Параметры (Options)
The lex utility shall conform to the Base Definitions volume of
POSIX.1‐2017, Section 12.2, Utility Syntax Guidelines, except for
Guideline 9.
The following options shall be supported:
-n Suppress the summary of statistics usually written with
the -v option. If no table sizes are specified in the
lex source code and the -v option is not specified,
then -n is implied.
-t Write the resulting program to standard output instead
of lex.yy.c.
-v Write a summary of lex statistics to the standard
output. (See the discussion of lex table sizes in
Definitions in lex.) If the -t option is specified and
-n is not specified, this report shall be written to
standard error. If table sizes are specified in the lex
source code, and if the -n option is not specified, the
-v option may be enabled.
