@ -54,3 +54,7 @@ Ksh automatically searches FPATH for any command not found in PATH, and
|
||||
autoloads the file if found. The "autoload" command is only required if
|
||||
you want FPATH to be searched before PATH, e.g. because the function has
|
||||
the same name as a command in PATH.
|
||||
|
||||
All parameters in ksh are indexed arrays. That's why $array has to mean
|
||||
${array[0]}, and why subscripts can't be used to extract substrings from
|
||||
scalars.
