What are other common file commands?

Beyond cat and wc, there are several essential commands you'll use every day in Linux to manage files. Here are the most common ones categorized by what they do:

1. Moving and Renaming

mv (Move): Used to move a file to a different folder or to rename a file.

mv old_name.txt new_name.txt  # Renames the file
mv notes.txt /tmp/           # Moves file to /tmp directory

cp (Copy): Creates a duplicate of a file.

cp /tmp/hello ./hello_backup  # Copies 'hello' to your current folder

2. Creating and Deleting

touch: The quickest way to create a new, empty file.
```
touch empty_file.txt
```
rm (Remove): Deletes a file. Be careful: there is no "Trash Can" in the command line!
```
rm file_to_delete.txt
```

3. Searching Inside Files

grep: Searches for a specific string of text inside a file.
```
grep "Labby" /tmp/hello  # Finds lines containing "Labby"
```

4. Comparing Files (Crucial for this Lab!)

Since your lab is titled "File Contents and Comparing," these two are very important:

diff: Compares two files line by line and shows you the differences.
```
diff file1.txt file2.txt
```
cmp: Checks if two files are exactly identical. If they are the same, it returns nothing.

5. File Information

file: Tells you what type of file it is (e.g., text, executable, or image).
```
file /tmp/hello
# Output: /tmp/hello: ASCII text
```
stat: Provides detailed information about the file, such as when it was last modified and its size.
```
stat /tmp/hello
```

Summary Table for Quick Reference:

`cp`	Copy a file
`mv`	Move or Rename a file
`rm`	Delete a file
`grep`	Search text within a file
`diff`	Show differences between two files

Which of these would you like to try out in your current environment? diff is a great one to practice next!
