# gzip/unzip
|
||
```shell
|
||
Usage: gzip [OPTION]... [FILE]...
|
||
Compress or uncompress FILEs (by default, compress FILES in-place).
|
||
|
||
Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]
|
||
Default action is to extract files in list, except those in xlist, to exdir;
|
||
file[.zip] may be a wildcard. -Z => ZipInfo mode ("unzip -Z" for usage).
|
||
```
|
||
|

**常用案例**
|
||
```shell
|
||
# 压缩后保留原文件
|
||
gzip -k <filename>
|
||
# 递归压缩目录内所有文件
|
||
gzip -r <dir>
|
||
# 压缩级别设置: -1（最快）到 -9（最高压缩比），默认 -6
|
||
gzip -k -1 <filename>
|
||
# 流式压缩（处理大文件）：边读边压缩
|
||
cat <filename> | gzip > <filename>.gz
|
||
|
||
# 解压到指定目录
|
||
unzip file.zip -d /target/path
|
||
# 列出压缩包内容
