question on expect language

javier_ccs · 01-09-2006, 08:10 AM

hi guys,

i'm making a backup on the configuration of a juniper firewall and i'm using expect to create a script to handle it, but since i started to work with expect for the first time last saturday i hope i could get some help with it...

1. i would like to know how can i create a text file to save the output of a command?
ex: save the output of ping linux.org

Code:

>ping linux.org
From 192-168-127-red5.javier.com.ve (192.168.127.5): icmp_seq=1 Redirect Host(New nexthop: 192-168-127-red1.javier.com.ve (192.168.127.1))
64 bytes from linux.org (198.182.196.48): icmp_seq=1 ttl=49 time=124 ms

2. how can i make this script to run for example every 5th of the month? (ex: januaty 5, february 5, etc.)

i really would apreciate your help...

1) To save the output of a command to a text file, pipe the command to a file, i.e.

ping linux.org > /path/to/filename.txt
ping linux.org 1> good_output.txt 2>errors_only.txt

where "1" will specify only program output sent to stdout, and 2 specifies only output sent to stderr. See here for more information.

2) look into 'cron' and the 'crontab' file. The man page can help you there, as can searching for crontab here on LQ.

HTH!
