Good idea. ruby seems to work the same way. python does too but with a slightly different definition:
C:\> ruby -h | findstr strip -x[directory] strip off text before #!ruby line and perhaps cd to directory C:\> perl -h | findstr strip -x[directory] strip off text before #!perl line and perhaps cd to directory C:\> python -h | findstr skip -x : skip first line of source, allowing use of non-Unix forms of #!cmd On 1/26/07, Vladimir Eremeev <[EMAIL PROTECTED]> wrote: > > ActivePerl has '-x' switch which tells it to skip all lines in the file till > "#!". > This allows writing perl scripts in ordinary .bat files. > > ?shQuote contains a link with the following perl script example: > ===8<=== > @echo off > :: hello.bat > :: Windows executable Perl script > :: Note: > :: assumes perl.exe is in path > :: otherwise, use absolute path > perl -x -S "%0" %* > goto end > #!perl > > print "Hello, World!\n"; > __END__ > :end > :: ------ end of hello.bat ------ > > Windows Notes: > " -x " (lower case x): Skip all text until shebang line. > " -S " (upper case S): Look for script using PATH variable.
