1 问题
我们有段字符串data="chenyu:chenzixuan:chenzi",我们需要通过:分割,我们可以采用IFS
我们可以采用下面的模板
oldIFS=$IFS
IFS=":"
for item in $data;
do
*******
done
IFS=$oldIFS
2 代码实现
#/bin/bash
data="chenyu, chencaifeng, chenzixuan, chenzixi"
oldIFS=$IFS
IFS=", "
for item in $data;
do
echo Item:$item
done
IFS=$oldIFS
line="chen:gong:yu:chen:cai:feng";
oldIFS=$IFS
IFS=":"
count=0
for item in $line;
do
[ $count -eq 0 ] && user=$item
[ $count -eq 4 ] && name=$item
# count=$[$count + 1];
let count++
done
IFS=$oldIFS
echo $user
echo $name
3 运行结果
Item:chenyu
Item:chencaifeng
Item:chenzixuan
Item:chenzixi
chen
