Sort lines on clipboard
Does the same thing in environments where you have "xclip" instead of "pbpaste"/"pbpate" and "pbcopy".

beep when a server goes offline
pings a server once per second, and beeps when the server is unreachable. Basically the opposite of: $ ping -a server-or-ip.com which would beep when a server IS reachable. You could also substitute beep with any command, which makes this a powerful alternative to ping -a: $ while true; do [ "$(ping -c1W1w1 server-or-ip.com 2>/dev/null | awk '/received/ {print $4}')" = 1 ] && date || echo 'server is down!'; sleep 1; done which would output the date and time every sec until the ping failed, in which case it would echo. Notes: Requires beep package. May need to run as root (beep uses the system speaker) Tested on Ubuntu which doesn't have beep out of the box... $ sudo apt-get install beep

netstat with group by (ip adress)
Same as the rest, but handle IPv6 short IPs. Also, sort in the order that you're probably looking for.

Convert encoding from cp1252 (MS Windows) to UTF-8 on source code files

Read choice from user instantaneously
Usage exaple cmd $echo 'Sure to continue ??'; read -n1 choi; if [ "$choi" = 'y' ] || [ "$choi" = 'Y' ]; then echo -e '\nExecuting..'; else echo 'Aborted'; fi

check open ports without netstat or lsof

Commands on svn stat

Aptitude pattern match
Could be dangerous, if you have many packages all beginning with 'foo' or 'bar'. This will easily remove them all from your system.

Benchmark SQL Query
Benchmark a SQL query against MySQL Server. The example runs the query 10 times, and you get the average runtime in the output. To ensure that the query does not get cached, use `RESET QUERY CACHE;` on top in the query file.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
