How to use the specified separator to split a string so that the result is an array of strings, similar to split in java, and the split keyword has been left for file segmentation, so the string segmentation process cannot be used. So how to handle string segmentation? There are two methods
1. For strings that do not contain spaces, use the following method
Method 1
#!/bin/bash
string="hello,shell,haha"
array=(${string//,/ })
for var in ${array[@]}
do
echo $var
done
Method 2
#!/bin/bash
string="hello,shell,haha"
OLD_IFS="$IFS"
IFS=","
array=($string)
IFS="$OLD_IFS"
for var in ${array[@]}
do
echo $var
done
Method 3: Use the tr instruction to implement character replacement
#!/bin/bash
string="one,two,three,four,five"
array=(`echo $string | tr ',' ' '` )
for var in ${array[@]}
do
echo $var
done
2. For strings containing spaces, use the following method
#!/bin/bash
str='this is a good question, hello shell, look at me, show your enthusiasm'
i=1
while((1==1))
do
splitchar=`echo $str|cut -d "," -f$i`
if [ "$splitchar" != "" ]
then
((i++))
echo $splitchar
else
break
fi
done
