When you run a file as an executable (using either #! or fish <filename>), fish attempts to parse things that look like options (i.e., start with a dash), and fails if they are not valid options to fish.

The current behavior makes it impossible to pass dashed args to fish scripts intended to be executed directly (you must source them). This breaks, for example, the fish seq fallback when used with negative numbers (which has a bug with negative step values: I'll post a patch for that). This is how /bin/sh (and the like) behave: [EMAIL PROTECTED] ~> cat >test echo $@ ^D [EMAIL PROTECTED] ~> sh ./test -1 -2 -3 -1 -2 -3 [EMAIL PROTECTED] ~> sh -1 -2 -3 ./test sh: -1: invalid option Usage: sh [GNU long option] [option] ... ... If the arguments are before the file to execute, they are parsed as arguments to sh; if they are after, they are not parsed, but passed to the script's [EMAIL PROTECTED] -- Francis Avila ------------------------------------------------------------------------- Take Surveys.
