happened to find this not bad software to keep my files and folders safe! Even the free trial version has the fantastic functions to protect any private files from being seen by anyone except me. With it I can encrypt, hide or lock anything I want, amazin

I noticed some spammer posted an advertisement here for "not bad" encryption. Unfortunately, their software only runs under Microsoft Windows and fails to work from the commandline. My shell script improves upon those two aspects, with no loss in security, using the exact same "military-grade" encryption technology, which has the ultra-cool codename "ROT-13". For extra security, I recommend running ROT-13 twice. Show Sample Output

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Clear ARP table in linux.

Clears the "arp" table, without entering manually addresses (tested in Ubuntu).

Show a curses based menu selector

Not so much handy by itself, but very nice in shell scripts. This makes you a handy ncurses based checklist. Much like terminal installers, just use the arrow keys and hit 'Space' to adjust the selections. Returns all selected tags as strings, with no newline at the end. So, your output will be something like: "one" "two" "three" "four" "etc" For those who prefer bash expansion over gratuitious typing: $ whiptail --checklist "Simple checkbox menu" 12 35 3 $(echo {one,two,three,four}" '' 0"} ) Things to note: The height must includes the outer border and padding: add 7 to however many items you want to show up at the same time. If the status is 1, it will be selected by default. anything else, will be deselected.

Get a funny one-liner from www.onelinerz.net

Put this command in .bashrc and every time you open a new terminal a random quote will be downloaded and printed from onelinerz.net. By altering the URL in the w3m statement you can change the output: 1 to 10 lines - http://www.onelinerz.net/random-one-liners/(number)/ 20 newest lines - http://www.onelinerz.net/latest-one-liners/ Top 10 lines - http://www.onelinerz.net/top-100-funny-one-liners/ Top 10 lines are updated daily.

Graphical tree of sub-directories

Prints a graphical directory tree from your current directory

Disconnect a wireless client on an atheros-based access point

This command will disconnect the user whose mac was specified from the current list of clients from the wireless network when the network card is working in access point mode. Works on atheros-based access points which use the madwifi driver (not sure, but don't think it will work on access points which are not atheros-based, as it uses the atheros's iwpriv extensions). It will not prevent the user from reconnecting to the network, but may force the user to roam to another AP, with stronger signal.

Display a block of text: multi-line grep with perl

-n reads input, line by line, in a loop sending to $_ Equivalent to while () { mycode } -e execute the following quoted string (i.e. do the following on the same line as the perl command) the elipses .. operator behaves like a range, remembering the state from line to line.

Apache memory usage

Install pip with Proxy

Installs pip packages defining a proxy

List processes sorted by CPU usage

Get Unique Hostnames from Apache Config Files

Get a list of all the unique hostnames from the apache configuration files. Handy to see what sites are running on a server. A slightly shorter version.
