for loop command 3

[geoffinva3]

Ok I don't have a million years to learn unix scripting

I just need the syntax to use the for loop command

I have a file with a list of IP addresses in it
I want to excute the command ping on each address in the list. In addition it should output to a file where I see the ip address of each and the result of ping.


Can anyone bail a guy out

Thanks!!!

ok, that's fair - how many years DO you have?

here's something to start with - assuming one IP per line in the file:

#!/bin/ksh

fileIPs='/path/to/the/IPfile'

while read ip
  ping "${ip}"
done < "${fileIPs}"

in addition to vgersh99's post, do a "man ping" in order to delimitate the ping output. ping some_host will generate a endless list for only one host. you should use something like "ping -c 2 host" .. it means, ping twice to the host.

Cheers.

OK thanks for the help yesterday. I decided to use some of my time for better use. I went home last night and learned something if you can beiev it. and by god it worked it printed each line to standard out. Now I want to change it to read the line and than execute the ping command on each any ideas?

I tried Perl and wrote the following bit of code:


1: #!/usr/local/bin/perl

2:

3: if (open(MYFILE, "file1")) {

4: $line = <MYFILE>;

5: while ($line ne "") {

6: print ($line);

7: $line = <MYFILE>;

8: }
