I need to create a shell script wherein I will unzip a password protected zip file. I know the password, and need to automate the unzip process.

How can I achieve this using Unix shell scripting?

unzip -P your-password zipfile.zip

man unzip

-P password

use password to decrypt encrypted zipfile entries (if any). THIS IS INSECURE! Many multi-user operating systems provide ways for any user to see the current command line of any other user; even on stand-alone systems there is always the threat of over-the-shoulder peeking. Storing the plaintext password as part of a command line in an automated script is even worse. Whenever possible, use the non-echoing, interactive prompt to enter passwords. (And where security is truly important, use strong encryption such as Pretty Good Privacy instead of the relatively weak encryption provided by standard zipfile utilities.)
