tcl7.6 User Commands - lsort
NAME
lsort - Sort the elements of a list
SYNOPSIS
lsort ?switches? list
DESCRIPTION
This command sorts the elements of list, returning a new
list in sorted order. By default ASCII sorting is used with
the result returned in increasing order. However, any of
the following switches may be specified before list to con-
trol the sorting process (unique abbreviations are
accepted):
-ascii Use string comparison with ASCII colla-
tion order. This is the default.
-integer Convert list elements to integers and
use integer comparison.
-real Convert list elements to floating-point
values and use floating comparison.
-command command Use command as a comparison command.
To compare two elements, evaluate a Tcl
script consisting of command with the
two elements appended as additional
arguments. The script should return an
integer less than, equal to, or greater
than zero if the first element is to be
considered less than, equal to, or
greater than the second, respectively.
- increasing Sort the list in increasing order
(``smallest'' items first). This is the
default.
- decreasing Sort the list in decreasing order
(``largest'' items first).
