After reviewing the suggested post I've come up with the following code:
The ip address ranges are correctly converted to CIDR and printed to the console. Instead of printing to the console how do I send the information to a file instead? I don't need anything printed to the console. Also I was interested in mawk since might be faster than gawk. mawk doesn't have the lshift rshift etc. Can someone make the code more portable so I can use try mawk.
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 :-(

Hi,
Please anyone help to achive this using perl or unix scripting .
This is date in my table 20090224,based on the date need to check the files,If file exist for that date then increment by 1 for that date and check till max date 'i.e.20090301 and push those files .

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
chr1_34500_34550 ... (7 Replies)
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

Weary of seeing our load average go up to 50+, I just did a major block on these networks (stats over a less than 20 min interval):

SYSTEMD.SLICE(5) systemd.slice SYSTEMD.SLICE(5)NAME
systemd.slice - Slice unit configuration
SYNOPSIS
slice.slice
DESCRIPTION
A unit configuration file whose name ends in ".slice" encodes information about a slice unit. A slice unit is a concept for hierarchically
managing resources of a group of processes. This management is performed by creating a node in the Linux Control Group (cgroup) tree. Units
that manage processes (primarily scope and service units) may be assigned to a specific slice. For each slice, certain resource limits may
be set that apply to all processes of all units contained in that slice. Slices are organized hierarchically in a tree. The name of the
slice encodes the location in the tree. The name consists of a dash-separated series of names, which describes the path to the slice from
the root slice. The root slice is named -.slice. Example: foo-bar.slice is a slice that is located within foo.slice, which in turn is
located in the root slice -.slice.
Note that slice units cannot be templated, nor is possible to add multiple names to a slice unit by creating additional symlinks to its
unit file.
By default, service and scope units are placed in system.slice, virtual machines and containers registered with systemd-machined(1) are
found in machine.slice, and user sessions handled by systemd-logind(1) in user.slice. See systemd.special(5) for more information.
See systemd.unit(5) for the common options of all unit configuration files. The common configuration items are configured in the generic
[Unit] and [Install] sections. The slice specific configuration options are configured in the [Slice] section. Currently, only generic
resource control settings as described in systemd.resource-control(5) are allowed.
See the New Control Group Interfaces[1] for an introduction on how to make use of slice units from programs.
IMPLICIT DEPENDENCIES
The following dependencies are implicitly added:
o Slice units automatically gain dependencies of type After= and Requires= on their immediate parent slice unit.
DEFAULT DEPENDENCIES
The following dependencies are added unless DefaultDependencies=no is set:
o Slice units will automatically have dependencies of type Conflicts= and Before= on shutdown.target. These ensure that slice units are
removed prior to system shutdown. Only slice units involved with late system shutdown should disable DefaultDependencies= option.
