Simple disk operations

A simple operation of the disk
1, disk space Check
DF -H
-H: Human Abbreviation, displays the results to a more readable manner (i.e. with units: for example, M / G, if not this parameter, in the digital display units B )
2, view the current directory of the size of the space occupied
du -SH
-s: recursion whole entire directory size; -h: user-friendly display

Second, conventional packing compression, decompression
tar
　　unpack: tar xvf fileName.tar
　　Packing: tar CVF filename.tar DirName
　　(Note:! tar is packaged, not compressed)
GZ
　　decompression 1: gunzip filename.gz
　　extracting 2: gzip -d fileName.gz
　　compression: the gzip FileName
the tar.gz tgz and
　　decompression: tar zxvf fileName.tar.gz
　　compression: the tar zcvf filename.tar.gz DirName
ZIP
　　decompression: unzip fileName.zip
　　compression: zip fileName.zip DirName
　　Compress a directory using -r parameter, -r recursively. Example: $ -R & lt filename.zip DirName ZIP
RAR
　　decompression: rar x FileName.rar
　　compression: rar a FileName.rar DirName
