#!/bin/bash # This is the first Bash shell program # Scriptname: greetings.sh echo echo -e"Hello $LOGNAME,Ic" echo "it's nice talking to you. echo -n "Your present working directory is: pwd # Show the name of present directory echo echo -e"The time is date +%T!.\nBye' echo

这段代码有几个语法错误，需要修正。下面是修正后的代码：

#!/bin/bash

# This is the first Bash shell program
# Scriptname: greetings.sh

echo
echo -e "Hello $LOGNAME,\nIt's nice talking to you."
echo "Your present working directory is: $(pwd)" # Show the name of present directory
echo -e "The time is $(date +%T)!\nBye."

这段代码会输出如下内容：

Hello username,
It's nice talking to you.
Your present working directory is: /path/to/working/directory
The time is 09:30:00!
Bye.

其中，`username` 会被替换为当前用户的用户名，`/path/to/working/directory` 会被替换为当前工作目录的路径，`09:30:00` 会被替换为当前时间。
