为了节省一些磁盘空间并将文件打包在一起进行归档,我们中的一些人已经在 Unix 和 Linux 系统上压缩文件数十年了。即使这样,并不是所有人都尝试过一些有趣的压缩工具的变体。因此,在本文中,我们将介绍标准的压缩和解压缩以及其他一些有趣的压缩选项。

### 基本的 zip 命令
|
2019-01-25 17:09:48 +08:00

首先,让我们看一下基本的 `zip` 命令。它使用了与 `gzip` 基本上相同的压缩算法,但是有一些重要的区别。一方面,`gzip` 命令仅用于压缩单个文件,而 `zip` 既可以压缩文件,也可以将多个文件结合在一起成为归档文件。另外,`gzip` 命令是“就地”压缩。换句话说,它会留下一个压缩文件,而不是原始文件。 这是工作中的 `gzip` 示例:
|
2019-01-25 17:09:48 +08:00
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ gzip onefile
|
|
|
|
|
$ ls -l
|
|
|
|
|
-rw-rw-r-- 1 shs shs 10514 Jan 15 13:13 onefile.gz
|
|
|
|
|
```
|
|
|
|
|
|
2020-02-03 23:13:22 +08:00
|
|
|
|
而这是 `zip`。请注意,此命令要求为压缩存档提供名称,其中 `gzip`(执行压缩操作后)仅使用原始文件名并添加 `.gz` 扩展名。
|

|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ zip twofiles.zip file*
|
|
|
|
|
adding: file1 (deflated 82%)
|
|
|
|
|
adding: file2 (deflated 82%)
|
|
|
|
|
$ ls -l
|
|
|
|
|
-rw-rw-r-- 1 shs shs 58021 Jan 15 13:25 file1
|
|
|
|
|
-rw-rw-r-- 1 shs shs 58933 Jan 15 13:34 file2
|
|
|
|
|
-rw-rw-r-- 1 shs shs 21289 Jan 15 13:35 twofiles.zip
|
|
|
|
|
```
|
|
|
|
|
|
2020-02-03 23:13:22 +08:00
|
|
|
|
请注意,原始文件仍位于原处。

所节省的磁盘空间量(即获得的压缩程度)将取决于每个文件的内容。以下示例中的变化很大。
|
2019-01-25 17:09:48 +08:00
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ zip mybin.zip ~/bin/*
|
|
|
|
|
adding: bin/1 (deflated 26%)
|
|
|
|
|
adding: bin/append (deflated 64%)
|
|
|
|
|
adding: bin/BoD_meeting (deflated 18%)
|
|
|
|
|
adding: bin/cpuhog1 (deflated 14%)
|
|
|
|
|
adding: bin/cpuhog2 (stored 0%)
|
|
|
|
|
adding: bin/ff (deflated 32%)
|
|
|
|
|
adding: bin/file.0 (deflated 1%)
|
|
|
|
|
adding: bin/loop (deflated 14%)
|
|
|
|
|
adding: bin/notes (deflated 23%)
|
|
|
|
|
adding: bin/patterns (stored 0%)
|
|
|
|
|
adding: bin/runme (stored 0%)
|
|
|
|
|
adding: bin/tryme (deflated 13%)
|
|
|
|
|
adding: bin/tt (deflated 6%)
|
|
|
|
|
```
|
|

### unzip 命令

2020-02-03 23:13:22 +08:00
|
|
|
|
`unzip` 命令将从一个 zip 文件中恢复内容,并且,如你所料,原来的 zip 文件还保留在那里,而类似的`gunzip` 命令将仅保留未压缩的文件。
|
2019-01-25 17:09:48 +08:00
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ unzip twofiles.zip

### zipcloak 命令

`zipcloak` 命令对一个 zip 文件进行加密,提示你输入两次密码(以确保你不会“胖手指”),然后将该文件原位存储。你可以想到,文件大小与原始文件会有所不同。
|
2019-01-25 17:09:48 +08:00

|
|
|
|
2020-02-03 23:13:22 +08:00
|
|
|
|
请记住,压缩包之外的原始文件仍处于未加密状态。

### zipdetails 命令
|
2019-01-25 17:09:48 +08:00
|
|
|
|
|
2020-02-03 23:13:22 +08:00
|
|
|
|
`zipdetails` 命令将向你显示详细信息:有关压缩文件的详细信息,可能比你想象的要多得多。即使我们正在查看一个加密的文件,`zipdetails` 也会显示文件名以及文件修改日期、用户和组信息、文件长度数据等。请记住,这都是“元数据”。我们看不到文件的内容。

`zipgrep` 命令将使用 `grep` 类的功能来找到压缩文件中的特定内容。如果文件已加密,则需要为要检查的每个文件输入为加密所提供的密码。如果只想检查归档文件中单个文件的内容,请将其名称添加到 `zipgrep` 命令的末尾,如下所示。

`zipinfo` 命令提供有关压缩文件内容的信息,无论是否加密。这包括文件名、大小、日期和权限。

`zipnote` 命令可用于从 zip 归档中提取注释或添加注释。要显示注释,只需在命令前面加上归档名称即可。如果之前未添加任何注释,你将看到类似以下内容:
|
2019-01-25 17:09:48 +08:00
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ zipnote twofiles.zip
|
|
|
|
|
@ file1
|
|
|
|
|
@ (comment above this line)
|
|
|
|
|
@ file2
|
|
|
|
|
@ (comment above this line)
|
|
|
|
|
@ (zip file comment below this line)
|
|
|
|
|
```
|
|
|
|
|
|
2020-02-03 23:13:22 +08:00
|
|
|
|
如果要添加注释,请先将 `zipnote` 命令的输出写入文件:
|
2019-01-25 17:09:48 +08:00
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ zipnote twofiles.zip > comments
|
|
|
|
|
```
|
|
|
|
|
|
2020-02-03 23:13:22 +08:00
|
|
|
|
接下来,编辑你刚刚创建的文件,将注释插入到 `(comment above this line)` 行上方。然后使用像这样的`zipnote` 命令添加注释:
|
2019-01-25 17:09:48 +08:00
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ zipnote -w twofiles.zip < comments
|
|
|
|
|
```
|
|

### zipsplit 命令

当归档文件太大时,可以使用 `zipsplit` 命令将一个 zip 归档文件分解为多个 zip 归档文件,这样你就可以将其中某一个文件放到小型 U 盘中。最简单的方法似乎是为每个部分的压缩文件指定最大大小,此大小必须足够大以容纳最大的包含文件。
|
2019-01-25 17:09:48 +08:00
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ zipsplit -n 12000 twofiles.zip
|
|
|
|
|
2 zip files will be made (100% efficiency)
|
|
|
|
|
creating: twofile1.zip
|
|
|
|
|
creating: twofile2.zip
|
|
|
|
|
$ ls twofile*.zip
|
|
|
|
|
-rw-rw-r-- 1 shs shs 10697 Jan 15 14:52 twofile1.zip
|
|
|
|
|
-rw-rw-r-- 1 shs shs 10702 Jan 15 14:52 twofile2.zip
|
|
|
|
|
-rw-rw-r-- 1 shs shs 21377 Jan 15 14:27 twofiles.zip
|
|
|
|
|
```
|
|
|
|
|
|
2020-02-03 23:13:22 +08:00
|
|
|
|
请注意,提取的文件是如何依次命名为 `twofile1` 和 `twofile2` 的。

`zip` 命令及其一些压缩工具变体,对如何生成和使用压缩文件归档提供了很多控制。
