Summary

The unzip utility is used to list, test, or extract files from a zip

archive. Zip archives are commonly found on MS-DOS systems. The zip

utility, included in the zip package, creates zip archives. Zip and

unzip are both compatible with archives created by PKWARE(R)'s PKZIP

for MS-DOS, but the programs' options and default behaviors do differ

in some respects.

Install the unzip package if you need to list, test or extract files from

a zip archive.
