The znew command is used to reconvert .Z archives to .gz archives compressed by the gzip command. The gzip command is used to compress files in Linux, and it produces a file with a .gz extension. However, there are some files that are compressed using the compress command, which produces a file with a .Z extension. The znew command is used to convert these .Z files to .gz files, which can be easily extracted using the gzip command.
Overview
The syntax for using the znew command is as follows:
znew [options] [file.Z ...]
The znew command takes one or more .Z files as input and converts them to .gz files. The converted files are saved with the same name as the original file, but with a .gz extension.
Examples
Convert a single .Z file to .gz:
znew file.Z
Convert multiple .Z files to .gz:
znew file1.Z file2.Z file3.Z
Options
The following table lists the available options for the znew command:
| Option | Description |
|---|---|
| -h | Display help message and exit |
| -V | Display version information and exit |
Troubleshooting tips
- If you receive an error message stating that the file is not in a recognized format, the file may not be a valid .Z file. Make sure that you are using the correct file extension and that the file was compressed using the compress command.
- If you receive an error message stating that the file already exists, the file may have already been converted to .gz. Check the directory for the converted file with a .gz extension.
Notes
- The
znewcommand is part of the gzip package, so make sure that the gzip package is installed on your system before using theznewcommand. - The
znewcommand can be used in conjunction with other gzip commands, such asgunzipandgzip, to compress and decompress files in Linux.
