hi !!
I need to use crontab to download a file and overright older file in my RH box

the ftp site is: f tp://212.199.10.11/Panda/PavSig/Pav.sig

and the file in my box sites in /usr/lib/panda/Pav.sig

what is the command to enter in crontab to do this ?


thanks very much !!!

Well first create the script to run the wget command. You could do something simple to remove the existing file first and then download the latest files with something like this:
Save and make it executable with chmod +x <scriptname>

You will want to check the man pages for wget, I can't remember exactly but I think the command I gave above in the script should just download that one file, instead of grabbing all the links, creating the directories, etc.

Then in crontab you can just do this:

0 22 * * * /path/to/script

That would envoke the script to run every day at 10pm every day and every month.

You could or can also just add the wget command in crontab to grab the file, not sure if there is a overwrite option for wget, I'd check the man pages on:

wget
crontab
cron

For more details or options. Hope this helps get you started. I'm sure there are easier ways maybe, I'm just going out of my head right now..

thanks very much

whan I write the script in vi -what it the file expention that I need to set to this file in order it to be excutble?

thanks

Just copy and paste if you want. Save it then execute the chmod command to set the permissions.

You can name it whatever you want.

chmod +x <name of script>

I would test that wget command first though to see whether or not if downloads it correctly, etc.

A bash script doesn't need any extensions like .txt or .doc

All you need is the name you choose to call it like maybe test

If you want to run that bash script called test then change to the directory and use the command: sh test

Note that if you read the wget manpage then you probably don't even need to write a script.
