Monitoring TCP connections number

Monitoring TCP connections number showing each state. It uses ss instead of netstat because it's much faster with high trafic.

You can fgrep specific ports by piping right before awk:

watch "ss -nat | fgrep :80 | awk '"'{print $1}'"' | sort | uniq -c"

export DOIT_HOST=$(who -m | sed 's/.*(\(.*\)).*/\1/')

Note that SSH_CLIENT variable can be lost if you use su or sudo (if set to reset vars)

Simultaneously running different Firefox profiles

If you need to create a profile and are already running Firefox, you don't need to close it to do it. Also, if you don't know the exact name of the profile, this would allow you to pick from a list.

Find out the starting directory of a script

I think this is the cleanest way of getting the current working directory of a script. It also works on osx, Linux, and probably bsd as well..

find and kill a pid for APP

Probably posted previously, I use this all the time to find and kill a process for "APP". Simply replace "APP" with the name of the process you're looking to kill.

change to the previous working directory

This is like `cd -` but doesn't echo the new directory name, which is preferable (to me) for an alias, e.g.

alias cdo="cd $OLDPWD"

kill all processes with name or argument

Be careful when issuing this command, it may kill unwanted processes!

To only search on the process name don't use the argument -f, pkill foo

Sort all the ".dat" files in current directory by column 3 (change it accordingly), and replace the sorted one with original.

We normally get tasks in which one has to sort a data file according to some column. For a single file say foo, we would use

sort -k 3 foo >tmp && tmp foo

The for loop is useful when we have to do it on a number of files.
