UNIX for Dummies Questions & Answers

Hi

I need to schedule some tasks on AIX.

At first I must copy files from folder on second AIX server to my primary server. This job schould be done in 1 hour intervals. I want to get only new files.

Second script is needed for old files cleaning. It is necesary to delete files older than 7 days from disk, once a day at night.

I know it is very simple, could you give me some tips?

Regards,

For the copy you should consider rsync. It's not part of the standard AIX OS, but there are some Power compiled RPM's out there which you could use.

For the deletion a simple find command should do the trik. Something like:

"find /[directory] -atime +7 -exec \rm -f {} \;

Thank You for reply!

I used wget for files download:
wget -a abc.log -r -np -c -nc -nd ftp://userass@server/path/to/files

In delete script I used:
find . -mtime +7 -exec rm {} \;

Everything works great!

I have one more question. How, on AIX, i can automatically run script on system startup and shutdown?

Using /etc/inittab. There you can define that something shuld run at each runlevel. The default runlevel for AIX is 2. Therefor you can insert something like this:

ScriptAtBoot:1nce:[path to script and parameters]

Define runlevel 1 because to get to runlevel 2 the computer must pass runlevel 1. The keyword once ensures that the script only runs once.

For the system shutdown you would do:

ScriptAtShutdown:0nce:[path to script and parameters]

If you would want the script to run also when reboot happens include runlevel 6 in your definition.
