/filter [-asdfkwxnpriocteubglLz] [n-n2] [c s] <infile | dialog id> <outfile | dialog id | alias> [alias] <matchtext>

Scans lines of text in a window, file or dialog control, any matches are then written out to another window, file, or dialog control.
The order of the switch are important, they define what is the infile and what is the outfile, see the examples for more information.

You can filter blank lines by specifying $crlf for the matchtext.

The $filtered identifier will retrieve the number of matches found.

Switches

-w - Indicates the parameter is a window.
-f - Indicates the parameter is a file.
-a - Sorts filtered lines by calling the optional [alias] parameter, the alias is passed two lines, $1 and $2, it must compare both and return -1, 0, or 1 to indicate relative sort order of these lines to each other.
-x - Excludes matching lines.
-n - Prefixes lines with a line number. (the Nth match)
-d - TODO
-s - Indicates the status window will be used.
-p - TODO
-r - Specifies the range of lines n to n2 for filtering.
-b - Strips BURK codes when matching text.
-g - Indicates the matchtext is a regular expression.
-z - TODO
-k - Indicates that you have specified an <alias> as the output instead of a window name. The alias will be called with the result of each filtered line with the form $<alias>($1) where $1 is the matched line.
-i - Indicates that you have provided a [dialog id] custom dialog control as the input.
-o - Indicates that you have provided a [dialog id] custom dialog control as the output.
-c - Clears the output window/file before writing to it.
-t - Sorts the output based on [c s], column C using character S as the columns separator.
-e - Used with -t, specifies a descending sort.
-u - Used with -t, specifies a numeric sort.
-l - Filters from the side-listbox in the first window.
-L - Filters to the side-listbox in the second window.

Parameters

[n-n2] - if -r is used, indicates the range of lines to be scanned*
[c s] - if -t is used, indicates how to do the sort
<infile | dialog id> - if no switch implies a window's name to be use as the infile, you must provide an infile (a window, a file, or a dialog control)
<outfile | dialog id | alias> - if no switch implies a window's name to be used as the outfile, you must provide an outfile (a window, a file, a dialog control, or an alias name if -k is used)
[alias] - optional alias called if -a is used
<matchtext> - the expression used for the search, if $null is used, it matches everything.
