I like to make life easy so I wrote a one-line script for extracting the
contents of a tar file. I copied it into the /bin directory so I can run
it from anywhere.

Why doesn't it work from bin/ ?

I just found out that I have an alias called tarx in
my .bashrc. In fact, someone asked me about this and
I answered in the negative, without checking. My apologies!

 
Apology accepted. :-)
 
Glad you found (and presumably fixed) your problem.

 
 
What command would show what exact incantation is used? Ie, what
path/binary, or what alias?
 
which tarx?

But it is an alias in my system

 
This depends on the shell...
 
marchhare% which dir
dir:     aliased to ls -F -C
marchhare% echo $SHELL
/bin/tcsh

 
16:22:25 $ echo $SHELL
/bin/bash
 
16:22:28 $ alias
alias tarx='tar -xf'
 
bash(1) says
  "Aliases are created and listed with the alias command,
   and removed with the unalias command."

POSIX says
  "A valid alias name shall be one that has been defined by
   the alias utility and not subsequently undefined using
   unalias."
   (https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_03_01)
and further says (in regard to the alias utility)
  "The alias utility shall create or redefine alias definitions
   or write the values of existing alias definitions to standard
   output."
   (https://pubs.opengroup.org/onlinepubs/9699919799/utilities/alias.html)

So, it appears that bash conforms to POSIX requirements with
respect to the behaviour of it's "alias" builtin command.
