Gzip 缩写为GUN zip，它是Linux中经常使用的命令之一。

gzip 命令用于压缩文件以减少文件的大小。

如果文件在不同的系统之间传输，这将节省带宽。此外，减少的大小取决于文件的内容，如果内容是文本，它将减少60%，对于图像，它应该是80%。

如果我们想复制多个文件，文件应该被压缩，这样文件的带宽就会减少。

Gzip命令的例子

让我们看看gzip命令的不同例子

如何在压缩文件的同时删除原始文件

这将用 linuxFileName.gz 替换一个 linuxFileName，该文件在当前目录中的大小减少到 80%。通过这个命令，文件名的大小被减少了。一旦gz文件被创建，linuxFileName应该被删除。

压缩文件并保留原始文件

这个命令的行为和上面的命令一样，希望原始文件不被删除。所以原始文件应该保持原样。你将在当前目录下有两个文件linuxFileName和linuxFileName.gz。

解压缩/解压gz文件

这将在使用gzip命令之前解压filename.gz并获得原始文件。

压缩一个目录中的多个文件

Gzip -r directoryname
```using -r option, recursively traverse all the files, meaning all the files in the current directory including all the files subdirectory and create a directoryname.gz which contains all the files in the current directory and subdirectory
After compression, the total size of the files is approximately 20% less gz file.
## Uncompress/decompress the gz file into multiple files
Gunzip -r fileName.gz
## Compression files fastly
Gzip -1 filename.txt Gzip -fast filename.txt
Gzip -9 filename.txt Gzip -best filename.txt
The both above options compress filename.txt files slowly and create filename.txt.gz folder
**Advanced gzip examples**
## zip each file in the current directory and creating separate gz
for filename in *.txt; do gzip -c "$filename" > "$
let us say we have file1.txt,file2.txt,file3.txt in the current directory /tmp/directory. To do this, we have to iterate each file and do the gzip command redirect(>) the output as gz file
The above command create file1.txt.gz,file2.txt.gz,file3.txt.gz
\-c option keep all the original files (file1.txt,file2.txt,file3.txt) and give the file to stdout console.
if we don't specified any option, it will remove all the files, and create a gz file
Hope you got basic start for gzip with examples.
