Tar-A folder where files are packaged and compressed after being packaged and compressed by czvf

[root@ied01 demo] # tar-czvf myetc.tar.gz etc if the package is compressed into .bz2 format, then the argument to the tar command is-cjvf.

Case 2: first delete the etc directory and extract the myetc.tar.gz to the current directory.

1) delete the etc directory

[root@ied01 demo] # rm-rf etc2) extract the myetc.tar.gz to the current directory

[root@ied01 demo] # tar-xzvf myetc.tar.gz
