1. #!/bin/bash
   
2. while read line
   
3. do
   
4.         echo `echo $line|tr  "[ #{}]"  "\n"|awk 'BEGIN{RS="[\n]+";ORS=" "}{print $0}'`
   
5. done

cat x.txt
1. {#a#a#}

fdss{#sd#jas#}fdjsf{#ds#fjs#}dfs
fdss{#sd#jas#}fdjsf{#ds#fjs#}dfs

运行：bash x.sh < x.txt
1. a a
2. a a
3. a a

fdss sdjas fdjsf dsfjs dfs

个人理解这位坛友，是想把文档处理的规整化，至少可以被AWK 规范化处理：

稍微修改下 就是+号链接版本的输出：如下

1. #!/bin/bash
   
2. while read line
   
3. do
   
4.         echo `echo $line|tr  "[ #{}]"  "\n"|awk 'BEGIN{RS="[\n]+";ORS="+"}{print $0}'|sed 's/+$/\n/'`
   
5. done

cat x.txt

2. {#a}a#}
3. {#a#}a#}
