获取终端号码

我正在制作一个迷你欢迎脚本.zshrc。该脚本是（我想$TTYNUMBERGOESHERE用 tty 号码替换，但用一个变量使其在每个终端上自动更新）；

clear
echo "Welcome to Mehmet Akif's Linux!"
echo
echo " * $USER on MadLinux."
echo " * Using $TTYNUMBERGOESHERE."
echo
echo "Type 'startx' to start graphical user interface."
echo

只需使用tty命令：

clear
echo "Welcome to Mehmet Akif's Linux!"
echo
echo " * $LOGNAME on MadLinux."
echo " * Using $(basename $(tty))"
echo
echo "Type 'startx' to start graphical user interface."
echo

或者，更整洁一点：

clear
printf '%s\n\n%s on MadLinux.\nUsing %s\n\n%s\n\n' \
       "Welcome to Mehmet Akif's Linux!" \
       "$LOGNAME" \
       "$(basename $(tty))" \
       "Type 'startx' to start graphical user interface."

或者，使用此处文档：

clear
cat <<EoF
Welcome to Mehmet Akif's Linux!

$LOGNAME on MadLinux.
Using $(basename $(tty))

"Type 'startx' to start graphical user interface."
EoF

实际上，zsh还有一种更简单的获取 tty 名称的方法：$TTY变量。所以你可以使用：

clear
cat <<EoF
Welcome to Mehmet Akif's Linux!

$USER on MadLinux.
Using "${TTY#/dev/}"

"Type 'startx' to start graphical user interface."
EoF
