[Batch] number of lines in a file

bonjour
change this line

if %compt% LEQ 0 GOTO :end

Thank you very much for your help, Dubcek.
You want to check if my variable is less than or equal to 0, and go to :end

But if I want to go to the :yes function if that number is greater than or equal to 1
should I use GEQ?

if %compt% GEQ 0 GOTO :oui goto :end :oui echo ouii > C:\wamp\www\batch\oui.txt :end

Thank you very much, it works.
I have a file that contains the absolute path of a file (chemin.txt).

C:\truc\truc\truc\truc\truc\truc\Aaaa.html.htm

I would like to extract just the name of my file and put it in a variable.
I used an awk command that extracts this name and puts it into a file (fichier.txt)

Here it is and it works:

awk -F""\\"" "{print $8}" C:\wamp\www\batch\chemin.txt > C:\wamp\www\batch\fichier.txt

Now when I want to retrieve the content of this file and put it in a variable, it doesn't work. Could you help me with that please?
I did it like this:

set /p file= <C:\wamp\www\batch\fichier.txt echo %file% > C:\wamp\www\batch\verifier.txt

When I open verifier.txt, I find ECHO command is enabled.
Thank you very much.
