Add count Command to User Space

[ajsdkty3]

Objective: Implement the count command to provide basic file content statistics.

Description:

count Command: The count command counts the number of lines, words, and characters in a specified file.

Features:

Content Statistics: Count lines, words, and characters in a file.
Options:
-l: Count lines.
-w: Count words.
-c: Count characters.
-h: Display help information on usage.
Approach: Update user space to introduce the count command. Implement functionality to read file content and calculate the number of lines, words, and characters based on command-line options. The count command will parse arguments to determine which statistics to output. If the -h argument is used, count will output simple help information and exit.

Files to be modified/added:

user:
count.c (new file for implementing the count command)
Future Development:

Enhance the command to support counting specific patterns or strings within the file.

A lot of these features are already supported by the built in wc command. Maybe you can enhance it instead? man wc on a Linux machine will give you some inspiration.

Thanks for the suggestion! I've taken your advice and enhanced the wc command:

Objective: Enhance the wc command by adding a feature to count punctuation, digits, and uppercase/lowercase letters in a file.
Description:
wc Command Enhancement: Extend the existing wc to include additional features such as counting punctuation marks, digits, and the number of uppercase and lowercase letters in a file.

Features:
Character Type Counting: In addition to counting lines, words, and characters, this enhancement will allow the user to count:
Punctuation marks (e.g., ., ,, !, ?).
Digits (0-9).
Uppercase letters (A-Z).
Lowercase letters (a-z).
Options:
-l: Count lines.
-w: Count words.
-c: Count characters.
-p: Count punctuation marks.
-d: Count digits.
-u: Count uppercase letters.
-L: Count lowercase letters.

Approach:
Modify the wc command to parse new arguments for counting punctuation (-p), digits (-d), uppercase letters (-u), and lowercase letters (-L).
Implement functionality to read the file and count these additional features along with existing lines, words, and characters.
If the -h argument is used, the wc command will display help information, including details about the new counting features.
Files to be modified/added:
user:
wc.c: Modify the existing file to include the new options and associated functions
Future Development:
Enhance the feature to allow users to count more specified symbols
