This is how dmenu works, it reads data from stdin, and then asks the user do make a choice about them. This isn't a question of calling dmenu twice, this is about you calling dmenu without input in: dmenu -p "nombre de lignes". So dmenu waits for its input from stdin, you close that with ^D, that's expected behaviour. I suppose you were intending something like NbLignes=$(dmenu -p "nombre de lignes" < /dev/null) instead
