bash-3.2$ read
~/.bash_profile
bash-3.2$ echo "$REPLY"
~/.bash_profile
bash-3.2$ ls $REPLY
ls: ~/.bash_profile: No such file or directory
bash-3.2$ ls "$REPLY"
ls: ~/.bash_profile: No such file or directory

如何让这个目录展开？

这里搞错了，REPLY 是一个数组，反正了解意思就行。

echo "${REPLY[0]}"
echo "${REPLY[@]}"

修正第一条append: REPLY不是数组。
https://www.gnu.org/software/bash/manual/html_node/Bash-Builtins.html#index-read

read [-a aname] [name …] 想要数组的话使用 -a Option

If no names are supplied, the line read is assigned to the variable REPLY.

powershell on linux：

PS /root> $REPLY='~/.bash_profile'
PS /root> ls $REPLY
/root/.bash_profile
PS /root> ls -l $REPLY
-rw-r--r--. 1 root root 176 12 月 29 2013 /root/.bash_profile
PS /root>
