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@ tmp]# touch test1.txt
[root@ tmp]# vim test1.txt
[root@ tmp]# cat test1.txt
cat cat cat
i like linux
i like windows too
i like watching TV
I like chenqingling [root@ tmp]# cp test1.txt text2.txt
[root@ tmp]# cp test1.txt text3.txt
[root@ tmp]# cp test1.txt text4.txt
[root@ tmp]# perl -p -i -e "s/cat/dog/g" test1.txt text2.txt
[root@ tmp]# cat test1.txt
dog dog dog
i like linux
i like windows too
i like watching TV
I like chenqingling [root@ tmp]# cat text2.txt
dog dog dog
i like linux
i like windows too
i like watching TV
I like chenqingling [root@ 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@ tmp]# sed -i "s/linux/Unix/g" text2.txt text3.txt
[root@ tmp]# cat text2.txt
dog dog dog
i like Unix
i like windows too
i like watching TV
I like chenqingling [root@ tmp]# cat text3.txt
cat cat cat
i like Unix
i like windows too
i like watching TV
I like chenqingling [root@ 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@ lu]# sed -i "s/TV/xiaozhan/g" `grep TV -rl ./` #注意这里的`` 不是单引号!!
[root@ lu]# cat text2.txt
dog dog dog
i like Unix
i like windows too
i like watching xiaozhan
I like chenqingling [root@ lu]# cat text3.txt
cat cat cat
i like Unix
i like windows too
i like watching xiaozhan
I like chenqingling [root@ lu]# cat text4.txt
cat cat cat
i like linux
i like windows too
i like watching xiaozhan
I like chenqingling
