- .SH NAME
- lsort \- Sort the elements of a list
- .SH SYNOPSIS
- \fBlsort \fR?\fIswitches\fR? \fIlist\fR
- .BE
-
- .SH DESCRIPTION
- .PP
- This command sorts the elements of \fIlist\fR, returning a new
- list in sorted order. By default ASCII sorting is used with
- the result returned in increasing order.
- .VS
- However, any of the
- following switches may be specified before \fIlist\fR to
- control the sorting process (unique abbreviations are accepted):
- .TP 20
- \fB\-ascii\fR
- Use string comparison with ASCII collation order. This is
- the default.
- .TP 20
- \fB\-integer\fR
- Convert list elements to integers and use integer comparison.
- .TP 20
- \fB\-real\fR
- Convert list elements to floating-point values and use floating
- comparison.
- .TP 20
- \fB\-command\0\fIcommand\fR
- Use \fIcommand\fR as a comparison command.
- To compare two elements, evaluate a Tcl script consisting of
- \fIcommand\fR 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.
- .TP 20
- \fB\-increasing\fR
- Sort the list in increasing order (``smallest'' items first).
- This is the default.
- .TP 20
- \fB\-decreasing\fR
- Sort the list in decreasing order (``largest'' items first).
- .VE

- .SH KEYWORDS
