Since you might find yourself inside the Terminal (command prompt) more often on Linux, do try to document which commands you find yourself using, and what they do. You'll probably paste a few in from Google/stack overflow answers. Some of the common commands:
Since you might find yourself inside the Terminal (command prompt) more often on Linux, do try to document which commands you find yourself using, and what they do. You'll probably paste a few in from Google/stack overflow answers. Some of the common commands:
*`ls` -> show contents of directory (ls -alh, show it more readably)
*`ls` -> show contents of directory (`ls -alh`, show it more readably)
*`cd` -> change directory (learn cd /, cd ~, cd .. for moving around using relative, rather than absolute paths to things)
*`cd` -> change directory (learn `cd /`, `cd ~`, `cd ..` for moving around using relative, rather than absolute paths to things)
*`find` -> print paths to files/folders matching some criteria

*`grep` -> use regular expressions to find lines in files that match some search string

The first line of the script, called a shebang, tells your system which language the program is written in (bash, the default language of your terminal). You'd save this as `update.sh`, then you'd tell Linux you want to be able to execute the file with:
The first line of the script, called a shebang, tells your system which language the program is written in (bash, the default language of your terminal). You'd save this as `update.sh`, then you'd tell Linux you want to be able to execute the file with:
```chmod +x update.sh```
```bash
chmod +x update.sh
```
You can then do ./update.sh to run your script. If it prints the Finished line, it worked, and you're a programmer now. You can even move the file to /usr/bin, and then you can run it from any directory at any time just by typing update.sh! But, since you're a programmer now, you actually make a repository containing all your cool scripts, and you keep this and other scripts that you write under version control in that repository. That way you can improve it over time, while keeping its history, blah blah.

One other thing you'll want to do quite quickly, install Atom and/or Sublime Text, and then set those in terminal as your default editor, so that files are opened for editing using those apps, rather than in the terminal's default (terminal-based) editor (nano or vim, both of which require some practice).

These instructions tell you something really valuable, that you can add lines to this `~/.bashrc file`. This file contains your terminal preferences and shortcuts and so on. For example, I add:
These instructions tell you something really valuable, that you can add lines to this `~/.bashrc file`. This file contains your terminal preferences and shortcuts and so on. For example, I add:
```alias la="ls -alh"```
And then do `source ~/.bashrc` to reload the settings. This gives me a new command, `la`, which is just the same as doing `ls -alh` but shorter. So yeah, back to the *point*, you use this same preferences file to store your preferred text editor, so that when you do things in terminal requiring a text editor, it'll open the file with Atom, much easier than learning `vim` right now.

\ No newline at end of file
