On a GNU/Linux system, I can run this:
In my case, I'm just counting ssh sessions. You can change ":22 " to ":1521 " for your specific need. No need to filter, extract and sort if all you want is a count.
I've got a diff command running in a shell script that writes the ouput to a new file. In the new file there is a ">" at the beginning of each line. The output file is going to be used by another program and that character makes the file useless.
What I'm getting in the new file:

I wrote myself a small little shell script to clean up a file I have issues with. In particular, I am stripping down a fully qualified host/domain name to just the hostname itself. The script works, but from a performance standpoint, it's not very fast and I will be working with large data sets.

checkrestart - check which processes need to be restarted after an upgrade
SYNOPSIS
checkrestart [ -hvpa ] [ -b blacklist_file ] [ -i package_name ]
DESCRIPTION
The checkrestart program tries to determine if there are processes in the system that need to be restarted after a system upgrade. This is
necessary since an upgrade will usually bring new system libraries and running processes will be still using the old versions of the
libraries. In stable Debian GNU/Linux systems this is typically needed to eliminate a system exposure to a vulnerability which might have
been fixed by upgrading a library which that process makes use of.
Consequently, checkrestart is sometimes used as an audit tool to find outdated versions of libraries in use, particularly after security
upgrades. Administrators should not, however, rely on its output completely (see BUGS below).
This script needs to run as root in order to obtain the information it needs for analysis.
OPTIONS -h,--help
Show the program help and exit.
-v,--verbose
Generate detailed output. This output includes the list of all processes found using deleted files or descriptors as well as the
deleted files and descriptors found.
-p,--package
Only process deleted files that belong to a package, ignoring deleted files which do not have an associated package in the package
system.
-a,--all
Process all deleted files regardless of location. This makes the program analyse deleted files even if they would be discarded
because they are located in locations, such as /tmp , which are known to produce false positives. It will take preceded if used
simultaneously with the -p option.
-b file,--blacklist=file
Read a blacklist of regular expressions from file. Any files matching the patterns will be ignored.
-i name,--ignore=name
Ignore services that are associated to the package name provided in name.
EXIT STATUS
The program will exit with error (1) if a non-root user tries to run it. Otherwise, it will always exit with error status 0.
BUGS
This program might fail if the output of the lsof utility changes since it depends on it to detect which deleted files are used by pro-
cesses. It might also output some false positives depending on the processes' behaviour since it does not check yet if the (deleted) files
in use are really libraries.
If you find a false positive in checkrestart please provide the following information when submitting a bug report:
-- The output of checkrestart using the -v (verbose) option.
-- The output of running the following command as root:
lsof | egrep 'delete|DEL|path inode'
Checkrestart is also sensitive to the kernel version in use. And might fail to work with newer (or older) versions.
A rewrite to make it less dependent on lsof could improve this, however.
