how to print off results

print from an ip_list file containing 300 ip's

the directory of the results is /var/tmp/1.1.1.1

the 1.1.1.1 will change according to the /tmp/ip_list file i.e

1.1.1.1
2.2.2.2
3.3.3.3

I need the results from /var/tmp/1.1.1.1 once done the script goes to the next ip address in /tmp/ip_list line by line

here's my attempt:
Code:
while read ip
do
  cat /var/tmp/1.1.1.1 / $ip
done < ip_list

If it's the 1.1.1.1 that's being replaced, don't put 1.1.1.1 in there.

Also, don't put spaces, that will seperate it into different filenames as far as the shell's concerned.
Code:
while read ip
do
  cat /var/tmp/$ip
done < ip_list

it seems to be printing stuff all over the place?

another requirement say if in /var/tmp/ there is only one particular line im interested in i.e the second to last line and i want this printed off then move onto the next ip address in /tmp/ip_list

how about:

Code:
while read ip
do
  printf "/var/tmp/%s: " $ip
  tail -2 /var/tmp/ip_list | head -1
done < /tmp/ip_list

forgot to mention that the file name is test.log

/var/tmp/1.1.1.1/test.log

/var/tmp/1.1.1.1:/test.log tail: cannot open input

ok works thanks for the pointers.

one thing I don't understand is $ip variable is used after printf statement then in tail statement after /var/tmp/$ip don't understand this bit
