shell如何把字符串切割为数组

Posted 2023-03-28

参考技术A root@localhost:~/xly# sh 1 hello
abc
shell
haha
1 hello abc
2 shell
3 haha
root@localhost:~/xly# vim 1
#!/bin/bash
string="hello abc,shell,haha"
OLD_IFS="$IFS"
IFS=","
array=($string)
IFS="$OLD_IFS"
for var in $array[@]
do
echo $var
done

echo $string | awk 'split($0,arr,",");for(i in arr) print i,arr[i]'

用awk更加精准
