Miscellaneous bash tips
A few useful configuration bits:
# Don't put duplicate lines in the history export HISTCONTROL=ignoredups # When you use history expansion (the !something), allows to edit the # expanded line before executing it shopt -s histverify # Correct spelling mistakes when using 'cd' shopt -s cdspell # Do not attempt completion on an empty line shopt -s no_empty_cmd_completion
A few useful keystrokes:
- Alt + dot: insert the last argument of the previous command. Equivalent
to inserting the expansion of
!$at the cursor position.
- Alt + >: go to the end of the history. Sometimes it happens, when using
Ctrl + r, that I mistakenly land before the command that I was looking
for, and I need to hold arrow-down for a while to go back at the end. This
does the trick. Of course, Alt + < goes at the beginning. Also, Ctrl
*.jpgexept maybe a few of them? Ctrl + Alt + e does full expansion on the current line, and Alt + ^ does history expansion only. If the expansion is too big, use Ctrl+x then Ctrl+e, which loads the current command in an editor and runs when you exit the editor.
For more useful keystrokes, run
man bash, look for "Commands for Manipulating
the History" and read down from there.
