How do I unzip a PASSWORD PROTECTED .gz file using SAS code?

Bruno7 — Mon, 02 May 2022 14:24:13 GMT

I know there is a way to unzip .gz files with SAS code, but is there a way to also open password protected .gz files using SAS code?

Example:

x gunzip --stdout "/mydir/test_gz_password_protected.sas7bdat.gz" > "/mydir/test_gz_no_password.sas7bdat";

How do I modify this to incorporate the password?

From what I've read gzip does not support password encryption. The techniques people use involve another tool to encrypt the content and then pipe it to gzip.

If that's the case, then expanding it to an unencrypted version would involve the reverse process. Unzip the gz, and pipe the content to the tool to decrypt. Without knowing how the original was encrypted we cannot offer a specific command syntax.

The FILENAME ZIP / GZIP method can't be used for this, at least not on its own.
