Commands tagged exit (7)

  • this exits bash without saving the history. unlike explicitly disabling the history in some way, this works anywhere, and it works if you decide *after* issuing the command you don't want logged, that you don't want it logged ... $$ ( or ${$} ) is the pid of the current bash instance this also works perfectly in shells that don't have $$ if you do something like kill -9 `readlink /proc/self`

  • this command will add the following two lines into the ~/.bash_aliases: alias exit='pwd > ~/.lastdir;exit' [ -n "$(cat .lastdir 2>/dev/null)" ] && cd "$(cat .lastdir)" or redirect it to the ~/.bashrc if you like Donno, I find it usefull. You may also define an alias for 'cd ~' like - alias cdh='cd ~'


    -1
    echo -e 'alias exit='\''pwd > ~/.lastdir;exit'\''\n[ -n "$(cat .lastdir 2>/dev/null)" ] && cd "$(cat .lastdir)"' >> ~/.bash_aliases

  • When you use the "exit" command in a Linux terminal window, it not only closes the terminal window itself but also the terminal emulator app, such as GNOME Terminal or Konsole, that it belongs to. If you use the "exit" command on macOS, however, Terminal.app still shows a dot below its Dock icon and is still running in the background. This alias, when entered into ~/.zshrc, overrides this behavior.

    alias exit="killall Terminal"

Check These Out

Set laptop display brightness
Run as root. Path may vary depending on laptop model and video card (this was tested on an Acer laptop with ATI HD3200 video). $ cat /proc/acpi/video/VGA/LCD/brightness to discover the possible values for your display.

Check a server is up. If it isn't mail me.
For some reason the 2&>1 does not work for me, but the shorter stdout/stderr redirection >& works perfectly (Ubuntu 10.04).

Change string in many files at once and more.
Find all files that contain string XXX in them, change the string from XXX to YYY, make a backup copy of the file and save a list of files changed in /tmp/fileschanged.

Remove color codes (special characters) with sed
Removes ANSI color and end of line codes to the [{attr1};...;{attrn}m format.

Perl Command Line Interpreter
My Programming Languages professor assigned my class a homework assignment where we had to write a Perl interpreter using Perl. I really like Python's interactive command line interpreter which inspired this Perl script.

Play online music videos in terminal
pvl 'link1' 'link2' 'link3' Play Youtube, Vimeo, etc links without visual elements. Great for music videos when you just want the audio. You can control mplayer with this! Hit Ctrl-C twice to exit (if you're playing multiple files)

Check SSH public and private keys matching
Tested in bash4

Prints per-line contribution per author for a GIT repository
Uses line-porcelain in git blame, which makes it easier to parse the output.

True random passwords using your microphone noise as seed
Generate a truly random password using noise from your microphone to seed the RNG. This will spit out 12 password with 12 characters each, but you can save this into a bash script and replace 'pwgen -ys 12 12' with 'pwgen $@' so you can pass any paramters to pwgen as you would normally do.

list all file extensions in a directory
If your grep doesn't have an -o option, you can use sed instead.
