From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

source ~/.bash_history
Can a linux noob get an explanation of this?
source
is a bash shell built-in command that executes the content of the file passed as argument, in the current shell.~/.bash_history
contains all the commands you ever executed in bash (the default shell in most Linux systems)To add on to this explanation, you generally use
source ~/.bashrc
to reload your shell whenever you want to make changes to your user config. Tab completion weakens the barrier to destruction significantly (esp. in my case)Until you use a system that doesn't have a ~/.bashrc , and now your tab completion helpfully expands "~/.ba[TAB]" to "~/.bash_history" .
That's why I like fish, which shows matching commands you executed, so that you can easily redo them.
Ooh can I get an equivalent for zsh? :D
