请帮写个shell脚本

cxfcxf

development:~# cat asd.txt
/*xxxxxxxxxxxxxxxxxxxxx
/*xxxxxxxx/*xxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxx*/
development:~# sed -e 's/\/\*/\ \*/g' -e '1s/^\ \*/\/\*/' asd.txt
/*xxxxxxxxxxxxxxxxxxxxx
*xxxxxxxx *xxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxx*/

这样总万能了吧..

lucash

aaaaaaaaaa
/*xxxxxxxxxxxxxxxxxxxxx
/*xxxxxxx/*xxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxx*/
aaaaaaaaaaa
aaaaaaaaaaa
/*adDDDDDDDDDDddddddd
*dddddddddddddddddd
ddddddddddddddddddd*/

这样还能吗？

lucash

sed ':a;N;s/\/\*/\*/2;ta' file

cxfcxf

sed写不来 就用perl凑活了
这个总万能了吧

development:~# cat asd.txt
aaaaaaaaa
/*xxxxxxxxxxxxxxxxxxxxx
/*xxxxxxx/*xxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxx*/
aaaaaaaaaaa
aaaaaaaaaaa
/*adDDDDDDDDDDddddddd
*dddddddddddddddddd
ddddddddddddddddddd*/

1. 
   
2. development:~# cat cclear.pl
   
3. #!/usr/bin/perl
   
4. 
   
5. use strict;
   
6. use warnings;
   
7. 
   
8. $/ = "";
   
9. foreach (<>) {
   
10.     chomp;
    
11.     s/\/\*/\ \*/g;
    
12.     s/\ \*([^\ \*]*)/\/\*$1/;
    
13.     print "$_\n";
    
14. }
    

复制代码

development:~# ./cclear.pl asd.txt
aaaaaaaaa
/*xxxxxxxxxxxxxxxxxxxxx
*xxxxxxx *xxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxx*/
aaaaaaaaaaa
aaaaaaaaaaa
*adDDDDDDDDDDddddddd
*dddddddddddddddddd
ddddddddddddddddddd*/

还是别样子?
要/* */之间的 换个换行符就可以了

1. 
   
2. #!/usr/bin/perl
   
3. 
   
4. use strict;
   
5. use warnings;
   
6. 
   
7. $/ = '*/';
   
8. foreach (<>) {
   
9.     s/\/\*/\ \*/g;
   
10.     s/\ \*([^\ \*]*)/\/\*$1/;
    
11.     print "$_";
    
12. }
    

复制代码

development:~# ./cclear.pl asd.txt
aaaaaaaaa
/*xxxxxxxxxxxxxxxxxxxxx
*xxxxxxx *xxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxx*/
aaaaaaaaaaa
aaaaaaaaaaa
/*adDDDDDDDDDDddddddd
*dddddddddddddddddd
ddddddddddddddddddd*/

你自己这个没试过吧?
development:~# cat asd.txt
aaaaaaaaa
/*xxxxxxxxxxxxxxxxxxxxx
/*xxxxxxx/*xxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxx*/
aaaaaaaaaaa
aaaaaaaaaaa
/*adDDDDDDDDDDddddddd
*dddddddddddddddddd
ddddddddddddddddddd*/
development:~# sed ':a;N;s/\/\*/\*/2;ta' asd.txt
aaaaaaaaa
/*xxxxxxxxxxxxxxxxxxxxx
/*xxxxxxx*xxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxx*/
aaaaaaaaaaa
aaaaaaaaaaa
/*adDDDDDDDDDDddddddd
*dddddddddddddddddd
ddddddddddddddddddd*/

明显不对啊

richiewu

看来只能动用脚本了,一点点语句搞不定...

famdestiny

感谢两位达人啊

cxfcxf

可以搞定啊 用sed 吧换行符设成*/ 然后笨的就2句 一句是 s/\/\*/\ \*/g;  一句是 s/\ \*([^\ \*]*)/\/\*$1/; 这里sed写法不一样 $1 是\1  而括号要\(  \)
聪明的肯定有.....大牛写的出..我写不出...
sed太差...惭愧

果然有问题。。多谢指出

lucash

改正一下：

sed '/^\/\*/,/\*\/$/{:a;N;s/\(\/\*\)\([^/\]*\)\/\*/\1\2\*/;ta}' file
