Get full path of script in PATH environment variable

bashterminal

I was wondering if there is a built-in command in Bash (or even something OSX-specific) that would display the fully resolved path of a script that is in the current PATH environment variable.

For example, my PATH currently looks like this:

>: echo $PATH | tr ":" "\n"
/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin
/opt/X11/bin
/Users/Josh/Dropbox/Scripts/Bash
/Users/Josh/Dropbox/Tools/WinRAR/OSX

And there's a script in Dropbox called get-azurelogs.sh. That path is in my PATH variable for convenience, but if I wanted to display the complete path to that script, assuming I wasn't sure where it was, is there an simple one-liner way to display the fully resolved path instead of testing it at each of the directories above?

You can use which. From the man page:

The which utility takes a list of command names and searches the path for each executable file that would be run had these commands actually been invoked

Your question is unclear as it seems to ask several things. However the issue re launching from the Dock can be answered.

The Dock does not call a shell. .profile and other startup scripts are only run when Terminal.app or similar starts a shell or you run a shell script via launchd etc.

To change the path used for Apps launched from the Dock, Finder or other GUI then you need to change the path your Workspace uses this is in ~/.MacOSX/environment.plist e.g. mine is

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>WAFDIR</key>
  <string>/Users/mark/src/third_party/git-svn/waf</string>

  <key>PATH</key>
  <string>/Users/mark/bin:/Users/mark/env/bin:/Users/mark/usr/local/bin:/usr/local/bin:/opt/local/bin:/usr/local/git/bin:/bin:/usr/bin:/sbin:/usr/sbin:/usr/X11R6/bin:/usr/libexec/binutils:</string>
</dict>
</plist>

Also have a look at this question.

MacOS – Characters do not echo in OS X terminal unless I hit the delete key

Your prompt is messed up, specifically PS1:

PS1=$[\033]0;37m]

that's missing a lot of escape characters (\e[) needed for the colors (and most useful parameters for a PS1). That's also why you get the 37m in the terminal window title. Try setting it to something different by running:

export PS1="\e[0;31m[\h:\W \u]\$\e[m "

and see if that works. It should give a red (thats \e[0;31m) prompt showing hostname (\h), current working directory (\W) and logged in user (\u) inside brackets [] and the bash exit status of the previous command (\$). Note that at the end the color is reset to the default of the session with \e[m .

If the above worked, you only have to find out from which configuration file your "bad" PS1 comes from: look for an "export PS1=" line in ~/.profile, ~/.bash_profile, ~/.bashrc, (as M K already suggested in his answer) and put in the above version.

There are a lot of answers around here with helpful colors codes and inputs for configuring the PS1, like this one for example.
