help in script

Anish Kumar — Thu, 24 Jun 2010 12:16:12 GMT

Hi Experts,

please help me on this

If i run this command
ovtopodump -lr |awk '/INTERFACE DESCRIPTION/

The o/p will be like this

INTERFACE DESCRIPTION: Loopback0
INTERFACE DESCRIPTION: Loopback1
INTERFACE DESCRIPTION: Serial0/2/0:0
INTERFACE DESCRIPTION: FastEthernet0/1

I need to automate this command
1. should be taken from a file
2. INTERFACE DESCRIPTION should be compared, if yes then command should be executed.

Cheers!

Hi:

To run a command with a list as you are asking could look something like:

# cat ./myrun
#!/usr/bin/sh
while read HOST
do
echo "HOST=${HOST}"
ovtopodump -lr ${HOST}|awk '/INTERFACE DESCRIPTION/'
done < ./myhosts
exit 0

...where the 'myhosts' file has lines of server hostname's, one per line.

You said:

> INTERFACE DESCRIPTION should be compared, if yes then command should be executed.

Compared to what? and what should be executed?

Regards!

Hi Kumar

Script right by Fergunson should work

Another option:

for i in `/tmp/myhost`
do
ovtopodump -lr $i|awk '/INTERFACE DESCRIPTION/'
done

Regards.

Hi Nightwatch,
>>for i in `/tmp/myhost`

It should be like this you forget the "cat"

for i in `cat /tmp/myhost`
do
ovtopodump -lr $i|awk '/INTERFACE DESCRIPTION/'
done

Or just toss the cat:
for i in $(< /tmp/myhost); do
