Let’s create and encrypt an archive file encrypted-backup.zip: $ zip -e encrypted-backup.zip bank-accounts.txt credentials.txt Nevertheless, it creates and puts the bank-accounts.txt and customer-details.txt into the archive. We can see that the zip command prints a warning, telling us the archive total-new-archive.zip is not found. Zip warning: total-new-archive.zip not found or empty Let’s run the zip -g command with a non-existent archive filename: $ zip -g total-new-archive.zip bank-accounts.txt customer-details.txt If the specified archive file doesn’t already exist, the zip command will create it. rw-r-r- 3.0 unx 16 tx stor 21-May-03 11:49 customer-details.txtģ files, 41 bytes uncompressed, 41 bytes compressed: 0.0% Zip file size: 551 bytes, number of entries: 3 Now, the archive will consist of three entries in total: $ zipinfo important-backup.zip In the example above, we’re adding the new entries bank-accounts.txt and customer-details.txt into the important-backup.zip. We can add two more entries into the important-backup.zip archive by passing the flag -g to the zip command: $ zip -g important-backup.zip bank-accounts.txt customer-details.txt Zip file size: 188 bytes, number of entries: 1 The zip command provides the option to append additional entries to an existing archive using the -g flag.įor example, let’s say we have an existing archive, important-backup.zip: $ zipinfo important-backup.zip
