Hi,
I have a file containing IP addresses & ranges, their negations, and
comments. E.g.,
1.1.1.1 # comment A
2.2.2.2/29 # comment B
!3.3.3.3 # comment C
!4.4.4.4/28 # comment D
I need to extract those IPs & ranges, rearrange them into a
comma-separated list, e.g.,
1.1.1.1,2.2.2/29,!3.3.3.3,!4.4.4.4/28
I've read that Perl (which I don't know yet at all) is "best" for Text
processing like this.
The thing is that I need to do this from within a Bash script, and
assign the comma-separated list to a variable in that Bash script.
Can I even use Perl like this, from inside a Bash script?
What would be the right way to go about this?
Thanks.
