How to make GNU Find the default find inside scripts?

[mrjayviper]

So I installed GNU find via homebrew. I then created an alias called "find" and pointed it to GNU find.

    ~
    ➜  alias | grep find
    find=/usr/local/bin/gfind
    tree='find . -print | sed -e '\''s;[^/]*/;|____;g;s;____|; |;g'\'
    
    ~
    ➜  which find       
    find: aliased to /usr/local/bin/gfind
    
    ~
    ➜  find --version
    find (GNU findutils) 4.7.0

My problem is that inside a script (tried bash and ZSH), the script always wants to use the find command supplied by Apple when I use the "find" command.

Any ideas on how to fix? Thank you.

This is my sample script

    #!/bin/bash    

    source ~/Documents/environment-setup.sh
    alias | grep find
    which find
    echo "running find --version"
    find --version
    echo "running gfind --version"
    gfind --version

This is the output of the script

    ~
    ➜  ./test.sh
    alias find='/usr/local/bin/gfind'
    /usr/bin/find
    running find --version
    find: illegal option -- -
    usage: find [-H | -L | -P] [-EXdsx] [-f path] path ... [expression]
           find [-H | -L | -P] [-EXdsx] -f path [path ...] [expression]
    running gfind --version

I vaguely recall that aliases are for interactive use, not scripts. Refer to the bash man page, in its section on aliases. Here's an excerpt from one of my Mac's man pages:

Aliases are not expanded when the shell is not interactive, unless the​

expand_aliases shell option is set using shopt (see the description of​

shopt under SHELL BUILTIN COMMANDS below).​

The two alternatives that come immediately to mind are:
1. change your PATH variable.
2. define a shell function named find that runs /usr/local/bin/gfind.

bash will read from several different profile files, so you could edit one of those to change your PATH variable, placing /usr/local/bin before /usr/bin. You'd also need a hard-link or symlink in /usr/local/bin so 'find' is the same as 'gfind'.

A shell function named find can be defined in one of the bash profile files. It would basically be:

function find ()
{  /usr/local/bin/gfind "$@"; }
