pinging


i need to ping a lot of ip-s. have to find dead ones and check for speed. now i manually use
ping -c 1 ip
for every ip and this takes a long time. i would like to be able to list the ip-s in a file and somehow do it automatically. is there a way?
using suse9.1

Create a file with all your IPs - one per line.

You can then enter the following at the command line, or put it in a script and run it:

for x in `cat [IP_FILENAME]`
do
ping -c 1 $x >> iplist
done

Where [IP_FILENAME] is the name of file with all your IP addresses. This will write the output for each ping to a file called 'iplist' this will be created in whatever directory you are in.

You need to type:

for x in `cat /home/delos/down/ipz` [CR]
do [CR]
ping -c 1 $x >> iplist [CR]
done [CR]

When [CR] is a carriage return (press the return key)

i managed to figure this out but i still have some problems, just different ones.

Quote:
delos@linux:~/down> for x in 'cat /home/delos/down/ipz'
> do
> ping -c 1 $x >> iplist
> done
ping: unknown host cat
delos@linux:~/down> for x in 'cat ipz'
> do
> ping -c 1 $x >> iplist
> done
ping: unknown host cat
delos@linux:~/down>
iplist is created but it is empty. some of the ips in my list (home/delos/down/ipz) work for sure so that is not the problem.


edit: i seem to have been beaten with a stupid-stick today. for some reason i used '' instead of ``.


thank you for your help

You're using the wrong punctuation marks - you need backticks, not single quotes. Copy and paste this character: `

That is the tick you need to use.
