sed脚本

将单引号中的定址和命令写在脚本中

[root@shell shelldoc]#  cat sc1.sed
/Lewis/a \
i am lewis \
who are you
/Suan/c has suan
1i \
************\
begin\
************
$d
[root@shell shelldoc]# sed -f sc1.sed datafile  //执行脚本
************
begin
************

​ 带幻数的脚本

[root@shell shelldoc]#  sc1.sed
#!/bin/sed -f
/Lewis/a \
i am lewis \
who are you
/Suan/c has suan
1i \
************ \
begin \
************
$d
[root@shell shelldoc]# chmod +x sc1.sed
[root@shell shelldoc]# ./sc1.sed datafile

假设脚本中使用了扩展正则，那么选项还得加-r
sed -rf sc2.sed filename
#!/bin/sed -rf
