Hi,
I'm fairly new to shell programming so this is hopefully just a simple
syntax error.

What I'm trying to do is to get an ip address from "file1.txt", ping it once
and put this in "file2.txt".  Here's my code:

address = awk $1 file1.txt;
ping "$address"-c 1 >> file2.txt;
echo
" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~">>file2.txt;;

can anybody tell me where I'm going wrong?

file1.txt is set out as below:
192.168.0.1
192.168.0.2
13.65.98.2
255.255.25.255
156.285.24.2
1.2.3.4

etc... jus a list of IP addresses, each on a new line in dotted decimal
form.

and hopefully file2 will look like this:

PING 192.168.0.1 (192.168.0.1) from 192.168.0.2 : 56(84) bytes of data.
64 bytes from 192.168.0.1: icmp_seq=1 ttl=128 time=0.214 ms

--- 192.168.0.1 ping statistics ---
1 packets transmitted, 1 received, 0% loss, time 0ms
rtt min/avg/max/mdev = 0.214/0.214/0.214/0.000 ms
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

and so on...

any help would be much appreciated.

thanks for any replies

You'll need a loop to do that.  Something like this:

while read address; do
ping -c1 $address
echo "~~~~~~~~~~~~~~~~~~"
done < file1.txt > file2.txt

Hints:
for i in `cat file1.txt`; do
..
done > file2.txt
or
while read i; do
..
done < file1.txt > file2.txt

sorted, thanks very much.

I ended up with:

for i in `cat file1.txt $1`; do
ping $i -c 1;
done >> file2.txt;;
