Clean a wordlist for use with password cracking tools and rules

Using large wordlists is cumbersome. Using password cracking programs with rules such as Hashcat or John the ripper is much more effective. In order to do this many times we need to "clean" a wordlist removing all numbers, special characters, spaces, whitespace and other garbage. This command will covert a entire wordlist to all lowercase with no garbage.

Fix Chromium browser not starting

If AppArmor is installed with all profiles enforced, Chromium may refuse to start, printing a "failed to launch zygote process" error on stderr. This command switches the Chromium profile from enforce to complain mode, effectively un-sandboxing the browser, but depending on the system setup it may be a smaller deal than a nonfunctional application.

search manpages on the internets

manview searches man pages on the internets in case the man command doesn't work for some reason or if you think the man pages in Cornell's flavor of Solaris might differ from yours. It dumps the manpage info from lynx to less, so it ends up looking remarkably like a real manpage. Put it in your .bash_profile or .bashrc, and then you can use it like a regular command: typing "manview ssh" will give you the manpage for ssh.

The above command will: - open a Remote Desktop connection to [servername / IP Address], - authenticate using [username] and [password], - configure resolution to best fit your desktop (I have a 1366x768px resolution so I left space for 2 panels of 22px each), - sets the color depth for the connection to 16 bpp, - hides the window manager decorations, - enables compression of the RDP data stream, - enables persistent bitmap caching.

How to Kill Process that is Running on Certain Port in Windows?

I cannot run Tomcat from Eclipse. It says that there?s other process that is running on port 8080, but I don?t know what is the process, and how to stop it from the Services manger in Windows. So here?s how you can kill and find out what is that process: To find out what PID 8080 was (hopefully not a trojan) I typed tasklist /FI ?PID eq 8080″ taskkill /F /PID 2600

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.

Bypass 1000 Entry limit of Active Directory with ldapsearch

That command bypass the entry limit specifing page results size, when the search arrive to the limit ldapsearch magically reiterate it from the last entry.

git remove files which have been deleted

I've used technicalpickles command a lot, but this one handles whitespaces in filenames. I'm sure you want to create an alias for it :)

Alias TAIL for automatic smart output

Run the alias command, then issue $ps aux | tail and resize your terminal window (putty/console/hyperterm/xterm/etc) then issue the same command and you'll understand. $ ${LINES:-`tput lines 2>/dev/null||echo -n 12`} Insructs the shell that if LINES is not set or null to use the output from `tput lines` ( ncurses based terminal access ) to get the number of lines in your terminal. But furthermore, in case that doesn't work either, it will default to using the default of 80. The default for TAIL is to output the last 10 lines, this alias changes the default to output the last x lines instead, where x is the number of lines currently displayed on your terminal - 7. The -7 is there so that the top line displayed is the command you ran that used TAIL, ie the prompt. Depending on whether your PS1 and/or PROMPT_COMMAND output more than 1 line (mine is 3) you will want to increase from -2. So with my prompt being the following, I need -7, or - 5 if I only want to display the commandline at the top. ( http://www.askapache.com/linux/bash-power-prompt.html ) 275MB/748MB [7995:7993 - 0:186] 06:26:49 Thu Apr 08 [askapache@n1-backbone5:/dev/pts/0 +1] ~ $ In most shells the LINES variable is created automatically at login and updated when the terminal is resized (28 linux, 23/20 others for SIGWINCH) to contain the number of vertical lines that can fit in your terminal window. Because the alias doesn't hard-code the current LINES but relys on the $LINES variable, this is a dynamic alias that will always work on a tty device.

mplayer -af scaletempo

Pitch-correct play speed with mplayer. You can also use [] and {} keys to change play speed on-the-fly.

Mount a partition from within a complete disk dump

Suppose you made a backup of your hard disk with dd: dd if=/dev/sda of=/mnt/disk/backup.img This command enables you to mount a partition from inside this image, so you can access your files directly. Substitute PARTITION=1 with the number of the partition you want to mount (returned from sfdisk -d yourfile.img).

I have used single packet, and in a silent mode with no display of ping stats. This is with color and UI improvement to the http://www.commandlinefu.com/commands/view/10220/check-if-a-machine-is-online. It is as per the enhancements suggested.

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
