CoreUtils in Typescript

Description

Goal is to reimplement several core Unix utilities, giving exposure to Typescript basics, including file I/O, flag parsing, string manipulation, and more.

Requirements

• [] Create Typescript programs that replicate the functionality of the following Unix utilities:

  • [ ] head
  • [ ] tail
  • [ ] wc (word count)
  • [x] cat
  • [x] echo
  • [ ] tree
  • [x] env
  • [x] true
  • [x] false

• [x] Each utility should be implemented as a separate python program.

• [x] Programs should read input from files or stdin as appropriate.

• [x] Implement basic flags for each utility where applicable.

Example Implementations

1. head

• Print the first 10 lines of input by default.
• Add a -n flag to specify the number of lines to print.

2. tail

• Print the last 10 lines of input by default.
• Add a -n flag to specify the number of lines to print.

3. wc (word count)

• Count lines, words, and characters in the input.
• Add -l, -w, and -c flags to display only lines, words, or characters respectively.

4. cat

• Concatenate and print files.
• Add a -n flag to number output lines.

5. echo

• Print arguments to standard output.
• Add a -n flag to omit the trailing newline.

Acceptance Criteria

• Each utility is implemented as a separate Python program.
• Includes basic error handling.
• Includes a README with build and usage instructions for all utilities.
