有关字符串分割的问题
假设有如此字符串：
aa=11|bb=22|cc=33|dd=44
如果我想得到的结果为:
11,22,33,44
该如何处理，谢谢
[解决办法]
shell的话
echo ${aa} | sed s/\|/,/g
[解决办法]
#/bin/bash
result=""
str="aa=11|bb=22|cc=33|dd=44"
strs=$(echo ${str} | sed s/\|/\ /g)
for res in ${strs}
do
ult=$(echo ${res} | awk -F '=' '{print $2}')
if [ "${result}" ]
then
result=${result},${ult}
else
result=${ult}
fi
done
echo ${result}
