w3m is a commanline web browser, full of options, I used -dump_head for less unnecessary page download.

With awk, I can retrieve dynamic changes in webpages in this very econnomical fashion

Speaks whatever comes in via stdin (-v pt = portuguese, default = englisg)

..speech part of keyboard event talker. Made to accomplish a simple alarm central based on a cheap keyboard circuit. This way I have one zone per direct keypress. Depends on keypress.sh. It speaks out loud wich zone (key) has been pressed ( faulted ). Here is keypress.sh :

#!/bin/bash

# keypress.sh: Detect a user keypress ("hot keys").

echo

old_tty_settings=$(stty -g) # Save old settings (why?).

stty -icanon

Keypress=$(head -c1) # or $(dd bs=1 count=1 2> /dev/null)

# on non-GNU systems

aplay -q /home/mm/bash/beep-1.wav

echo

echo "Chamada quarto \""$Keypress"\"."

echo

stty "$old_tty_settings" # Restore old settings.

What do you do when nmap is not available and you want to see the hosts responding to an icmp echo request ? This one-liner will print all hosts responding with their ipv4 address.

just change the date following the -r flag, and/or the user name in the user== conditional statement, and substitute yms_web with the name of your module

fancy command line ncdu clone

Ever compress a file for the web by replacing all newline characters with nothing so it makes one nice big blob?

It is a great idea, however what about when you want to edit that file? ...Serious pain in the butt.

I ran into this today in that my only copy of a CSS file was "compressed" with no newlines.

I whipped this up and it converted back into nice human readable CSS :-)

It could be nicer, but it does the job.

The variable WIRELESSINTERFACE indicates your wireless interface

This will allow you to mount a CD-ROM on Solaris SPARC 9 or lower. This will not work on Solaris 10 due to void and the volume management daemons.

Really only valuable in a PHP-only project directory. This is using standard linux versions of the tools. On most older BSD variants of sed, use -E instead of -r. Or use: sed 's/\+[[:space:]]\{1,\}//' instead.

This appends a random number as a first filed of all lines in SOMEFILE then sorts by the first column and finally cuts of the random numbers.

Sometimes jittery data hides trends, performing a rolling average can give a clearer view.

exported files will get a .r23 extension (where 23 is the revision number)

change 24073 to your pid

Just find out the daemon with $ netstat -atulpe. Then type in his name and he gets the SIGTERM.

does the same, but shows network-prefix.

This is meant for the bash shell. Put this function in your .profile and you'll be able to use tab-completion for sshing any host which is in your known_hosts file. This assumes that your known_hosts file is located at ~/.ssh/known_hosts. The "complete" command should go on a separate line as such:

function autoCompleteHostname() {

local hosts=($(awk '{print $1}' ~/.ssh/known_hosts | cut -d, -f1));

local cur=${COMP_WORDS[COMP_CWORD]};

COMPREPLY=($(compgen -W '${hosts[@]}' -- $cur ))

}

complete -F autoCompleteHostname ssh

Change ~/tmp to the destination directory, such as your mounted media. Change -n20 to whatever number of files to copy. It should quit when media is full. I use this to put my most recently downloaded podcasts onto my phone.

automatically add and remove files in subversion so that you don't have to do it through the annoying svn commands anymore

And then to complete the task:

Go to target host;

Turn everything off:
