This command takes an application name as an argument and then it will listen to the tcp traffic and capture packets matching the process Id of the application.
The output shows:
local address / local port / Remote Address / Remote port / State / Owning Process ID
It works as a method applicated to a variable, converts the string variable into an array
It is helpful to know the current limits placed on your account, and using this shortcut is a quick way to figuring out which values to change for optimization or security.

Copies the complete root-dir of a linux server to another one, where the new harddisks formated and mountet. Very useful to migrate a root-server to another one.
find . -type f -iname '*.flac' # searches from the current folder recursively for .flac audio files
| # the output (a .flac audio files with relative path from ./ ) is piped to
while read FILE; do FILENAME="${FILE%.*}"; flac -cd "$FILE" | lame -b 192 - "${FILENAME}.mp3"; done
# for each line on the list:
# FILE gets the file with .flac extension and relative path
# FILENAME gets FILE without the .flac extension
# run flac for that FILE with output piped to lame conversion to mp3 using 192Kb bitrate
Streams youtube video with v=ID directly into the mplayer.
If exists, it uses the HD-quality stream.
If you don't want to watch it in HD-quality, you can use the shorter form:
$ID=52DnUo6wJto; mplayer -fs $(echo "http://youtube.com/get_video.php?&video_id=$ID$(wget -qO - 'http://youtube.com/watch?v='$ID | perl -ne 'print $1."&asv=" if /^.*(&t=.*?)&.*$/')")
Normally, searching git log comments is case sensitive. The -i luckily applies to the --grep switch.

-n: dereference the existing link
-v: (optional) to be sure of what is being done
-f: force the deletion of the existing one
-s: creates a symlink
Be careful: the destination can also be a file or a directory and it will be overwritten.
