Terminal Shortcuts

Up Arrow or ctrl+p Scrolls through the commands you’ve entered previously.
Down Arrow or ctrl+n Takes you back to a more recent command.
Enter When you have the command you want.
tab A very useful feature. It autocompletes any commands or filenames, if there’s only one option, or else gives you a list of options.
ctrl+r Searches for commands you’ve already typed. When you have entered a very long, complex command and need to repeat it, using this key combination and then typing a portion of the command will search through your command history. When you find it, simply press Enter.
History The history command shows a very long list of commands that you have typed. Each command is displayed next to a number. You can type !x to execute a previously typed command from the list (replace the X with a number). If you history output is too long, then use history | less for a scrollable list.

Uncompress

tar -zxfv filename.gz
