Tips: Shortcuts on the current line

Try these useful bash shell shortcuts:

• Ctrl+A: move to the start of the current line
• Ctrl+E: move to the end of the line
• Alt+F: move to the end of the next word
• Alt+B: move to the start of the current or previous word

• Ctrl+T: swap the two last characters, e.g.: 

  sl<C-t>

   → 

  ls

• Alt+T: swap the last two words, e.g.: 

  foo bar<M-t>

   → 

  bar foo

• Ctrl+U: cut the text of the current command before the cursor.
• Ctrl+W: cut only the word before the cursor.
• Ctrl+K: cut the text of the current command after the cursor.
• Ctrl+Y: paste the previously cut text after the cursor. This is useful when you have typed a long command and realize that you forget to do something before, e.g.:

  1 2 3

  % ./my_long_command -v -u foobar -t -x<C-U> % ./do_something_before % <C-Y><enter> # paste and execute ./my_long_command…

• Alt+U: uppercase the next word, e.g.: 

  ls<C-a><M-u>

   → 

  LS

• Alt+L: lowercase the next word, e.g.: 

  LS<C-a><M-l>

   → 

  ls

• Alt+C: capitalize the next word, e.g.: 

  foo<C-a><M-c>

   → 

  Foo

• Ctrl+L: clear the screen, leaving the current line at the top.
• Ctrl+_: undo (incremental).
