导读：我有一些 shell命令.我想将输出写入标准输出并将其保存为变量. 我想用一个命令来解决它. 我试过这些东西 ls $VAR # redirects the output to file which name is stored in $VARls | tee -a $VAR # writes to standard output as well as in file which name

我有一些 shell命令.我想将输出写入标准输出并将其保存为变量.
我想用一个命令来解决它.
我试过这些东西

ls > $VAR          # redirects the output to file which name is stored in $VAR
ls | tee -a $VAR   # writes to standard output as well as in file which name is stored in $VAR
VAR=`ls`           # output into $VAR,but it is not sent to standard output
VAR=`ls`;echo $VAR # ok,it works but these are two commands

任何想法？

怎么样：

VAR=$(ls | tee /dev/tty)
