I have several directories that look like this:
dir1/ |_foo.txt |_bar.txt dir2/ |_qux.txt |_bar.txt For each of this directory I want to compress the files inside it into *.gz format then delete the uncompressed ones. So finally we hope to get something like this:
dir1/ |_foo.gz |_bar.gz dir2/ |_qux.gz |_bar.gz Is there a simple Unix way to do it?

If you want to compress multiple files or directory into one file, first you need to create a Tar archive and then compress the . tar file with Gzip.
Gzip is not capable of compressing multiple files into one.
The most important difference is that gzip is only capable to compress a single file while zip compresses multiple files one by one and archives them into one single file afterwards. Thus, gzip comes along with tar most of the time (there are other possibilities, though).
gzip */*.txt But the extension for each file will be .txt.gz, as gzip uses it to know the original filename.

gzip -r dir1 dir2
