OSASCRIPT(1) General Commands Manual OSASCRIPT(1)
NAME
osascript – execute OSA scripts (AppleScript, JavaScript, etc.)
SYNOPSIS
osascript [-l language] [-i] [-s flags] [-e statement | programfile]
[argument ...]
DESCRIPTION
osascript executes the given OSA script, which may be plain text or a
compiled script (.scpt) created by Script Editor or osacompile(1). By
default, osascript treats plain text as AppleScript, but you can change
this using the -l option. To get a list of the OSA languages installed on
your system, use osalang(1).
osascript will look for the script in one of the following three places:
1. Specified line by line using -e switches on the command line.
2. Contained in the file specified by the first filename on the command
line. This file may be plain text or a compiled script.
3. Passed in using standard input. This works only if there are no
filename arguments; to pass arguments to a STDIN-read script, you must
explicitly specify “-” for the script name.
Any arguments following the script will be passed as a list of strings to
the direct parameter of the “run” handler. For example, in AppleScript:
a.scpt:
on run argv
return "hello, " & item 1 of argv & "."
end run
% osascript a.scpt world
hello, world.
The options are as follows:
-e statement
Enter one line of a script. If -e is given, osascript will not look
for a filename in the argument list. Multiple -e options may be
given to build up a multi-line script. Because most scripts use
characters that are special to many shell programs (for example,
AppleScript uses single and double quote marks, “(”, “)”, and “*”),
the statement will have to be correctly quoted and escaped to get it
past the shell intact.
-i Interactive mode: osascript will prompt for one line at a time, and
print the result, if applicable, after each line. Any script
supplied as a command argument using -e or programfile will be
loaded, but not executed, before starting the interactive prompt.
-l language
Override the language for any plain text files. Normally, plain text
files are compiled as AppleScript.
-s flags
Modify the output style. The flags argument is a string consisting
of any of the modifier characters e, h, o, and s. Multiple modifiers
can be concatenated in the same string, and multiple -s options can
be specified. The modifiers come in exclusive pairs; if conflicting
modifiers are specified, the last one takes precedence. The meanings
of the modifier characters are as follows:
h Print values in human-readable form (default).
s Print values in recompilable source form.
osascript normally prints its results in human-readable form:
strings do not have quotes around them, characters are not
escaped, braces for lists and records are omitted, etc. This is
generally more useful, but can introduce ambiguities. For
example, the lists ‘{"foo", "bar"}’ and ‘{{"foo", {"bar"}}}’ would
both be displayed as ‘foo, bar’. To see the results in an
unambiguous form that could be recompiled into the same value, use
the s modifier.
e Print script errors to stderr (default).
o Print script errors to stdout.
osascript normally prints script errors to stderr, so downstream
clients only see valid results. When running automated tests,
however, using the o modifier lets you distinguish script errors,
which you care about matching, from other diagnostic output, which
you don't.

HISTORY
osascript in Mac OS X 10.0 would translate ‘\r’ characters in the output to
‘\n’ and provided c and r modifiers for the -s option to change this.
osascript now always leaves the output alone; pipe through tr(1) if
necessary.
Prior to Mac OS X 10.4, osascript did not allow passing arguments to the
script.
