To view the contents of a .gz compressed text file on the screen in Unix or Linux, you can use the cat command in combination with the gunzip command.
For example, to view the contents of the file text.txt.gz, you can use the following command:
gunzip -c text.txt.gz | cat
This will uncompress the contents of text.txt.gz using gunzip and pipe the output to the cat command, which will display the contents of the file on the screen.
You can also use the zcat command to view the contents of a .gz compressed text file on the screen. This command is equivalent to gunzip -c.
For example:
zcat text.txt.gz
This will display the contents of text.txt.gz on the screen.
Keep in mind that the cat and zcat commands will not modify the original .gz file. If you want to uncompress the file and save the uncompressed version, you can use the gunzip command without the -c option.
For example:
gunzip text.txt.gz
This will uncompress text.txt.gz and save the uncompressed version as text.txt. The original .gz file will not be modified.
