This works (prints, for example, “3 arguments”):

to run argv     do shell script 'echo ' & (count argv) & ' arguments' end run

This doesn’t (prints only “Argument 3: three”, and not the previous two arguments):

to run argv     do shell script 'echo ' & (count argv) & ' arguments'      repeat with i from 1 to (count argv)         do shell script 'echo 'Argument ' & i & ': ' & (item i of argv) & '''     end repeat end run

In both cases, I’m running the script using osascript on Mac OS X 10.5.5. Example invocation:

osascript 'Script that takes arguments.applescript' Test argument three

I’m not redirecting the output, so I know that the script is not throwing an error.

If I add a display dialog statement above the do shell script, it throws a “no user interaction allowed” error, so I know that it is executing the loop body.

What am I doing wrong? What is it about this loop that causes osascript to not print anything?

  1. Try this to avoid having to use the temporary file.

    to run argv         set accumulator to do shell script 'echo ' & (count argv) & ' arguments' altering line endings false         repeat with i from 1 to (count argv)                 set ln to do shell script 'echo 'Argument ' & i & ': ' & (item i of argv) & ''' altering line endings false                 set accumulator to accumulator & ln         end repeat         return accumulator end run
