macOS bash not finding program

[dancks]

I know that in order to find to program either the proper path or the path needs to be a part of the $PATH variable.

I'm trying to set up homebrew. its in /usr/local/bin because it refuses to run in /usr/bin for some reason. Thing is unless I specify /usr/local/bin/brew it will give me:

-bash: /usr/bin/brew: No such file or directory

Why does this happen?

Does the fact that I set it up (and then removed from) /usr/bin make a difference? why? if it doesn't look through every specified path in $PATH, then what is $PATH for?

So is /usr/local/bin in your path?

This seems pretty obvious, am I missing something here?

Yes it is. Thats why I was confused.

Please post the exact command you gave that elicited the message:

-bash: /usr/bin/brew: No such file or directory

Also post the exact value of PATH at the time you gave the command.


If there used to be a command 'brew' located in /usr/bin, and you removed it, but haven't started a new shell, then bash probably thinks that /usr/bin/brew still exists, because bash hashes the directories listed in PATH. That is, bash scans the directories in PATH, builds an internal hashtable, then looks up command-names in the hashtable expecting to quickly discover which directory to run the command from.

See here:
https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/bash.1.html
then find the word hash on that page.

You can tell bash to rehash the directories in PATH (see hash under SHELL BUILTIN COMMANDS at the above link).


Enter this command, and post the complete output (if any):

type -P brew ; type -a brew

me:~me$ brew

is what caused the output in question.

the other stuff:

me:~me$ type -P brew; type -a brew
/usr/local/bin/brew
brew is /usr/local/bin/brew

me:~me$ echo $PATH
/opt/local/bin:/opt/local/sbin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/sw/bin:/sw/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin:/usr/texbin:/usr/X11/bin
me:~me$

You were right about the shell hash thing. Thanks. Now if I could only find a way to update X11 library on 10.6 I'll be golden.
