Linux, how using tee in piped command

Question

time curl http://www.google.com | tee | wc | gzip > google.gz

Why doesn't this command work? It creates the file, and times the operation, but does not print the number of lines, words, and characters (wc).

time curl http://www.google.com | tee | wc 

This will print print the words characters and lines, but obviously, the tee portion is pointless.

Is it because I'm sending the word count of the url to google.gz?

I have to use tee, gzip, time, curl to download google web page to a gziped file, print the word count, how long it took.

It is an assignment, so I'm not looking for someone to do it for me. I just am having a problem in that I can't tee to utility, and I cant to and gzip at the same time.

Maybe there is a way to use gzip with curl?

Answer 1

Well, wc outputs the number of characters, words and lines, but then you send it to gzip which compresses it. Eventually, compressed information ends up in google.gz . If you decompress the file, eg with

gunzip google.gz

you'll see the three numbers.

Also, normally when one uses tee , they specify a file where the tee'ed data is supposed to be stored.

Answer 2

time curl http://www.google.com | tee /dev/tty | gzip > google.gz

Answer 3

我将猜测您想要的是这样的东西：

time curl http://www.google.com | tee /tmp/z | gzip > google.gz; wc /tmp/z; rm /tmp/z
