Command not found

Question

Hi i'm going to create one script (.sh or .command) my Script is

  #!/bin/bash
  echo Build Begin
  'xcrun instruments -w "iPhone 5s (8.3 Simulator)"'

i got error,

  Last login: Mon Mar 21 15:48:29 on ttys000
  MacBook-Pro:~ user$ /Users/user/CommandWorld.command ; exit;
  Build Begin
  /Users/user/CommandWorld.command: line 3: xcrun instruments -w "iPhone 5s (8.3 Simulator)": command not found
  logout

  [Process completed]

If i run command "xcrun instruments -w "iPhone 5s (8.3 Simulator)"" as it is on terminal then its worked ... but why it not in script file?

Answer 1

By putting the whole command inside single quotes, you make the shell assume it is a single word ; it then expects to find a command that match it, rather than the command xcrun . Remove the single quotes and you should be alright.

The double quotes are here for the same purpose (and should not be removed) : to pass "iPhone 5s (8.3 Simulator)" as a single word rather than a list of words ( iPhone , 5s , (8.3 and Simulator) ).
