Unix CLI - Line Count Function

.bashrc

# -----------------------------------------------
# Specific file type line count function.
# - e.g. great tool for js|css|sass|less|html
# - Tested & working on MacOSX 10.12.*
# - Requirements: Unix based OS & Git.
# Git is needed since I needed a count that 
#     obeys the .gitignore file.
# -----------------------------------------------
# Place this function in your ~/.bashrc file:
# Usage:
# After adding snippet run:
# $ exec bash
# NOTE: Each time you reopen a new MacOS Terminal 
#     you will need to type: exec bash
# From there you can navigate into your project 
#     folder run this snippet with e.g.:
# $ linecount html
# To count all the *.HTML files in your current 
#     directory and it's child directories
function linecount() {
  echo "Checking all $1 documents";
  FILETYPE='.*\.'$1'$';
  TOTALFILES=$(git ls-files | grep $FILETYPE | wc -l | awk {'print $1'})
  echo ">> Total Files: "$TOTALFILES;
  # If no files found, don't continue and exit!
  if [ $(($TOTALFILES)) -gt 0 ]
  then
    grep -c '^' $(git ls-files | grep $FILETYPE) | awk -F ":" {'print $2 " - " $1'}
    TOTALLINES=$(wc -l $(git ls-files | grep $FILETYPE) | grep total | awk {'print $1'})
    echo ">> True Line Count Total: "$(($TOTALLINES+$TOTALFILES));
  else
    echo "No specified file types found, exiting!";
  fi
