Unix-like commands

Here's a list of commonly used global options across various Unix-like commands and their purposes:

-h: Human-readable format (e.g., sizes in ls or df).

--help: Displays help information about the command.

--version: Shows version information about the command.

-v: Verbose output; provides more detail.

-q: Quiet mode; suppresses output or warnings.

-f: Force an action, ignoring warnings or errors.

-r: Recursive; applies the command to directories and their contents.

-R: Recursive; similar to -r, used in commands like cp and ls.

-i: Interactive mode; prompts before taking action (e.g., rm -i).

-a: Include all files, including hidden ones (e.g., ls -a).

-l: Long format; provides detailed information (e.g., ls -l).

-c: Use ctime or creation time (e.g., ls -lc).

-t: Sort by time (e.g., ls -lt).

-u: Use access time (e.g., ls -lu).

-d: Show directories themselves, not their contents (e.g., ls -d).

-p: Append a / to directory names (e.g., ls -p).

-n: Show numeric user/group IDs (e.g., ls -n).

-s: Summarize disk usage or sizes (e.g., du -sh).

-e: Expand or escape sequences (e.g., echo -e).

-b: Show byte offsets (e.g., grep -b).

-u: Update files (e.g., cp -u only copies if source is newer).

-m: Output as a comma-separated list (e.g., ls -m).

-A: Similar to -a, but excludes . and .. (e.g., ls -A).

-H: Follow symbolic links listed on the command line (e.g., find -H).

-L: Follow symbolic links (e.g., cp -L).

-S: Sort by file size (e.g., ls -S).

-T: Specify tab width (e.g., ls -T).

-p: Add a slash (/) to directory names (e.g., ls -p).

-X: Sort by extension (e.g., ls -X).

-z: Compress or decompress files (e.g., gzip -z).

Options can vary by command, so always consult the command’s manual (man command) for specifics.

In a world of words, where truths are told,
I stand apart, with a heart of gold.
I don't believe it, I don't live it,
A skeptic's soul, with a spirit to give.
I don't buy it, the lies they sell,
The promises that only time can tell.
I don't want it, the facade they wear,
For authenticity is what I declare.
In a sea of noise, where voices rise,
I seek the truth, with open eyes.
I don't believe it, the tales they spin,
For honesty is where my heart begins.
I don't live it, the life they claim,
A life of pretence, a life of shame.
I don't buy it, the dreams they sell,
For in my heart, I know what's real.
I don't want it, the world's disguise,
For in simplicity, I find my prize.
So let the world keep its illusions grand,
I'll walk my path, with a steadfast hand.
For truth is beauty, and beauty is rare,
And in its light, I find my care.
So I don't believe it, I don't live it,
I don't buy it, I don't want it.

Multi-boot
Always install Windows first
Windows does not detect other operating systems and does not feature a boot menu. When you install it, it overwrites your boot sequence and your computer then boots straight into Windows.

Linux Mint (and most Linux distributions) detects other operating systems and builds a menu from which you can choose which system to boot.

For this reason, if you want to dual-boot or multi-boot with Windows, it is easier and recommended to install Windows first, before you install Linux Mint.

why npm pnpm be eating you ram!!!!!!!!!!!!!!!!!

High Concurrency: Node.js handles many simultaneous connections in a single thread, increasing memory usage compared to PHP or Go, which use multi-threading or separate processes.

Large Data Handling: Node.js may keep large datasets in memory longer due to its non-blocking nature, whereas PHP processes typically handle data in short-lived scripts and Go uses efficient concurrency with goroutines.

Heavy Dependencies: Node.js applications often have many dependencies, increasing memory usage, while PHP and Go tend to have fewer or more optimized dependencies.

Memory Leaks: Node.js's single-threaded event loop can amplify the impact of memory leaks, while PHP's separate process model and Go's garbage collection may mitigate their effects.

Long-lived Processes: Node.js apps are often long-running, maintaining state and connections, whereas PHP scripts are typically short-lived and Go's efficient memory management helps handle long-lived processes better.
