lex – generator of lexical analysis programs|
lex [ –tvn9 ] [ file ... ]|
Lex generates programs to be used in simple lexical analysis of
text. The input files (standard input default) contain regular
expressions to be searched for and actions written in C to be
executed when expressions are found. |
A C source program, lex.yy.c is generated. This program, when run, copies unrecognized portions of the input to the output, and executes the associated C action for each regular expression that is recognized.
The options have the following meanings.
This program converts upper case to lower, removes blanks at the
end of lines, and replaces multiple blanks by single blanks.
