awk或者sed如何处理这样的问题

wjw870907

cat file
gidNumber: 820
cn: icac
memberUid: aaa
memberUid: bbb
memberUid: ccc
gidNumber: 821
cn: datax
memberUid: ddd
memberUid: aaa
gidNumber: 822
cn: exchange
这里是3条记录
一个文件里gidNumber和cn 是肯定有的，memberUid可能有多个也可能没有，如何做到
gidNumber: 820,cn: icac,memberUid: aaa|bbb|ccc
gidNumber: 821,cn: datax,memberUid: ddd|aaa
gidNumber: 822,cn: exchange,

有高手吗有高手吗有高手吗

Looiml

sed -nr '1h;1!H;${g;:a;s/(memberUid: )([^\n]+)\n\1/\1\2|/;ta;s/\n(cn|mem)|$/,\1/g;p}' file
gidNumber: 820,cn: icac,memberUid: aaa|bbb|ccc
gidNumber: 821,cn: datax,memberUid: ddd|aaa
gidNumber: 822,cn: exchange,

Looiml

1. awk -F'[: ]+' '/^mem/{printf a?"|"$2:$0;a=1;next}{a=0;if(/^gid/)print "";printf $0","}' file

gidNumber: 820,cn: icac,memberUid: aaa|bbb|ccc
gidNumber: 821,cn: datax,memberUid: ddd|aaa
gidNumber: 822,cn: exchange,

1. cat 1
   
2. gidNumber: 820
   
3. cn: icac
   
4. memberUid: aaa
   
5. memberUid: bbb
   
6. memberUid: ccc
   
7. gidNumber: 821
   
8. cn: datax
   
9. memberUid: ddd
   
10. memberUid: aaa
    
11. gidNumber: 822
    
12. cn: exchange
    
13. 
    
14. awk '/^gidNumber/{if(a){print a;a=b=""};a=$0}/^cn/{a=a","$0","}/^memberUid/{a=b?a"|"$2:a""$0;b++}END{if(a){print a}}' 1
    
15. awk '/^gidNumber/{a[++b]=$0;c=""}/^cn/{a[b]=a[b]","$0","}/^memberUid/{a[b]=c?a[b]"|"$2:a[b]""$0;c++}END{for(i=1;i<=length(a);i++){print a[i]}}' 1
    
16. 
    
17. # 输出。
    
18. gidNumber: 820,cn: icac,memberUid: aaa|bbb|ccc
    
19. gidNumber: 821,cn: datax,memberUid: ddd|aaa
