'''ftruncate''' is a command in [TclX]:

From the man pages:


    :   '''ftruncate''' [['''-fileid''']] ''file newsize''
Truncate ''file'' to have a length of at most ''newsize'' bytes.

If the option '''-fileid''' is specified, ''file'' is an open file identifier, otherwise it is a file path.

This command is not available or not fully functional if the underlying operating system support is not available.

The command '''[infox] have_truncate''' will indicate if this command may truncate by file path.
The command '''[infox] have_ftruncate''' will indicate if this command may truncate by file id.

The '''-fileid''' option is not available on Windows 95/NT.
