-:::Don't understand this small script:::-

Here is the crontab entry:-

Code:

bash-3.00$ /usr/local/bin/sudo crontab -l sysmgr
Password:
00 02 * * 1     /usr/local/bin/sudo /opt/SUNWexplo/bin/explorer -P -q # SUNWexplo
45 02 * * 1     /usr/local/bin/sudo /users/sysmgr/ios  
45 02 * * 1     /usr/local/bin/sudo  find /opt/SUNWexplo/output/ -name  "explorer*`uname -n`*" -exec chmod -R 755 {} \; > /dev/null 2>&1
59 02 * * 1     scp -q /opt/SUNWexplo/output/*.tar.gz 10.10.10.12:/opt/lisa/explorers/ 2>&1|nawk '! /^$|^\*/'
00 06 * * *     /usr/local/bin/sudo /usr/sbin/fmadm faulty -a

My question is when I run this /usr/local/bin/sudo /users/sysmgr/ios on command line only this diplays as output
/opt/SUNWexplo/output/explorer.844d540d.Server1-2013.09.16.00.00/disks

But when I execute it second time then all outputs comes.

this what you need:-

Code:

-bash-3.00$ ls -l explorer.844d540d.amspdmbep31-2013.09.16.00.00/disks
total 708

here is the reason :

the first line mentioned above is actually producing the single line output and the long output that you are getting is because of the second line that is executing in parallel to the first one.

EDIT:
Try running this command [CODE /usr/local/bin/sudo /users/sysmgr/ios[/CODE] in a seperate terminal and observe the output.

manalisharmabe · 09-17-2013, 04:48 AM

yes, Thanks for reply.
I dont think the problem is with second line.

I am talking only about below output:-

Code:

bash-3.00$ /usr/local/bin/sudo /users/sysmgr/ios

/opt/SUNWexplo/output/explorer.844d540d.server1-2013.09.16.00.00/disks

In red line it just produces one line output but in second blue line it produces big output only on command line
This what I want to know WHY SO?
Why in the second attempt the same command produces big output?

Thanks.

you may try to insert set -xv at the beginning of the script and you will see what's happening

Thanks for reply!

What xv means? v for verbose, but x ?

Are you saying like this

Code:

/usr/local/bin/sudo -xv /users/sysmgr/ios

or

Code:

/usr/local/bin/sudo /users/sysmgr/ios -xv

?

Thanks.

manalisharmabe · 09-17-2013, 10:04 AM

[QUOTE=manalisharmabe;5029234]Thanks for reply!

ok like this

set -xv ?

I will try it.

thanks.

pan64 · 09-17-2013, 10:51 AM

no, you need to edit the script and add this line:
#!/usr/bin/bash
set -xv

or if it does not work you can execute it as:
sudo bash -xv /users/sysmgr/ios

-v verbose, -x debug info

manalisharmabe · 09-17-2013, 12:16 PM

I will get back to this shortly.
