alias private_mode='unset HISTFILE && echo -e "\033[1m[\033[0m\033[4m*\033[0m\033[1m] \033[0m\033[4mprivate mode activated.\033[0m"'

private mode for (bash) shell

same as "unset HISTFILE" - but the advantage is that you can "tab-complete" it and when you do, you won't mistype it (which could lead to not unsetting the HISTFILE). put the alias in the ~/.bash_profile or ~/.bashrc file in your users home directory, respawn, enjoy! :)
Sample Output
[*] private mode activated.

  • Was playing with the shell. It struck to me, just by rearranging the parameters, i was able to remember what they did and in a cool way. Enter the 'hitlar' mode. bash-3.2$ ls -hitlar Shows all items with inodes, in list view, human readable size, sorted by modification time in reverse, bash-3.2$ ls -Fhitlar Shows the same with classification info. Add the hitlar mode alias to your .bashrc. bash-3.2$ echo "alias hitlar='ls -Fhitlar'" >> ~/.bashrc bash-3.2$ hitlar bash-3.2$ hitlar filename Show Sample Output

    ls -Fhitlar

  • This will create, in the current directory, a file called 'pk.pem' containing an unencrypted 2048-bit RSA private key and a file called 'cert.pem' containing a certificate signed by 'pk.pem'. The private key file will have mode 600. !!ATTENTION!! ==> this command will overwrite both files if present.


    1
    touch pk.pem && chmod 600 pk.pem && openssl genrsa -out pk.pem 2048 && openssl req -new -batch -key pk.pem | openssl x509 -req -days 365 -signkey pk.pem -out cert.pem

  • Dave Korn gave me this one. It works because ksh allows variable names ( w/o the $name syntax ) used by sh and bash. I wrote it to permit "single source" shell libraries; the current objective: every shell library may be sourced by either shell. see http://github.com/applemcg/backash Show Sample Output


    2
    isKsh () { one=1; [ one -eq 1 ] 2> /dev/null; }

  • Starts a new shell (in bash/sh, it starts bash/sh). 'man bash' explains: "If arguments remain after option processing, and neither the -c nor the -s option has been supplied, the first argument is assumed to be the name of a file containing shell commands. If bash is invoked in this fashion, $0 is set to the name of the file, and the positional parameters are set to the remaining arguments."

  • Next time you are using your shell, try typing ctrl-x ctrl-e # in emacs mode or <ESC> v # in vi mode The shell will take what you've written on the command line thus far and paste it into the editor specified by $EDITOR. Then you can edit at leisure using all the powerful macros and commands of vi, emacs, nano, or whatever. Show Sample Output

    <ESC> v or ctrl-x ctrl-e

  • If you spend all day editing in vi then switching your fingers to Emacs mode just for the command line can be difficult. Use set -o vi in your bash shell and enjoy the power of a real editor.

    set -o vi; ls -l jnuk<ESC>bCjunk
