Commands In Terminal

Command Line

Using cd

No Args Working Directory - /home

[user@sahara ~]$ cd 
[user@sahara ~]$

Puts user in home directory, doesn’t do anything since already in home directory. This is not an error.

Directory Working Directory - /home

[user@sahara ~]$ cd lecture1/
[user@sahara ~/lecture1]$

Changes Directory to the directory specified in the argument, which we can see from the change in prompt. This is not an error.

File Working Directory - /home/lecture1

[user@sahara ~/lecture1]$ cd messages/en-us.txt 
bash: cd: messages/en-us.txt: Not a directory

Cd only allows us to move to directories not actual files, so this produces a error message telling us that the thing we tried to cd into wasn’t a directory. This is an error.

Using ls

No Args Working Directory - /home

[user@sahara ~]$ ls
lecture1

Using ls without any arguments shows us the files and folders of our current directory. This is not an error.

Directory Working Directory - /home

[user@sahara ~]$ ls lecture1/
Hello.class  Hello.java  messages  README

This shows us the files and folders within the directory we put as the argument. This is not an error.

File Working Directory - /home

[user@sahara ~]$ ls lecture1/Hello.class 
lecture1/Hello.class

When we ls into a file it just shows us the relative path to the file from the directory where it was called. This is not an error.

Using cat

No Args Working Directory - /home

[user@sahara ~]$ cat
hi
hi
test
test

Produces empty line and duplicates anything I enter into the command line, I believe this is due to the cat reading the terminal and once we input it, it reads it back out. This is not an error.

Directory Working Directory - /home

[user@sahara ~]$ cat lecture1/
cat: lecture1/: Is a directory

When we run cat on a directory it produces an error message telling us that it is a directory so it can’t read us anything from it. This is an error.

File Working Directory - /home/lecture1

[user@sahara ~/lecture1]$ cat messages/fr.txt 
Bonjour le monde!

When we use cat on a file it reads us the content from the file we selected in the argument. This is not an error.
