grammar 

gzip [-acdfhlLnNqrtvV][-S <压缩字尾字符串>][-<压缩效率>][--best/fast][文件...] 或 gzip [-acdfhlLnNqrtvV][-S <压缩字尾字符串>][-<压缩效率>][--best/fast][目录]

Parameters:

  • -a or --ascii using ASCII text mode.
  • -c or --to-stdout --stdout or the compressed file to the standard output device, not to the original file changes.
  • -d or --decompress ---- uncompress or extract the zipped files.

Examples

Compressed file 

[[email protected] a]# ls //显示当前目录文件
a.c b.h d.cpp
[[email protected] a]# gzip * //压缩目录下的所有文件
[[email protected] a]# ls //显示当前目录文件
a.c.gz	b.h.gz	d.cpp.gz
[[email protected] a]#

Example 1 pick lists details 

[[email protected] a]# gzip -dv * //解压文件，并列出详细信息
a.c.gz:	 0.0% -- replaced with a.c
b.h.gz:	 0.0% -- replaced with b.h
d.cpp.gz:	 0.0% -- replaced with d.cpp
[[email protected] a]#

Then Example 1, a compressed file information 

[[email protected] a]# gzip -l *
     compressed    uncompressed ratio uncompressed_name
         24          0  0.0% a.c
         24          0  0.0% b.h
         26          0  0.0% d.cpp
