[linux] Compress files while reading data from STDIN

Is it possible to compress (create a compressed archive) data while reading from stdin on Linux?

Yes, gzip will let you do this. If you simply run gzip > foo.gz, it will compress STDIN to the file foo.gz. You can also pipe data into it, like some_command | gzip > foo.gz.

gzip > stdin.gz perhaps? Otherwise, you need to flesh out your question.
