No.1 sl
I believe everyone has used the ls command, but what will be the effect if you accidentally type sl on the Linux command line?
Of course it may be this effect, let's install it and try it.
mgm@ubuntu:~$ sl
The program 'sl' is currently not installed. You can install it by typing:
sudo apt install sl
Ok? Prompt error
mgm@ubuntu:~$ sudo apt-get install sl
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
This situation is because apt is running, check the situation
mgm@ubuntu:~$ ps afx|grep apt
677 ? Ss 0:00 /bin/sh /usr/lib/apt/apt.systemd.daily
2362 pts/0 S+ 0:00 \_ grep --color=auto apt
2118 ? SNl 0:00 /usr/bin/python3 /usr/sbin/aptd
kill them
mgm@ubuntu:~$ sudo kill -9 677
mgm@ubuntu:~$ sudo kill -9 2362
mgm@ubuntu:~$ sudo kill -9 2118
Then continue to download and install.
After installation, enter sl, Oh yeah ~ a steam locomotive whizzes by
No.2 Star Wars
I believe everyone hasn't seen a movie for a long time, right? You probably have never seen the ASCII version of the movie. Let’s enjoy the free ASCII version of Star Wars online.
When the Internet first started, the telnet version of the BBS forum was quite popular. Today, let’s experience it.
mgm@ubuntu:~$ telnet towel.blinkenlights.nl
Wait a moment, after the letters, the excitement continues.
Remember, the exit is "Ctrl+]", and then enter quit at the telnet prompt
