The following command e-mails myself a file:

sudo mail -a FILE_ADDRESS -s "Subject of E-mail" myemail@gmail.com

Question: How do I turn this command into a one-liner, so that I could just type something like

email_myself FILE_ADDRESS

A related question is as follows: is there a way for me to make it so that all I have to do is just right-click on a file, and then I can execute this command on it? Or do something like e-mail myself the contents of my clipboard (such that if it's a file, it e-mails me the file, or if it's text, it e-mails me the text)? (Note I'm using Ubuntu). I think this would be an incredibly useful script :)

Make a function:

email_myself() { sudo mail -a "$1" -s "Subject of E-mail" myemail@gmail.com; }

If you want your function to hang around permanently, and assuming that bash is your shell, add the definition as a line to your ~/.bashrc.

For those who prefer shell scripts to functions, create a file named email_myself, make it executable (chmod +x email_myself), and save it somewhere on your PATH:

#!/bin/sh
sudo mail -a "$1" -s "Subject of E-mail" myemail@gmail.com

Other mail programs

On my system, the mail command does not work like that. For one, sudo is unnecessary. For another, -a does not attach a file; it is used to specify additional headers. Thus, I would use:

email_myself() { mail -s "Subject of E-mail" myemail@gmail.com <"$1"; }

  • I add a bin/ directory to my home directory and place shell scripts and other tools there (adding ~/bin/ to path). But a shell function works... – ChuckCottrill Oct 9 '14 at 21:19

    @ChuckCottrill My ~/bin directory has over 500 scripts in it. I have found, though, that there are many who prefer functions. – John1024 Oct 9 '14 at 21:29
