$ curl -s http://www.script-o-rama.com/movie_scripts/a1/bee-movie-script-transcript-seinfeld.html -O
Os itens acima resultarão no download desse arquivo - bee-movie-script-transcript-seinfeld.html
.
replicar arquivo para 100 cópias
$ for i in {001..100}; do \
cp bee-movie-script-transcript-seinfeld.html jacob${i}.txt; done
Resultando nestes arquivos:
$ ls
