Why do special characters appear in a text file after it is archived with tar gzip?

Question

linux

Hello! I create an archive of a text file with the command:
tar -zcvf file.gz file.txt
But after I unzip it, special characters like: appear at the beginning and end of the source file:

00\00\000000644\000000766\000000766\0000000136472\0012625622023\00015132\00 0\00\00\00\

Is it possible to somehow delete them when unzipping or initially archive the file so that these characters do not appear?

Answer 1

Do not archive it, but compress it. Compression utilities are used for this: gzip, bzip2, etc.

Answer 2

How do you unpack it?
It looks like you're using tar -czf a bit wrong, it produces a gz-compressed tar file, i.e. you get .tgz (or .tar.gz, which is the same). Accordingly, you also need to unpack it either immediately through tar -xzf or first through gunzip then through tar -xf

Answer 3

at the beginning and end of the source file appear special characters like:

Nothing appears anywhere:

$ tar -zcvf file.tgz file.txt
$ tar -zxvf file.tgz

tar - turns the file structure into a "magnetic tape format", tar itself has nothing to do with archiving at all.
If you only need to archive 1 file - don't use tar at all.
