在for循环和print的帮助下遍历键对值

Question

尝试设置for循环，其中我可以用相应的键解析值并相应地打印语句

> output.txt
Service1   Running
Service2   Running
Service3   Failed

所需输出:

Service1 is in Running state
Service2 is in Running state
Service3 is in Failed state

Answer 1

当时可以使用循环

while read name state; do
echo "$name is in $state state"
done < output.txt

Answer 2

利用printf重用其格式规范直到输出耗尽的事实

printf "%s is in %s staten" $(cat output.txt)

如果您有bash或zsh可供使用，可以将其写得稍微简单一点:

printf "%s is in %s staten" $(<output.txt)
