examples

Packaging files into tarballs:

tar -cvf log.tar log2012.log

Package only, no compression!

tar -zcvf log.tar.gz log2012.log

After packaging, compress it with gzip

tar -jcvf log.tar.bz2 log2012.log

After packaging, compress it with bzip2

Within folders, files newer than a certain date are backed up:

tar -N "2018/3/1" -zcvf log.tar.gz test

The simplest way to use tar is to remember the following three ways:

tar -jcv -f filename.tar.bz2

File or directory name query to compress:

tar -jtv -f filename.tar.bz2

Decompression:

tar -jxv -f filename.tar.bz2 -C

Contents to be decompressed
