du
du - disk usage Using du to Check File Sizes To see the size of a specific file or directory, use the following syntax:
Check a single file:
1
du filename.txt — Shows the disk space used by a specific file.
Human-readable format:
1
du -h filename.txt — Displays size in KB, MB, or GB (e.g., 4.0K instead of just a number).
Check all files in a directory:
1
du -ah /path/to/directory — The -a (all) flag forces du to list individual files, not just directories.
Summarize a directory:
1
du -sh /path/to/directory
1
— The -s (summarize) flag shows only the total size of the directory without listing every item inside.

Flag Description
-a All: Shows sizes for files as well as directories.
-h Human-readable: Formats sizes in K, M, and G.
-s Summarize: Displays only a total for each argument.
-c Total: Adds a "grand total" line at the bottom.
--max-depth=N Limits the output to
levels deep into subdirectories.
Example: du
1
du -h readme
#
SSH
Example : SSH
1
ssh -p 2220 bandit0@bandit.labs.overthewire.org
#
Find
Using cat to Display the Entire File Content The cat command is used to display the entire content of a file to the standard output. bash
Example: Find
1
find /path/to/search -name "filename.txt" -exec cat {} \;
1
find /home/bandit0 -name "readme" -exec cat {} \;
#
File
Determining File Type To determine the type of a file, use the file command followed by the filename: bash
1
file <filename>
Example output:
data.txt: ASCII text or program: ELF 64-bit LSB executable.
#
nano
Text Editors: You can also use terminal-based text editors to open and read (as well as edit) files. nano is considered more user-friendly for beginners than vim or emacs.
Example: nano
1
2
nano <filename>
nano readme
#
CAT
Displays the entire content of a file to the terminal screen at once. This is best for short files. Example:
1
cat readme
#
Less and More
less and more (pagers): Display the file content one screen or “page” at a time, allowing you to scroll through large files. less is generally preferred as it allows both forward and backward scrolling (use space for the next page, arrow keys to scroll, and q to exit).
Example :
1
less <filename>
#
head and tail
(partial view): Show only the beginning or end of a file, respectively. By default, they display the first or last 10 lines, which is especially useful for quickly previewing a file or monitoring log files.
Example:
1
2
head <filename>
tail <filename>
#
TIP: Create a file for notes and passwords on your local machine!
Passwords for levels are not saved automatically. If you do not save them yourself, you will need to start over from bandit0.
Passwords also occasionally change. It is recommended to take notes on how to solve each challenge. As levels get more challenging, detailed notes are useful to return to where you left off, reference for later problems, or help others after you’ve completed the challenge.
