Tcl Built-In Commands


lsort - Sort the elements of a list


lsort ?switches? list


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):

Use string comparison with ASCII collation order. This is the default.

Convert list elements to integers and use integer comparison.

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.

Sort the list in increasing order (``smallest'' items first). This is the default.

Sort the list in decreasing order (``largest'' items first).
