I need help with my practical assignment on Operating Systems course. The questions revolve around:
1. Analysing the behaviours of three Linux commands (cp, remove and cat);
2. Memory exploitation techniques.
If you're capable in these areas pls let me know. I go pay some small money oo

Hit me up I can help you with this.

Certainly! Let's analyze the behaviors of three commonly used Linux commands: cp, rm (remove), and cat.

cp (Copy):

Purpose:
The cp command is used to copy files or directories from one location to another.
Syntax:
cp [options] source destination
Example:
cp file.txt /path/to/destination/
Behavior:
Copies the specified source file or directory to the destination.
If the destination is a directory, the source is copied into that directory.
Can be used to copy multiple files or directories simultaneously.
Common options include -r for recursive copying and -i for interactive mode.

rm (Remove):

Purpose:
The rm command is used to remove (delete) files or directories.
Syntax:
rm [options] file(s) or directory(s)
Example:
rm file.txt
Behavior:
Deletes the specified file or directory.
Use the -r option for recursively deleting directories and their contents.
The -f option can be used to force deletion without confirmation.
Exercise caution, as deleted files are usually not recoverable, and the operation is irreversible.

cat (Concatenate):

Purpose:
The cat command is used to concatenate and display the content of files.
Syntax:
cat [options] file(s)
Example:
cat file1.txt file2.txt
Behavior:
Concatenates the content of one or more files and displays it on the standard output (usually the terminal).
It can also be used to create a new file by combining the content of existing files.
Commonly used with other commands and operators for various text manipulation tasks.
Options include -n to number lines and -A to show all non-printing characters.

These commands are fundamental in managing and manipulating files and directories in a Linux environment. It's important to use them with caution, especially rm, to avoid unintentional data loss. Always double-check your commands, particularly when using options that can have irreversible effects.

Thanks but this is not a theoretical work ... we are to exploit an OS ..and much more

This has to be the funniest comment here. "...this is not theoretical work..." How the hell can you "exploit an OS" when it's blatantly clear that you do not have a basic knowledge of Linux commands

But these are very dangerous Linux commands he needs help with.

The only real dangerous command here is the rm command. And it's dangerous only if used recklessly. My grouse with the OP is that they a criticizing a response as "theoretical" when it doesn't sound like they even have a basic knowledge of Linux commands. Literally wants someone to spoon feed them.

Expected something worse than foundation shell commands. Can't wait for him to get to ports. I hope he keeps us updated with his assignments.

With chatGPT Linux ports commands are now child's play:

netstat:
netstat -tulpn: Lists all listening ports along with the processes using them.

ss (Socket Statistics):
ss -l: Displays listening sockets.
ss -t -a: Shows all TCP sockets.

nmap (Network Mapper):
nmap <target>: Scans open ports on a target machine.
nmap -p <port> <target>: Scans a specific port on a target machine.

telnet:
telnet <hostname> <port>: Tests connectivity to a specific port on a remote server.

lsof (List Open Files):
lsof -i: Lists all open network connections.

iptables:
iptables -L: Shows the current firewall rules, including port-based rules.

firewalld:
firewall-cmd --list-ports: Lists all open ports managed by firewalld.

nc (Netcat):
nc -zv <hostname> <port>: Checks if a port is open on a remote machine.

socat:
socat TCP-LISTEN:<local-port>,reuseaddr,fork TCP:<target-host>:<target-port>: Forwards traffic from a local port to a remote host.

tcpdump:
tcpdump port <port>: Captures network traffic on a specific port.

lspci:
lspci -nnk | grep -i net: Lists PCI devices, including network adapters.

Thanks all, I got my assignment sorted.
I think i'm too old to start learning Linux now when it may never bring food to my table. I just needed to pass the course anyhow. I got an intern in my office to sort it out.

Good you got it sorted out. However you're not too old to learn, you're not interested.

Did OP ask you about Linux ports?
