To view the first member of an archive, use the funzip command with the file name.
funzip archive.zip
Similarly, for .gz file, use the following command −
funzip archive.gz
2. Viewing the Contents of the First Member of an Archive with Multiple Members
An archive file can have multiple files. To list the contents of a zip archive, use the command given below −
unzip -l archive.zip

If the archive file is password-protected, the password can be specified with the dash (-). However, it is not a secure way to access the archive.
funzip -abc123 archive.zip
In the above command, abc123 is the password.
4. Viewing the Contents of the First Member of an Archive by Piping the Output
The funzip command output can be piped to the more and less commands. These commands are used to display large output with easier navigation. The more command presents the output one screen at a time, while the less command is easier to navigate with directional keys.
funzip archive.zip | more
The output of the less command can be obtained using the command given below −
funzip archive.zip | less
5. Saving the Contents of the First Member of an Archive
To save the contents of the first member of an archive file, use the redirection operator (>).
funzip archive.zip > file
The archive has more than one file. The warning will be shown to the standard output while the content will be saved in the file as shown in the output image.
