[GUFSC] dicas Bash

[Ricardo Grützmacher]

Apesar de eu usar o zsh que é mais inteligente que o bash lá vão algumas

Bash Key Combinations

Alt+B   // Go back one word
Alt+F   // Go forth one word
Ctrl+K  // Delete everything from the cursor to the end of the line
Ctrl+U  // Delete everything from the cursor to the beginning of the line
Ctrl+Y  // Paste deleted characters at the current position
Ctrl+H  // Delete one character
Ctrl+L  // Clean screen
Ctrl+P  // Go to the previous history entry
Ctrl+N  // Go to the next history entry

Also you can use !word to re-execute the last command beginning with "word".

Using !word

$ gcc -o test test.c
$ !gcc
gcc -o test test.c
$

// pushd adds a directory
~:$ pushd /usr/portage
// dirs lists all directories on the stack
~:$ dirs
/usr/portage ~

~:$ popd
/usr/portage:$
