本文介绍了一种使用bash脚本解压并安装Ramdisk文件的方法。通过gunzip和cpio命令组合，可以实现从.gz压缩包中提取文件，并将其安装到指定目录下。此过程包括了克隆原始文件、解压、创建输出目录及清理临时文件等步骤。 
#!/bin/bash

IMG_FILE=$1

CLONE_FILE="clone-"$IMG_FILE
echo "extract $IMG_FILE ..."
GZ_FILE=$CLONE_FILE".gz"

cp $IMG_FILE $CLONE_FILE
mv $CLONE_FILE $GZ_FILE

gunzip $GZ_FILE

OUT_DIR=${IMG_FILE%.*}

echo "mkdir $OUT_DIR ..."


mkdir $OUT_DIR
cd $OUT_DIR
cpio -i -F ../$CLONE_FILE

rm ../$CLONE_FILE

echo "finished."

或者直接：

gunzip -c ../your-ramdisk-file | cpio -i



Linux命令-cpio命令（用来建立、还原备份档的工具程序）
RisunJan的博客

通过上面的示例，可以看出，cpio无法直接读取文件，它需要每个文件或者目录的完整路径名才能识别读取，而find命令的输出刚好做到了这点，因此，cpio命令一般和find命令配合使用。有时可能因为备份的文件过多，一个屏幕无法显示完毕，此时我们利用下面命令，让磁带机的文件信息输出到文件。cpio命令 主要是用来建立或者还原备份档的工具程序，cpio命令可以复制文件到归档包中，或者从归。注意，cpio恢复的路径，如果cpio在打包备份的时候用的是绝对路径，那么在恢复的时候会自动恢复。

cpio 可以从 cpio 或 tar 格式的归档包中存入和读取文件, 归档包是一种包含其他文件和有关信息的文件。 有关信息包括：文件名, 属主, 时标(timestamp), 和访问权限。 归档包可以是磁盘上的 其他文件, 也可以是磁带或管道。 cpio 有三种操作模式: 在copy-out模式中, cpio 把文件复制到归档包中。它从标准输入获得文件名列表 (一行一个)。默认
[每天一个Linux小技巧] cpio 解压到当前目录

使用 cpio 解压文件中要非常注意一点,　就是打包的文件是绝对路径时有可能 会覆盖系统路径的文件,那就非常悲催了,如你的/bin/ls被替换成arm的ls,这个 系统就有的整了. 所以使用cpio时要记得追加下面的选项: --no-absolute-filenames 用于解压文件到当前目录. 例: cpio --no-absolute-filenames -idu

1.1 cpio基本介绍cpio是一个非常古老的归档工具。已逐渐被tar替代，但是有些功能是tar不存在的，所以还是分享下它的用法。cpio - copy files to and from archivescpio用于创建、解压归档文件，也可以对归档文件执行拷入拷出的动作，即向归档文件中追加文件，或从归档文件中提取文件。它也支持tar格式的归档文件，但是对压缩后的tar(如.tar.gz格式)就...
