Answer 1

你可以试试下面的命令吗？

 awk '{for(i=1;i<=NF;i++) {printf "%s ", $i}; printf "\n"}' | xargs rm

Answer 2

there are many ways, I think the simplest will be

$ vars="name1 name2 name3"
$ for v in $vars; do echo $v; done
name1
name2
name3

change echo to your script.

Answer 3

You can use xargs :

queues="q1 q2 q3 q4"
echo ${queues} | xargs -n1 echo "Remove"
