Hi, welcome to this talk about Unix shortcuts! I discovered recently that two skilled devs I admire didn't know these little life-savers. They quickly go into muscle memory: productivity and RSI will thank you! --- class: center, middle # Unix shortcuts `All CLI: term, irb, sql…` .b[[@abelar_s](https://twitter.com/abelar_s) - [@ParisRB](https://twitter.com/parisrb) - [@RailsGirlsParis](https://twitter.com/railsgirlsparis)] [maitre-du-monde.fr](maitre-du-monde.fr) .contrib[[Contribute to this talk on GitHub!](https://github.com/abelards/abelards.github.com/edit/master/talks/unix_shortcuts.html)] ??? They're great because they work almost everywhere! In OS and my web IDE, I use a third of these daily. On a terminal-heavy day, two thirds. --- class: center # Alphabet - `ABCDEFGHIJKLMNOPQRSTUVWXYZ` - .best[`CZRAEDLKWY` my top 10] ??? So I propose we practice our alphabet: 26 simple letters for 26 simple shortcuts. I used these 10 daily, will probably now juse a few more. --- # Alphabet - `SQ` - `CZ` - `RGPN` - `AEBF` - `DLT` - `KUWH Y` - `IJMV` - `XO` ??? Of course I need a more convenient order, right? --- # Surprise! - `^S` XOFF - stops output on screen - `^Q` XON - turns back on ??? I mention these first because they can block your terminal. This is how some people think their computer stalled and lose a sessions' worth of work. --- # Processes - .best[`^C` kill process] - .best[`^Z` background] - `fg` foreground (+number) ??? One of the first things you need to know: kill/cancel if something goes wrong, and pause/reopen your work. --- # Search - .best[`^R` history] - `^G` cancel - `^P` prev history line - `^N` next history line ??? You liked what you did before? Want to do it again? Typed something you want to improve? Messed up something and want to clean that up? --- # Moving - .best[`^A` beginning of line] - .best[`^E` end of line] - `^B` backwards one char - `^F` forwards one char ??? These also work on Unix and MacOSX text fields. They are approved by the Church of Emacs. --- # Inputs - .best[`^D` EOF - end of input: stops or quits] - .best[`^L` clear screen] - `^T` invert characters ??? ^D is nice when you want to quit and forgot if it's `exit`, `quit` or whatever. --- # Deleting - .best[`^K` kill after cursor] - `^U` kill before cursor - `^W` kill word before cursor - `^H` kill character before cursor ??? Church of Emacs approved, except ^U --- # Deleting / Yanking - .best[.remark-code.remark-inline-code[^ ] space sets the mark] - .best[`^W` kill region] - .best[`^Y` paste 1st thing in the kill-ring] - .best[`M-Y` cycle the kill-ring] ??? OK I had to include a Meta-Y in there. Meta is alt or esc, there are many more interesting combinations. You actually had 'infinite' pasteboard since early Unices. --- # Copy/Paste - `Ctrl+insert` - copy - `Shift+insert` - paste - `Shift+suppr` - cut ??? That's [IBM CUA](https://en.wikipedia.org/wiki/IBM_Common_User_Access). They're in Unix, Windows, KDE/Gnome, Motif... Thanks Rubix for pointing this to me! --- # Special characters - `^I` tab - `^J` newline - `^M` newline? - `^V` verbatim - next char is literal ??? I'm not sure about ^J and ^M nuances. --- # I'm missing two letters! - `^X` I have no idea - try `^X^X` - BTW look at `cd -` & `pushd/popd` - Teletype shift i`^N`, shift `^O`ut ??? Seriously, teletype? Oh and ^X is probably extended commands, emacs-style, or... hey, I noticed this allows me to have two cursors in a line and go back and forth. `pushd`, `popd`, `cd -` style --- # Depending on - `sh` - `$EDITOR` ??? Of course, tab-completion and shortcuts depend on your shell and editor. Oh my ZSH! --- # Alphabet - `SQ` - lock/unlock - .best[`CZ`, `fg`] - Processes - .best[`RGP`] - search - .best[`AEBF`] - moving - .best[`DLT`] - inputs - .best[`KUWH Y`] - killing / yanking - `IJMV` - special characters - `XNO` - super-special characters - now learn your punctuation `!!` `$?` ??? Unix terms are full of error codes, redo-commands, calling args back... You should definitely learn your Unix punctuation! --- class: center, middle, happy # Questions?       .b[[@abelar_s](https://twitter.com/abelar_s) - [@ParisRB](https://twitter.com/parisrb) - [@RailsGirlsParis](https://twitter.com/railsgirlsparis)] [maitre-du-monde.fr](maitre-du-monde.fr) .contrib[[Contribute to this talk on GitHub!](https://github.com/abelards/abelards.github.com/edit/master/talks/unix_shortcuts.html)] --- class: center, middle, happy # Thanks!       .b[[@abelar_s](https://twitter.com/abelar_s) - [@ParisRB](https://twitter.com/parisrb) - [@RailsGirlsParis](https://twitter.com/railsgirlsparis)] [maitre-du-monde.fr](maitre-du-monde.fr) .contrib[[Contribute to this talk on GitHub!](https://github.com/abelards/abelards.github.com/edit/master/talks/unix_shortcuts.html)]
