unzip command not found in AIX

I get this error when I want to extract unzip files

problem:unzip command not found

so you have to install aix unzip rpm

you can download this site:

http://www-03.ibm.com/systems/power/software/aix/linux/toolbox/alpha.html

After you downloaded rpm

su - root

change directory where rpm is  in there

solution:rpm -ivh unzip-5.51-1.aix5.1.ppc.rpm

Then you can unzip .zip files.

good luck:)))
