I just wrote this in the Terminal when my girlfriend was there : say "I love you" She was impressed :)

Well, since I can't comment on that convoluted site, a quick gotcha with 'pbpaste' and 'pbcopy': they don't work with screen. EDIT: This issue no longer exists. Kindly ignore my comment.
- jcromartie 16y ago
  I always use screen and I use pbcopy/pbpaste all the time. What about them doesn't work?
  - jherdman 16y ago
    You've made me second guess myself. I was getting bit by this bug http://trac.macports.org/ticket/18235 http://trac.macports.org/ticket/18235. It does not persist any more. Apologies.

  my latest nifty screen trick (borrowed from a similar variant for xclip) goes: bindkey -m > eval "stuff ' '" writebuf "exec sh -c 'pbcopy < /tmp/screen-exchange'" then when you've made a selection in screen Copy Mode, just terminate it with '>' to stick it onto the system paste buffer.

http://superuser.com/questions/52483/terminal-tips-and-tricks-for-mac-os-x/152190#152190 http://superuser.com/questions/52483/terminal-tips-and-trick... doesn't work for me; it seems I can hold ESC for arbitrarily long without evoking Terminal's interest. I'm using the Vi keymappings (set -o vi), so I guess that's no surprise; but is there a Vi equivalent?

  If you're using bash as your shell, <TAB><TAB> should do the trick.
  - JadeNB 16y ago
    Ah, silly me. Somehow I read “only built-ins” instead of “including built-ins”, and so thought that it was something more than (or at least different from) ordinary tab-completion.

I love "mdfind" for near-instant file searching. "mdfind -name AppName" is a good start for a poor man's uninstaller on OS X.

  For uninstalling things, pkgutil is a useful tool to know about. You can list all installed packages with pkgutil --pkgs and uninstall them by doing pkgutil --unlink pkgid I wondered for a long time how to uninstall packages from OS X until I discovered pkgutil.

Full emacs keybindings: A lot of key emacs bindings--C-a, C-e, C-n, C-p, C-f, C-b--work in any text field (even, say, the Hacker News comment box). But M-f and M-b (which are really useful since they get you forward/backwards a word instead of just a letter or a whole line) don't work. When I try to type option and then a letter, I get weird symbols: Here's option-b: ∫ Here's option-f: ƒ To get make M-f and M-b work, go to Preferences->Settings->Keyboard and check the "Use option as meta key" box. See http://skitch.com/jackowayed/dme91/terminal-fix-keybindings http://skitch.com/jackowayed/dme91/terminal-fix-keybindings if you can't find it.

  And of course for standard moving around: ←/→ move left or right one character. ⌥ + ←/→ move left or right one word. ⌘ + ←/→ move to start or end of line

    What's even better is that these can be customized: http://news.ycombinator.com/item?id=448218 http://news.ycombinator.com/item?id=448218

    and while holding down shift, the selection is extended in those ways as well.
- JadeNB 16y ago
  It has nothing to do with Terminal.app, but I consider the ease of making those symbols one of the nice things about text entry on a Mac—I miss it sorely on Ubuntu (where I'm sure the equivalent exists, but (1) I don't know it and (2) it likely requires memorising code points). You can see which keystrokes will produce which funny symbols by turning on Keyboard Viewer (under Input Menu, which itself can be turned on from the International tab under System Preferences.app; or there's probably some way to invoke it directly).

I use Visor, which is a quake-style dropdown terminal plugin for Terminal. It takes up a Terminal window, but doesn't interfere with other such windows. There's a plugin for Terminal that implements copy-on-select, which I like, but Visor has it bundled, so I'm not sure what it's called, offhand.

fish should come as the default shell in OS X: http://fishshell.org/screenshots.html http://fishshell.org/screenshots.html It's more user friendly and interactive.
- Dobbs 16y ago
  Possibly but at the same time most people who will be using the terminal at all on Mac are the same people who have been using the terminal on linux. For people that have been using the terminal on linux Bash is more user friendly (it is what they already know).
  - div 16y ago
    By that logic, windows is more user friendly then OSX because it is what people already know. Most of the stuff you would use in bash just works in fish as well, except that fish gives you nice help information when tabcompleting, a better command history that you can use filters on, colour feedback (red = invalid command, green is a-okay) and lots more. Sure, some people will always stick to what they know, but that does not say as much about user friendliness as it does about resistance to change.

  An interesting github project I recently discovered on github has some nice fish extensions, it's called fish-nuggets and you can find it here: http://github.com/zmalltalker/fish-nuggets/ http://github.com/zmalltalker/fish-nuggets/ Here's a pic of it showing branch@revision status for svn repositories: http://tweetphoto.com/29802557 http://tweetphoto.com/29802557 It does the same for git repositories as well and some other nice stuff.

    See also zsh, another great shell that gets little attention. Recent versions of zsh (though not the version that ships with OS X) have a feature called vcs_info that will pull information from git, svn, cvs, hg, darcs, bzr (& more) for use in your prompt. http://www.zsh.org/mla/users/2008/msg00842.html http://www.zsh.org/mla/users/2008/msg00842.html

One of the commenters mentions the `say` command, which is super-useful, but they use it like so: `scp file some-host:~; say 'copy done'`, which will notify you even if the command fails. You should use && so the notification only happens on success, or conditionally say something else. I use this constantly in deploy, etc, scripts so I can run my compile + rsync + deploy command in a terminal, background it, and go work on something else until the process finishes. I'd say it's generally useful for anything that takes longer than 10 seconds but less than an hour (after an hour you tend to forget what's going on; might as well just email yourself.) Festival (http://www.cstr.ed.ac.uk/projects/festival/ http://www.cstr.ed.ac.uk/projects/festival/) is something similar for *NIX users.
- mhansen 16y ago
  If you can't get festival to work (it wouldn't for me), 'espeak' worked great on my Ubuntu box.
  - PidGin128 16y ago
    I remember issues arising due to weird default permissions when I tried to use beep, or bell (don't remember if it was the command or character [ctrl+g]). I think festival or the command used to play the startup sound in ubuntu where the easiest alternatives, as getting beep/bell to work is weird. Pre-Edit: /usr/bin/canberra-gtk-play , according to my Ubuntu's startup applications preferences.

Anyone know how to open a new tab in OS X Terminal to have the same path as the previous tab? This is sort of a default behavior in Linux OSs and it's really annoying when you have to `cd` to the working path every time you open a new tab.
tel 16y ago
My favorite trick is using DTerm[1] to hybridize graphical and textual interactions. More of a meta-Terminal trick, with a keyboard command it brings up a floating input for terminal entry with some intelligence to the context you initialize it from. Common uses include starting up Terminal with a command instead of just carte blanche, using a globbed rm to clean a folder I'm viewing in Finder, using ls/grep to find files in a current Finder window, &c. &c.
