sed模式匹配问题，请教，多谢谢，非常紧急。

gxlxld

[root@datanode6 IUT]# cat bb
aa,1,2,3,4,5,aaa,,ccc,dd,ee,1,2,3,4,,h
[root@datanode6 IUT]#
把所有字符串上加""双引号，数字不加，两个逗号之间的加""最后形成
"aa",1,2,3,4,5,"aaa","","ccc","dd","ee",1,2,3,4,"","h"

sed 一行最多允许保存9个模式，但我一行多于9个啊，如何解决，提示，可以把1，2，3，4，5看成一个模式，但小弟还是没有实现，请教 了。多谢。

我这里举了一个例子，我的文件是上万行。

try:

1. sed 's/[^0-9]\+/"&"/g;:a;s/,,/,"",/g;ta' file

:b;s/,,/,"",/g;tb;s/[a-zA-Z]\+/"&"/g

yestreenstars

1. awk -F, -vOFS=, '{for(i=0;i++<NF;)if($i!~/^[0-9]+$/)$i="\""$i"\""}1'

复制代码

1. sed -r 's/[^0-9,]+/"&"/g;:1;s/,,/,"",/g;t1'

复制代码

gxlxld

如果是这样的话呢？上面的aa,1,2,3,4,5,aaa,,ccc,dd,ee,1,2,3,4,,h它为aa,1,2,3,4,5,aaa,,,dd,ee,1,2,3,4,,h 存在连续的,,, 这个需要,"","",

LikeLx

1. sed -e 's/[a-z]\+/"&"/g' -e ':1;s/,,/,"",/;t1'

's/[^0-9,]+/"&"/g;:1;s/,,/,"",/g;t1'  可也实现同样的功能~

标签 ：1  t1  是什么意思， 一直没有搞懂，是循环的意思吗？

学习下~

1. [root@localhost awk_and_sed]# sed 's/[^0-9|^,]\+/"&"/g;s/,,/,"",/g' t8
   
2. "aa",1,2,3,4,5,"aaa","","ccc","dd","ee",1,2,3,4,"","h"
   
3. [root@localhost awk_and_sed]# awk -F"," '{OFS=",";for(i=1;i<=NF;i++)if($i !~ /^[0-9]/)$i="\""$i"\"";print}' t8
   
4. "aa",1,2,3,4,5,"aaa","","ccc","dd","ee",1,2,3,4,"","h"

:1是标签，你也可以用其他的字符代替。
t1是指s///执行成功时返回标签1处。

echo aa,1,2,3,4,5,aaa,,ccc,dd,ee,1,2,3,4,,h | sed -r 's/([a-z]+)/"\1"/g' | sed -r 's/,,/,"",/g'
"aa",1,2,3,4,5,"aaa","","ccc","dd","ee",1,2,3,4,"","h"
