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).
