Changelog

This changelog includes all notable changes to the which.sh project.

Unreleased

Fixed

  • The oversight in cleanup script. By design if the script fails to change the working directory to dev before starting the cleanup routine, it should abort with the statement "Fatal: unable to change current working directory to dev" on /dev/stderr, but this could never happen due to the missing directive exit 1 next to the above report
  • A number of grammar typos in readme
  • Broken 404 link at the first sentense of Preamble. The link has been pointing to src/which.sh instead of src/which.classic.sh ʼcause it has been initially added to the readme upon the old project tree structure which turned obsolete on which on steroids arrival

2.0.0 - 2024-07-09

Added

  • Extended edition of which function. Implemented as kinda successor of the classic edition which delivers the extra feature to locate command(s) among shell builtins, functions and aliases
  • Option -i to ignore shell builtins, functions and aliases on lookup for extended edition of which function
  • Test suite for thorough testing of both editions against the bunch of 23 shell interpretters which meet POSIX specification and are available for Linux and Darwin (macOS) platforms nowadays
  • Dedicated tests runner to rule test suite
  • Cleanup script for optional use when the tests are over
  • Detailed readme covering each nuance of both editions
  • MIT license
  • Special shortcut links juliyvchirkov.dev/get/which.sh to get the latest release of classic edition of which function and juliyvchirkov.dev/get/which.sh?ed=ext to get the latest release of extended one

Changed

  • Initial function has been totally revised and redesigned from scratch to mimic the external classic which command as close as possible
  • A number of commands to locate at arguments has been increased from the one and only to the unlimited (one can get the actual limits of a system with GNU xargs thru xargs -r --show-limits </dev/null)
  • Each report line for a located command is now ended with line feed \n
  • Option -a has been implemented to report all matches for located command(s) instead of the default first one
  • Option -s has been implemented to locate command(s) silently with no report(s) to /dev/stdout
  • Extra exit status code 2 has been added to indicate an invalid option
  • The corresponding detailed help is provided when the function is launched with no arguments or an invalid option is specified

Fixed

  • The oversight at PATH parsing subroutine due to which the function has been unable to locate a command if a path of that command contains space(s)

1.0.0 - 2018-04-23

Added

  • First public release of which function (initially published as gist)
