The basic format of the gzip command is as follows:
[root@localhost ~]# gzip [选项] 源文件
Basic compression
The gzip compression command is very simple. You don't even need to specify the compressed package name after compression, just the source file name. Let’s try:
[root@localhost ~]# gzip install.log #压缩instal.log 文件 [root@localhost ~]# ls anaconda-ks.cfg install.log.gz install.log.syslog #压缩文件生成,但是源文件也消失了
Preserve source file compression
When compressing a file using the gzip command, the source file disappears, resulting in a compressed file. At this time, some people will have obsessive-compulsive disorder and ask the author: Can you prevent the source file from disappearing when compressing the file? Okay, it's possible, but it's very awkward.
[root@localhost ~]# gzip -c anaconda-ks.cfg >anaconda-ks.cfg.gz #使用-c选项,但是不让压缩数据输出到屏幕上,而是重定向到压缩文件中,这样可以缩文件的同时不删除源文件 [root@localhost ~]# ls anaconda-ks.cfg anaconda-ks.cfg.gz install.log.gz install.log.syslog #可以看到压缩文件和源文件都存在
