由于目前测试的BIOS有一个option 发生了改变，因此我们需要在之前写好的脚本上进行修改，将旧的option 改为新的选项，因此在此处用到了批量修改文件中的内容；

1. perl 命令替换：

perl -i -e "s/old/new/g" the path of the file

下面，就将test1 text2，中的cat 都换成了dog，汪汪~~

[root@11 tmp]# touch test1.txt [root@11 tmp]# vim test1.txt [root@11 tmp]# cat test1.txt cat cat cat i like linux i like windows too i like watching TV I like chenqingling [root@11 tmp]# cp test1.txt text2.txt [root@11 tmp]# cp test1.txt text3.txt [root@11 tmp]# cp test1.txt text4.txt [root@11 tmp]# perl -p -i -e "s/cat/dog/g" test1.txt text2.txt [root@11 tmp]# cat test1.txt dog dog dog i like linux i like windows too i like watching TV I like chenqingling [root@11 tmp]# cat text2.txt dog dog dog i like linux i like windows too i like watching TV I like chenqingling [root@11 tmp]# cat text3.txt cat cat cat i like linux i like windows too i like watching TV I like chenqingling

2.运用sed 命令批量修改文件内容：

sed -i "s/old/new/g" the path of the files

修改text2，text3，中的linux ,修改为Unix

[root@11 tmp]# sed -i "s/linux/Unix/g" text2.txt text3.txt [root@11 tmp]# cat text2.txt dog dog dog i like Unix i like windows too i like watching TV I like chenqingling [root@11 tmp]# cat text3.txt cat cat cat i like Unix i like windows too i like watching TV I like chenqingling [root@11 tmp]# cat test1.txt dog dog dog i like linux i like windows too i like watching TV I like chenqingling

3.补充点：将old 全部换成 new

sed -i “s/old/new/g” `grep old -rl /path` #当前路径表示：./

[root@110 lu]# sed -i "s/TV/xiaozhan/g" `grep TV -rl ./` #注意这里的`` 不是单引号！！ [root@11 lu]# cat text2.txt dog dog dog i like Unix i like windows too i like watching xiaozhan I like chenqingling [root@11 lu]# cat text3.txt cat cat cat i like Unix i like windows too i like watching xiaozhan I like chenqingling [root@11 lu]# cat text4.txt cat cat cat i like linux i like windows too i like watching xiaozhan I like chenqingling
