  • exit without saving history

    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`

  • Exit mc with 2 keystrokes

    For those who like to hit instead of typing "exit" to leave the shell and find it annoying that it doesn't work in Midnight Commander, just press to switch to the subshell and now you can leave with

  • Use exit codes that actually means something.

    Use meaningful exit codes change "source" to "cat" to view output instead of assigning Show Sample Output

  • Stores current working directory before exit and restores it on a new bash start

    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

  • MacOS: Make the terminal app always quit when

    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"

Download all music files off of a website using wget
This will download all files of the type specified after "-A" from a website. Here is a breakdown of the options: -r turns on recursion and downloads all links on page -l1 goes only one level of links into the page(this is really important when using -r) -H spans domains meaning it will download links to sites that don't have the same domain -nd means put all the downloads in the current directory instead of making all the directories in the path -A mp3 filters to only download links that are mp3s(this can be a comma separated list of different file formats to search for multiple types) -e robots=off just means to ignore the robots.txt file which stops programs like wget from crashing the site... sorry http://example/url lol..

Display _something_ when an X app fails
When you run an X program from a terminal you can see any errors. But when it's run from another X program (eg from a menu item, from your fluxbox 'keys' file etc) it might just die and you see nothing (except perhaps in .xsession-errors). Instead, launch it via this command and you'll see the termination status, stderr and stdout. eg: "xlaunch firefox" or "xlaunch 'echo stdout; echo stderr >&2; false'": 'echo stdout; echo stderr >&2; false' failed with error 1 STDERR: stderr STDOUT: stdout

Find usb device in realtime

Change every instance of OLD to NEW in file FILE
Very quick way to change a word in a file. I use it all the time to change variable names in my PHP scripts (sed -i 's/$oldvar/$newvar/g' index.php)

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Takes and displays screenshot of Android phone over adb.
Dependencies on phone: adb access, screencap command, base64 command. Dependencies on computer: adb, sed, base64, display (from imagemagick, but can substitute other image viewer which reads from stdin). This should work around adb stupidies (i.e. that it replaces \n with \r\n) with base64.

Extract rpm package name, version and release using some fancy sed regex
This command could seem pretty pointless especially when you can get the same result more easily using the rpm builtin queryformat, like: $ rpm -qa --qf "%{NAME} %{VERSION} %{RELEASE}.%{ARCH}\n" | sort | column -t but nonetheless I've learned that sometimes it can be quite interesting trying to explore alternative ways to accomplish the same task (as Perl folks like to say: There's more than one way to do it!)
