You have this tagged with both zip and gzip, but here's both. These are both pretty standard Unix tools, whic Mac OS X supports (as far as I know, anyway):

zip file: unzip -vl file.zip

Example:

[23:02:22] ~/Download $ unzip -vl lightbox2.04.zip 
Archive:  lightbox2.04.zip
 Length   Method    Size  Cmpr    Date    Time   CRC-32   Name

[23:02:36] ~/Download $ 

gzip file: gunzip -lv file.gz

Example:

[23:03:55] ~/Download $ gunzip -lv mudlet.tar.gz

On Max OS X and Linux, you can use zipinfo:

zipinfo -m my_file.zip > list_my_file.txt

Output (more list_my_file.txt):

Archive:  my_file.zip
Zip file size: 3220317423 bytes, number of entries: 1998436
drwxrwxr-x  3.0 unx        0 bx  0% stor 15-Nov-26 07:14 p/
-rw-rw-r--  3.0 unx     4666 tx 77% defN 15-Nov-23 23:31 p/r2082514.json

-rw-rw-r--  3.0 unx     6979 tx 78% defN 15-Nov-22 19:40 p/r1675696.json
-rw-rw-r--  3.0 unx     5460 tx 78% defN 15-Nov-22 23:11 p/r1761107.json
-rw-rw-r--  3.0 unx     4960 tx 74% defN 15-Nov-23 00:58 p/r1801562.json
-rw-rw-r--  3.0 unx     6459 tx 75% defN 15-Nov-21 19:00 p/r1261556.json

The flag -m displays the compression ratio:

-m     list zipfile info in medium Unix ``ls -l'' format.  Identical to
              the -s output, except that the compression factor, expressed  as
              a percentage, is also listed.
