Password-Protected Compressed Files Cause Script to Hang

[deere-eh]

When the script encounters a password-protected compressed file (ZIP), it hangs upon waiting for user input and outputs the password prompt to stderr. Expected behavior would be to skip the password-protected file and issue a warning to stdout and/or stderr.

Example (stderr):

error: -fn or any combination of -c, -l, -p, -t, -u and -v options invalid
unzip: cannot find or open /hadoop-yar, /hadoop-yar.zip or /hadoop-yar.ZIP.
unzip: cannot find or open /hadoop-yar, /hadoop-yar.zip or /hadoop-yar.ZIP.
Enter password:

The final line is the only indication that a password protected file was encountered and there are no further logs beyond it after the script hangs.
