遍历以逗号分隔的 python 格式列表

Question

我有 bash 脚本，其中的变量以 python 列表格式存储值：

Business_Unit=["A","B","C,D","EF"]

并且需要循环获取：

A
B
C,D
E F

该脚本应将逗号、空格和任何特殊字符放在双引号内。 我试过使用 sed，IFS，但它也在字符串中拆分逗号行。

Answer 1

Sed 帮我做了：

echo "$Business_Unit" |
sed 's/^[^"]*"//;s/"\]//;s/","/\n/g' |
#    ----------- ------- ----------
#       |           |        |
#       |           |       substitute "," by a new line
#       |          remove the last quotes and ]
#       remove everything upto and including the first " 
while read line ; do
    echo "$line"
done

Answer 2

string='Business_Unit=["A","B","C,D","E F"]'
awk -F\" '{for(i=2; i<=NF; i+=2) print $(i)}' <<< $string
A
B
C,D
E F
