shell中使用内置命令select生成程序菜单的例子，以下的脚本可以提供给用户一系列的选项去选择。
其中定义的finished选项挺好。
复制代码代码如下:
#!/bin/bash
directorylist="Finished $(ls /)"
PS3='Directory to process? ' # Set a useful select prompt
until [ "$directory" == "Finished" ]; do
printf "%b" "annSelect a directory to process:n" >&2
select directory in $directorylist; do
# User types a number which is stored in $REPLY, but select
# returns the value of the entry
if [ "$directory" = "Finished" ]; then
echo "Finished processing directories."
break
elif [ -d "/$directory" ]; then
echo "You chose number $REPLY, processing $directory ..."
# Do something here
break
else
echo "Invalid selection!"
fi # end of handle user's selection
done # end of select a directory
done # end of while not
