What UNIX Shell Config Settings Work for Newbies? 159

Posted by Cliff from the tab-completion-is-your-friend dept.
Human_Diastrophism asks: "I'm involved in the roll-out of a new *x-based computing service in my previously Windows-centric organization. I want things set up so that newcomers will understand and like what they see. They should feel encouraged to behave appropriately, i.e. explore and extend the environment for themselves. We're talking about technically literate folk who are simply new to the demands and freedoms of the command line. No shell advocacy, please; it's going to be ksh or bash. What would you put in a .profile or .rc to make things work smoothly and give the user the capabilities and feedback they need? I'm thinking about stuff like 'stty erase ^H' and 'set -o emacs' so the edit keys work, and a compact but informative prompt. But what else would you put in? What would you leave out?"

    Some good stuff in previous posts about aliasing DOS commands to translation messages and commenting the .bashrc to be helpful.

    Additionally, make *sure* their home, end, backspace, delete keys work properly. I'm not sure if we're talking pure command line or xterm (it's more an issue with some distros and xterms) but it's a hell of a lot to figure out when it's busted and a hell of a pain for a Windows user. It's not exclusively a shell issue but relates to the CLI experience.

    And I'd recommend *not* aliasing 'rm' to 'rm -i' because they're going to get sloppy and be really annoyed when they move to a box that doesn't have that set up and wipe stuff out.

    Set up their pager with something nice like 'export LESS="-eFMRXj12"' (well, it's nice to me).

    Stuff like 'shopt -s checkwinsize cmdhist extglob histappend histverify [etc]' - histverify is cool for new people not popping off the wrong command by accident when they're playing with the cool history tricks.

    Basically, keep it simple - avoid extremely dangerous things like giving them a fuzzy concept of 'rm' and enable not-particularly-dangerous things like 'histverify'. But make sure things like their keyboard and display work like they expect - most important thing. Then just give some hints and enable them to explore for themselves.

    You said no shell advocacy, so I won't recommend zsh, but something like its tab-completion mechanism would be a really good idea. I believe some packages exist to give bash similar abilities, and I would highly recommend installing them.

    Good tab completion makes using the command-line much easier for novice users, once they get the idea that any time they aren't sure what to type, they should just hit TAB. Don't remember the options to "ls"? Just type "ls -" and you'll get a nicely formatted summary. Don't remember the name of the directory you want to "cd" into? Just hit TAB and you'll get a list of the directories (not files!) in the current directory.

    And good tab completion knows about lots more than just the shell builtins or common commands. It knows all about *lots* of command-line tools, their options, what types of files are reasonable parameters for them ("gqview " gives a list of IMAGE files and directories in the current directory, omitting any non-image files from the list -- gqview is an image viewer), etc. zsh tab completion even knows how to look at remote systems to get completion info. For example, typing "scp 10.0.1.1:f" gets me a list of the files on my home directory on my Linux router that begin with "f". If there's only one, it gets expanded for me.

    Even when smart tab-completion can't tell you what to type, it often gives you a good hint. I think that would be very helpful to (smart, computer-savvy) command-line newbies.

  • Just so you don't get forlorn people asking about how to undelete things, retrieve them from wastebaskets, etc., you might want to alias rm, mv, cp to use the -i option.

    Later, after they get tired of answering yes they can learn how to edit their profile and remove the training wheels.

    [Even then, I hope you have a good automated nightly backup running on the user's home directories.]

  • This solves most backspace/delete problems for me when using terminal based apps such as vi.
  • Whatever else you do, alias cp, rm, and mv to always include -i (for confirmation)!!!

    And set them up with a shell prompt that shows username, host, and current directory.
    • alias -x xterm='xterm -ls -sb -rv'
    • alias -x psg='ps ax | grep'
    • alias -x bye='clear;exit'
    • alias -x ssh='ssh -X'
    • HOST=`hostname -s`
    • if [ "X${TERM}" == "Xxterm" ]; then
      alias -x vi='vim -T xterm-color' alias -x cd='Xcd'
      Xcd()
      {
      if [ $# -ne 0 ]; then
      'cd' "$@"
      else
      'cd'
      fi
      echo " ^[ ]0;${HOST}:${PWD} ^G "
      }
      Xcd .
      fi

    I never finished the Xcd() function to perfection, but it generally does what I want. Note that the ^[ and ^G are binary, 0x

  • Shells are a personal thing, and trivial to install and change. Make whichever you want default, but let the advanced users change shells. You might hire an old school Unix guy, like me, who likes his own personal shell. Make sure it is there. Not the default, but there for advanced users.

    csh/tcsh is a must, because it is different and some people prefer it. (I still can't wrap my mind around bash, not that I've tried)

    Install the adventure shell, because someone will want to try it.

    It depends on how much effort you want to put into it, but here are some more suggestions.


    No matter what, make it absolutely clear whenever they use something that can bite them hard on a normal terminal. Don't train them to fail later. Aliasing 'rm' to 'rm -i' can hurt them bad when they get used to typing 'rm *' to be prompted for which files to delete.

    If you want to get really advanced, include two scripts that will switch them to 'normal' mode or back to 'training' mode.

    Start them out in training mode. When they log in, they get:
    * an entire screen of help, including the command to leave training mode, and listing the safety nets you added.
    * their prompt contains "(TRAINING)" or "(NEWBIE)" or something
    * alias 'rm' to 'rm -i', etc.
    * any other safety nets
    * point out 'grep', 'find', 'head', 'tail', 'less' and the cute little 'wc' and where to discover more about unix commands.

    When they switch to normal mode, after confirmation, their login only includes the command to return to training mode. (Which they can edit out of the .bashrc) And their prompt doesn't have "(TRAINING)" in it anymore.

    The idea is that you make sure that they know which safety nets you create, that aren't on other systems. They also get a transistion period for as long as they want. Leaving the "TRAINING" in the prompt is a continual reminder that there setup is more 'safe' than other systems, and may add motivation to go into normal mode.

    The rest of this is from my tcsh experience:

    * set up 'complete [freshmeat.net]' options for common, yet complex commands like 'find', 'alias', 'set', 'man', 'nethack'. (very cool in tcsh [freshmeat.net], is this feature in bash?)

    * alias l=ls, ll=ls -l, la=ls -a (doesn't hurt anyone)

    * set tab to autocomplete or list matches, if it doesn't already

    * include apache-style comments (maximum verbosity) inside the .bashrc

    * set prompt to "(time) :: (path)\n(host) {(#)}% " (don't know bash)

    * don't alias any DOS commands directly to Unix except for 'dir'. Alias the others DOS commands to mini-helps that remind them gently to use the proper Unix command.

    * use nano

    Second, setting up a bunch of "-i" aliases is an extremely bad idea for newbies. Considering that they're starting with a blank slate, this is the time when they can most afford to learn that the machine will always do what t

    • I've found that, in bash, when all of thgose fancy completions are turned on it borks globbing with * wildards. For example, ls /home/collin/.*ash*[tab][tab] gives me a list of matching files, but when I turn all of the nifty bash tab completion features on it no longer gives me anything.

    I'd like to suggest using joe -- it's a nice editor with a good user interface (in that it's easy to figure out how to use based on the interface, without resorting to man pages/tutorials/etc.). It's got a PICO emulation (invoked with "jpico") for those who insist on using keybindings from a badly licensed editor, but offers more commands than PICO and clones.

    The prompt should take the form "user@host:path % " - this is particularly important in environments with multiple machines, and a good idea anyway.

    The shell should be set up for command-line editing (BASH comes this way IIRC, in KSH set -o emacs.
