sed & awk for gzip-ed text files.

gz_smart_cat.zsh

#!/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.
zsmartcat() {
  if file "$1" | grep -q 'gzip compressed'; then
    zcat "$1"
  else
    cat "$1"
  fi
}

zawk() {
  zcat "$1" | awk "${@:2}"
}

# Directory sed a gzip-ed text file.
zsed() {
  zcat "$1" | sed "${@:2}"
}
