File inc.l:

%%
[0-9]+ printf("%d",atoi(yytext)+1);

Compile:

$ flex inc.l
$ gcc lex.yy.c -o inc -lfl

Run:

$ echo 'teststring134this 123test string54 100' | ./inc
teststring135this 124test string55 101
$ i='(-: 2 empty bottles of beer :-)'
$ tty=$(tty)
$ for n in {2..5} ; do i=$(./inc<<<$i|tee $tty) ; done
(-: 3 empty bottles of beer :-)
(-: 4 empty bottles of beer :-)
(-: 5 empty bottles of beer :-)
(-: 6 empty bottles of beer :-)

I did not test this with the original lex. Comments are welcome.
