Start all of your commands with a comma (2009) (rhodesmill.org)

This is a good trick to avoid collisions with system commands. Anytime you add one of your own executables to PATH, prefix it with a comma (,). This way you avoid name collisions and have a handy way of seeing what commands are available on your system using tab completion (, then tab lists all of your personal executables)

Cool.

I have a script that creates new ~/bin scripts that checks for collisions locally (functions, builtins, and executables) and in linux distros.

For example, I have a ~/bin/up script on every box and platform to install updates. So far so good on collisions.

Clever trick. Too bad there's no good way to namespace commands. It would be interesting if you could have, for instance:

  $ mkdir -p /tmp/bin/my
  $ printf '%s\n%s\n' '#!/bin/sh' 'echo hello' > /tmp/bin/my/hello
  $ chmod 755 /tmp/bin/my/hello
  $ PATH="/tmp/bin:$PATH"
  $ my/hello
  hello

    ,my,hello

    $ touch foo::bar
    $ chmod +x foo::bar
    $ ./foo::bar && echo $?

    $ alias +x='chmod +x'

    $ export $MY = /tmp/my
    $ $MY/hello
    hello

  my hello

  $ my hello

I use this method for aliases in my `.*rc` file so I can remember what the heck I called things. Otherwise, I forget whether I have to type something like `COMMANDNAME-log` or `log-COMMANDNAME` or some other weird combo like `print-COMMANDNAME-log`. With a comma, I type `,<tab>` and get all of my custom commands listed easily.

If I unknowingly named my command the same as some system command and the custom command ends up earlier in my path it doesn't really cause any problems does it? I wasn't using that system command anyways, and my custom command is only going to take priority if my .bashrc file was run first.

    env > "$(date +s).env-snapshot"

    <$file | xargs -I@ echo '"@"' | tr '\n' ' ' | xargs -I@ env @ cmd

  <$file xargs ...

  $ <xyz.txt wc -l
         8
  
  $ <xyz.txt | wc -l
         0

I have used a similar windows trick. I wanted to add to the default window system a place for my library of tools. Most are "portable" cmd apps from various sources (sysinternals, nirsoft). I put them all into a directory called ] in the root of a drive.

Because of some common layout of keyboards the \ and ] are near each other, or in reach of left and right pinkies I can type \]\ before the name of the tools. This means I don't even have add a dir to the path.

I am sure this violates someone sensibilities but it has saved time over the years as a consultant when I had to deal with a wonky machine and owner did not want permanent install of diagnostic tools.

I do basically the same thing with any aliases or commands that I have just for me. Except I prefix with _ (an underscore.) Having some sort of prefix is extremely nice as it ensures you never override a built-in on accident, AND it makes it easy to tab complete just the ones that you want.

For example I have ‘_f’ aliased to a fuzzy find command that will launch vim on the selected files, and a different one for launching sql clients to various servers etc.

As a prefix, commas work great!

This brought https://github.com/Shopify/comma to mind

In the comments, the author argues against the underscore by saying Bash/Zsh already uses it for completion. But it looks like it's a Zsh thing - at least my Bash install is pretty conservative about it.

Is it secure to have ~/bin/ it the PATH?

I tend to give programs longer, more descriptive names and then do the short names as shell aliases. That way there’s little risk of name collision for the original program, scripts using the canonical name remain readable, and the shorthand is free to evolve to fit varying work habits.

I do something a bit special... Instead of naming my script foobarnator (and hence risking that another foobarnator may exist in the future and may clash with my script), I name my script foobarnatorToBeAliased.sh. Then in my list of aliases I alias foobarnator to foobarnatorToBeAliased.sh.

The alias itself looks a bit weird in that to pass arguments to an aliased command you need to use a function (in Bash at least AFACIT) but it all works fine.

As aliases aren't sourced when other scripts are running, I'm sure my scripts/commands ain't ever going to clash with anything.

I've been doing that since years.

It also works fine to add "wrappers" to existing commands: for example to add additional input sanitization catching common mistakes I'm making when calling some commands.

    function ,foo() { printf "Fooo\n"; }
    ,foo

    $ alias say=echo
    $ say beep
    beep

    alias watch='watch '

    alias beep=echo
    watch beep hello # This will fail
    alias watch='watch '
    watch beep hello # Now it works!

Cool.

I’m gonna start them with `å` just to be a little different.

I've never once had a problem with one of my commands shadowing a system command so I think I will continue on rather than solving this non-problem, thanks.

clever idea, but does it need such a long post to describe?

I almost always add "," in cmd.exe to anything I run from Windows Command Prompt? Why? Because cygwin, or mingw's `dir.exe` would be called instead of built-in dir (well, this is further complicated that I don't really use `cmd.exe` but FAR Commander), so if I want to enforce the built-in over external (same name) command I have to prepend it with "," - so I basically started typing "," in front of each of my commands...

I do something similar but 1. for aliases and 2. use period. For example, when working on a Rails project I define the following alias:

    function .routes() {
      if [[ $# -eq 0 ]]; then
        .rails routes
      else
        .rails routes | grep $@
      fi
    }

where .rails is another alias (for running bundle exec rails ...). I can then run ".routes webhook" and see all routes containing "webhook".

Last but not least, I automated the whole thing with bash-ctx (https://github.com/gregnavis/bash-ctx).

I just add the .sh suffix/extension to them... And I use j- as prefix for the "tab trick"

The comma is employed in bash and other shell for brace expansion.[1] I can't see how this would conflict with OP's master plan, but I have fundamental objections towards the depths of OP's laziness. Lazy is ok, but there should not be competition to see who can be laziest. At some point, things just won't compress any further, and the attempt at further streamlining efficiency beyond what is useful has a negative effect on efficiency overall. Besides, tab completion is fine as it is and doesn't need what passes for a hack these days. To be clear, contrary to what OP has claimed about not being creative enough to come up with original script names that won't conflict with the flood of new Linux commands every update (wot? LOL), this is only about the OP not being satisfied with tab completion.

I do the same thing but with prefix …

Commas can also be used in filenames to help you sort things instead of using underscore as a separator, useful for the same reason -- you don't have to hit shift to type it.
