Forgive my ignorance. I get wrong results when running the script with a file containing the following IP address ranges. Note that the IP address ranges are separated by a space hyphen space.
Example
When I changed the field separator to include space hyphen space FS="-| - |:" it correctly converts the IP ranges.
This field separator FS="[- :]" will not properly convert my example IP ranges in this post. Granted, the script you posted doesn't parse the downloaded file to include a space before and after the hyphens that separate IP ranges. I think the script is more flexible now since it will also properly convert the example I provided.
Can you test and confirm that the field separators that I posted and the one you posted are indeed the same? I get different results. Please test against the example that I have just posted.
Dear Srs :-)
I'm looking for a shell script, that given a network in CIDR format it lists all IPs, for example:
Preferredly a shell script, but a Perl, Python, C, etc.. is also welcome :-)
I have been looking in sipcalc, ipcalc, etc.. options but this feature is not implemented :-(

Hello everybody,
I'm coding a network program and i need it to "understand" ip ranges, but i don't know how to make to parse an IP CIDR range, let's say "172.16.10.0/24" to work with the specified IP range.
I've found a program which does it, but i don't understand the code. Here is the... (3 Replies)
I have a list of about 200,000 lines in a text file that look like this:
1 1 120
1 80 200
1 150 270
5 50 170
5 100 220
5 300 420
The first column is an identifier, the next 2 columns are a range (always 120 value range)
I'm trying fill in the values of those ranges, and remove... (4 Replies)
Hi,
I have two files
file1 chr1_22450_22500
chr2_12300_12350
chr1_34500_34550
file2 11000_13000
15000_19000
33000_44000
If the file 1 ranges fall between file2 ranges then assign the value of file2 in column 2 to file1
output:
chr2_12300_12350 11000_13000

Looking for a simple way to convert ranges to a numerical sequence that would assign the original value of the range to the individual numbers that are on the range.
Thank you

Hi all, I would appreciate if someone could share how to convert CIDR notation to netmask and vice versa.
The value below is just an example. it could be different numbers/ip addresses.
Initial Output, let say file1.txt
Final Output, let say file2.txt (3 Replies)
Hi,
Recently I had to convert a 280K lines of ip ranges to the CIDR notation and generate a file to be used by ipset (netfilter) for ip filtering.
Input file:
000.000.000.000 - 000.255.255.255 , 000 , invalid ip
001.000.064.000 - 001.000.127.255 , 000 , XXXXX

clfsplit
clfsplit(1) logtools clfsplit(1)NAME
clfsplit - split Common-Log Format web logs based on IP address
SYNOPSIS
clfsplit [--help] [-i input] -d defaultfile -f file -s spec [-f file -s spec]
DESCRIPTION
The clfsplit will split up large CLF format web logs based on IP address. This is for creating separate log analysis passes for internal
and external users of web pages.
OVERVIEW
The defaultfile parameter specifies where data goes if it doesn't match any of the IP ranges. This could be /dev/null depending on your
aims.
The -i input parameter gives the file to take input from (default standard input).
The -f file parameter must be given before the list of IP addresses.
The spec parameter is the IP addresses that go to the file in question. It is of the form start[-end][:start[-end]] where start and end
specify the start and ends of ranges of IPs. Also the CIDR notation can be used or a single IP address. If there is a large number of IP
ranges then a file name can be given which contains a set of IP ranges, one range per line.
EXIT STATUS
0 No errors
1 Bad parameters
2 Can't open input
3 Can't open/write to output file
4 Can't open and read from spec file
