Cron entry

Prashant Zanwar_4 — Tue, 12 Jul 2005 07:16:34 GMT

00 3 * * 1-6 /usr/tools/mcsg/package_check ip_ecust "$(/usr/local/tools/backup/ecprd-bcv_online_merge_split) && $(/usr/local/tools/backup/ecprd-rdf_merge_split)" >/var/log/backup_ecustomer.log 2>&1

While I put above entry, part after && is skipped? any clue?
Thx

There are 2 separate commands.
Can you combine them?

No cant combine those.

This is basically a backup job. 2nd depends on 1st.
R1 > R1/BCV > R2. It has to be that way. SO please let me know any way to do it.
Thx

Combine them into a single shell script with the command "wait" separating the two main commands. That will ensure the system waits for the first command to finish before it runs the second.

If there is a dependency, have the 1st part of a script return a value and if that value is successful then execute the 2nd part.

one suggestion might be to enclose using open-braces to the shell:

package_check_ip_ecust ( x && y ) > outfile.

my thinking is, if you can type this in the shell, it might do the trick via cron line, too. Example: type-in at your prompt:

( date && date )

Hi,

You can use the "serialize" command to run one processe after another. Check the man pages.

Enjoy :-)

I don't think you can do it that way...

For example, when I:

3,8,13,18,23,28,33,38,43,48,53,58 * * * * [ -d /var/adm/lp/XEBEC ] && /usr/local/bin/mrtg-stats >/dev/null 2>&1

It will only execute after the && if /var/adm/lp/XEBEC exists...

The && is a conditional - and you are not providing a condition...
