I just use gunzip as tool for unzip an .zip file at ubuntu 10.04 when I try same utility at freebsd.
Now I want to try something new with utility called unzip.
Try to call it ( it might be installed)
unzip: Command not found.
Not found, try to find installation file.
# whereis unzip
# cdÂ /usr/ports/archivers/unzip && make install
