将 sed -e 命令组合起来创建单个 sed 脚本.以下产生相同的结果(注意 -e 是隐含的):

The sed -e commands are combined to create a single sed script. The following yields the same results (notice that -e is implied):

sed '
    s/1/ONE/
    s/2/TWO/
    /3/q
    s/ONE/THREE/
' input.txt

或者作为单衬:

sed 's/1/ONE/; s/2/TWO/; /3/q; s/ONE/THREE/' input.txt
