just after execution. – Jishnu U Nair – 2014-02-06T12:48:28.427
are you running the crontab as root, or as normal user? – MariusMatutiae – 2014-02-06T12:51:35.223
normal user. But I have put the script in sudo crontab -e – Jishnu U Nair – 2014-02-06T12:55:37.447
try switching the script to the normal user's crontab. Or, alternatively, leave the script in sudo's crontab, but debug it as sudo. The two options are distinct, you should try both of them. – MariusMatutiae – 2014-02-06T12:58:01.500
You're not quoting
"${FILES[@]}"
? – terdon – 2014-02-06T15:47:59.673@terdon In the mergecap command? no i dint quote – Jishnu U Nair – 2014-02-06T20:10:13.420
I've never used mergecap but that might be a possible problem, you should always quote shell variables when expanding, just in case (see suspectus's answer). – terdon – 2014-02-06T20:14:13.207
