lsort
Sort the elements of a list
Syntax
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
control the sorting process (unique abbreviations are accepted):
- -ascii
- Use string comparison with ASCII collation 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).
