4.20 OS Package

The BUSH OS package contains miscellaneous operating system routines.

i := os.status

Return the the least operating system exit status. (To set the exit status, use command_line.set_exit_status.)
Example: if os.status /= 0 then put_line( standard_error, "error!" ); end if;
Ada Equivalent: none (AdaScript extension)
Parameters:

s := os.strerror( i )

Return the operating system string error message for error number i.
Example: put_line( os.strerror( 15 ) );
Ada Equivalent: none (AdaScript extension)
Parameters:
s result string required the error message (e.g. "Operation Not Permitted")
i in integer required the O/S error number (e.g. 1 )

os.system( s )

Run an operating system command in the default shell. This is the same as the C system() function. Use os.status to determine the exit status.
Example: os.system( "ls" );
Ada Equivalent: none (AdaScript extension)
Parameters:
s in string required the sound shell command to execute
