循环通过逗号分隔的Python-Format列表

Question

我有带有可变存储值的bash脚本，以python list格式：

business_unit = [“ a”，“ b”，“ c，d”，“ e f”]，

并且需要循环要获得：

A
B
C,D
E F

脚本应将逗号，空格和任何特殊字符保留在双引号中。我已经尝试使用sed，ifs，但是它也在弦乐中分配逗号的线。

Answer 1

SED为我做到了：

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
