The above option is good if you are using the command inside a shell-script for background jobs. However, when you are performing the compression interactively on the command-line, you don’t want the password to be visible in the history. So, use the option –e as shown below to assign the password.


<nowiki># zip -e var-log-protected.zip /var/log/* Enter password:</nowiki>

<nowiki># unzip var-log-protected.zip Archive: var-log-protected.zip</nowiki>


<nowiki>[var-log-protected.zip] </nowiki>var/log/acpid password:
