Created April 7, 2025 06:20

sed & awk for gzip-ed text files.

	#!/usr/bin/env zsh
	# sed & awk for gzip-ed text files.

	# The `zsmartcat` function reads the contents of a file, but it intelligently
	# handles files that are either:
	# 1. Gzip-compressed files (e.g., `.gz` files).
	# 2. Regular text files (uncompressed files).
	# The function decides whether to use `zcat` (to extract and display
	# a gzip-compressed file) or the standard `cat` command (to display
	# an uncompressed text file), based on the file type.
