如何将数组作为参数传递给 shell 脚本并在 shell 脚本中获取该数组

Question

I have an array of IPs and I want to pass that array as an argument to perform further operations in shell script. I want to know how to pass the array and access in shell script.

eg. ["1.2.22.22","33.2.5.2"]

Answer 1

you can pass the IP addresses as arguments and then make an array inside the script using $@ . this is needed to list each argument as a separate word :

arr-script.sh:

declare -a ARR
ARR=($@)


echo ${ARR[0]}
echo ${ARR[1]}
echo ${ARR[2]}
echo ${ARR[*]}

u can run it this way: sh arr-script.sh IP1 IP2 IP3
