【转】Linux下patch打补丁命令

转自:http://www.cnblogs.com/noaming1900/archive/2010/10/28/1863282.html

此命令用于为特定软件包打补丁,他使用diff命令对源文件进行操作。
基本命令语法:
patch [-R] {-p(n)} [--dry-run] < patch_file_name
p:为path的缩写。
n:指将patch文件中的path第n条’/’及其左边部分取消。
-R:卸载patch包。
--dry-run:尝试patch软件,并不真正修改软件。
使用实例:
/home/sense/patch-2.6.19.1

=============================================================

此patch文件的path=a/arch/i386/kernel/acpi

[sense@ssn src]$ pwd
/usr/src
[sense@ssn src]$ tree
.
`-- a
`-- arch
       `-- i386
         `-- kernel
            `-- acpi

 和a/同目录时:

[sense@ssn src]$ pwd
/usr/src
[sense@ssn src]$ patch -p0 < /home/sense/patch-2.6.19.1   安装补丁
[sense@ssn src]$ patch -p0 -R < /home/sense/patch-2.6.19.1   卸载补丁
和a/arch/同目录时:
[sense@ssn src]$ pwd
/usr/src/a/
[sense@ssn src]$ patch -p1 < /home/sense/patch-2.6.19.1   安装补丁
[sense@ssn src]$ patch -p1 -R < /home/sense/patch-2.6.19.1   卸载补丁
和a/arch/i386/同目录时:
[sense@ssn src]$ pwd
/usr/src/a/arch/
[sense@ssn src]$ patch -p2 < /home/sense/patch-2.6.19.1   安装补丁
[sense@ssn src]$ patch -p2 -R < /home/sense/patch-2.6.19.1   卸载补丁
