# Homemade Unix commands

These C programs emulate some Unix commands. They were made by me in 2022 to practice C language.

My implementations do not claim to be an alternative to the original ones.

## Setup

Showing an example of `ls`

1. Compile the executable:

  ```bash

  gcc ls.c -o ls 

  ```

2. Run the executable:

  ```bash

  ./ls /insert/your/dirname/here

  ```

3. Enjoy!

## List of commands

### ls

- `ls [-al] [file]`

- `ls` only accepts a *single* file or directory as an argument, although in Unix it is possible to accept more than one;

- `-a` option completely mimics the original one: it displays all files and directories starting with a dot;

- `-l` option mimics the `-1` option from the original. It displays all files and directories line by line.

### tail

- `tail [+-n] [file1] [file2] [file3] ... [fileN]`;

- `tail` accepts *multiple* files as an argument;

- `-n` option displays `n` last lines (`n = 10` by default);

- `+n` option displays file from the `n`-th line.
