Bash脚本：处理参数

Question

bash / shell大师可以帮我制作一个非常简单的bash脚本来处理以下内容 - 我很难让它按照这些方式工作

输入如下

./script #channel1,#channel2,#channel3 "This is the message"  

或者更容易..

./script #channel1,#channel2,#channel3 -m This is the message

（-m之后的任何内容都是消息）

现在我想循环遍历每个频道，并回显消息，即

for channel in channels
    echo channel $message
fi

感谢

Answer 1

如果你正在写它，那就更容易了

usage ()
{
  echo "usage: $0 <MESSAGE> <CHANNELS>"
  exit
}

[[ $3 ]] || usage
message=$1
shift

for channel
do
  echo $channel $message
done

Answer 2

channels=$1
message=$2
IFS=,
for channel in $channels
do  echo $channel $message
done

示例：

0>./script channel1,channel2,channel3 "This is the message"
channel1 This is the message
channel2 This is the message
channel3 This is the message
