Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesStart with eight short commands, each tied to a job: pwd tells you where you are, ls shows what is there, and cd takes you somewhere else. For files, remember cp to copy, mv to move or rename, and rm to remove. cat displays file contents; grep searches text. The names are brief, but the safest way to learn them is to connect each one to its action and check paths before changing files.
Find your place and navigate
pwd: Where am I?
pwd prints the shell’s current working directory. Use it when you are unsure which folder a relative path will refer to. GNU Coreutils 9.11 documents pwd in its manual.

pwd
ls: What is here?
ls lists directory contents. To make each entry appear on its own line, use ls -1, an option described in the ls(1) manual page.

ls -1
cd: Go to another directory
cd changes the shell’s current directory. Unlike the other commands here, it is a shell builtin: the shell must update its own working directory. For example, cd Documents attempts to enter a directory named Documents inside the current directory. The Calvin University Linux quick reference groups it with navigation commands.
#1 Best Overall
cd Documents
Read a file or search its text
cat: Print file contents
cat concatenates files and writes their contents to standard output, so it can display a short text file in the terminal:
cat notes.txt
For a large file, use a pager so you can read it a screen at a time rather than sending all its contents into the terminal at once. A beginner-oriented example of cat appears in the Calvin University quick reference.
Rank #2
grep: Find matching text
grep searches for text matching a pattern. A simple starting example searches a file for the word error:
grep error app.log
The Calvin University quick reference introduces it for pattern searches. Its detailed behavior depends on the pattern and implementation; consult the documentation for the version on your system when you need more than a basic search.
Rank #3
Copy, move, rename, or remove files
cp: Copy
cp copies files. With two filenames, GNU cp copies the first file to the second, as described in its invocation documentation.
cp draft.txt draft-backup.txt
mv: Move or rename
mv moves files, and using it with a new name in the same directory renames a file. GNU documents these basic operations in its overview of basic file operations.
Rank #4
mv draft.txt archive/draft.txt
rm: Remove
rm removes files or directories. It can make a lasting change, so inspect the path before pressing Enter; a misspelled or unintended target may not be recoverable from the command itself. GNU describes its removal operations in the same basic operations documentation.

Remember the commands by their jobs
| Task | Command | Memory cue | Effect |
|---|---|---|---|
| Check location | pwd |
Print working directory | Displays information |
| List contents | ls |
List | Displays information |
| Change location | cd |
Change directory | Changes the shell’s current directory |
| Display file text | cat |
Think of viewing a file’s contents | Outputs content |
| Search text | grep |
Search for a match | Finds matching text |
| Copy a file | cp |
Copy | Creates a copy |
| Move or rename | mv |
Move | Changes a file’s location or name |
| Remove | rm |
Remove | Deletes a file or directory |
The most direct memory links are ls to list, cp to copy, mv to move, and rm to remove. Keep the navigation pair together: pwd answers “where am I?” and cd changes where the shell is working.
Best Value
Check before commands that change files
pwd, ls, cat, and grep primarily inspect or display information. cp creates a copy, mv changes location or name, and rm removes a target. Before a file-changing command, verify both the command and the path; take particular care with rm.
These descriptions are grounded in GNU Coreutils documentation for the covered utilities; its manual identifies itself as authoritative for those utilities. That does not make every detail universal: available shells, command implementations, options, and distributions can differ. cd is a shell builtin, and the beginner examples for cat and grep here are task-level guidance rather than a complete account of their options.
