  • Testing ftp server status

    I must monitorize a couple of ftp servers every morning WITHOUT a port-scanner Instead of ftp'ing on 100 ftp servers manually to test their status I use this loop. It might be adaptable to other services, however it may require a 'logout' string instead of 'quit'. The file ftps.txt contains the full list of ftp servers to monitorize.


    1
    for host in $(cat ftps.txt) ; do if echo -en "o $host 21\nquit\n" |telnet 2>/dev/null |grep -v 'Connected to' >/dev/null; then echo -en "FTP $host KO\n"; fi done

  • Toggle the Touchpad on or off

    This command toggles the touchpad on and off, when it's on, the right side scroll strip (annoying) and the tap-clicking are disabled, you can change this by changing occurances of 2 in the command to 0. this whole command can then be given a keyboard shortcut so that the touchpad is disableable without using a special fn key (which linux doesn't recognize on some computers) or a seperate button.


    -3
    if [ $(synclient -l | grep TouchpadOff | awk '{print $3}') = "2" ]; then synclient TouchpadOff=1; elif [ $(synclient -l | grep TouchpadOff | awk '{print $3}') == "1" ]; then synclient TouchpadOff=2; else synclient TouchpadOff=2; fi

  • Fast tape rewind

    Traditionally we rewind a tape using this syntaxis: mt -f /dev/rmt/0cbn rewind Redirecting the dispositive to nothing as shown above is faster. Less typing is always better.

  • Extract all 7zip files in current directory taking filename spaces into account

    Use find's built-in ability to call programs. Alternatively, find -maxdepth 1 -type f -name "*.7z" -print0 | xargx -0 -n 1 7zr e would work, too.


    -1
    find -maxdepth 1 -type f -name "*.7z" -exec 7zr e '{}' ';'

  • Set X keymap to dvorak and fix the Ctrl key.

    What to type to fix the keyboard when it's all qwerty and/or the modifier key to the left of the 'a' is doing something unexpected. In addition, I've also been known to use the altwin:meta_win and compose:ralt flags.

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.

Create a new file

Uniquely (sort of) color text so you can see changes
Colorify colors input by converting the text to a number and then performing modulo 7 on it. This resulting number is used as the color escape code. This can be used to color the results of commands with complex outputs (like "482279054165371") so if any of the digits change, there's a good chance the color will change too. I say good chance because there's only 7 unique colors here, so assuming you were watching random numbers, there would be a 6/7 chance that the color would change when the number changed. This should really only be used to help quickly identify when things change, but should not be the only thing relied upon to positively assert that an output has not changed.

Change the extension of a filename by using rename to convert
This will change all files ending in .JPG to .jpg and will work with any file extension

Customer Friendly free
makes more sense to customers XD

Convert decimal numbers to binary
Convert some decimal numbers to binary numbers. You could also build a general base-converter: $ function convBase { echo "ibase=$1; obase=$2; $3" | bc; } then you could write $ function decToBun { convBase 10 2 $1; }

Check a server is up. If it isn't mail me.
Alternative to the ping check if your firewall blocks ping. Uses curl to get the landing page silently, or fail with an error code. You can probably do this with wget as well.

Countdown Clock
The biggest advantage over atoponce's nifty original is not killing the scrollback. Written assuming bash, but shouldn't be terribly difficult to port to other shells. S should be multiple spaces, but I can't get commandlinefu to save/show them properly, any help?

List all installed kernels on Ubuntu except current one
Lists all installed kernels minus the current one. This is useful to uninstall older kernels that take too much space on /boot partition.

Alert visually until any key is pressed
I learned a few things reading this command. But I did run into a few issues: 1. On systems that don't use GNU echo (e.g. macOS 10.14.5 Mojave), the e option may not be supported. In this case ANSI escape codes will echoed as text and the terminal will not flash, like this: \e[?5h\e[38;5;1m A L E R T Thu Jun 20 16:31:29 PDT 2019 2. Since the read command strips\ignores leading backslashes, if a user types the backslash character once in the loop, it will not break. Typing backslash twice in a loop will break as expected. 3. The foreground color is set to red (\e[38;5;1m) on every loop. This could be set once before we call while, and then reset once when the loop breaks. 4. Instead of resetting the foreground color when it breaks, the video mode is set back to normal (\e[?5l). This has the effect of leaving the terminal text red until it is manually reset. The alternative I'm proposing here addresses these issues. I tested it on macOS and Arch Linux.
