编写一个 shell 脚本来显示当前登录的用户数并将计数写入“count.txt”。 显示count.txt文件内容

Question

Display count of users currently logged in and write the count in count.txt . Display the count.txt file content.

I used this but it's not giving the right answer.

ls -l | wc > count.txt
cat count.txt

Answer 1

As said by @Barmar ls -l is not a correct command to have the number of users logged in.

Try w command. So thi muse looks like this:

w -h| wc > count.txt
cat count.txt

The -h argument is to remove headers line.

Answer 2

who | wc -l > count.txt;
cat count.txt

Answer 3

This will work -

who | wc> count.txt

cat count.txt
