如何在Linux中将txt转换为.gz / .z

Question

In Linux, how to convert txt to .gz / .z and how to view that converted tar file?

I tried the command below, but it is not working.

tar -cf filename.z filename.txt
tar -cf filebane.gz filename.txt
zcat filename.z/gz

I get "bad command error".

Answer 1

使用gzip ：

gzip filename.txt

Answer 2

.Z is typically from compress . .gz is from gzip . Tar has nothing to do with it. So, something like this would work to convert .gz to .Z

zcat <file.gz> | compress - > <file.Z>

Or to go the other way:

 zcat <file.Z> | gzip > <file.gz>

(zcat should understand the format used by compress)

Nowadays, .Z formatted files are rarely seen. That format has been supplanted by gzip and bzip2.

Answer 3

Do you want to compress or uncompress the files?

To uncompress, do: gunzip filename.gz results to an uncompressed file filename - if the file really IS a gzip compressed file. On most Linuxes, a command file filename.gz will tell what the file is. For .z use the command uncompress

For compressing, you can use gzip filename.txt which results to filename.txt.gz - if you use compress filename.txt you'll get filename.txt.z

Answer 4

The tar command does not compress files, it archives them. You can add an option to GNU tar to filter it through gzip. Use tar czf fimename.tar.gz filename.txt .
