# Note: Below, when I say "run the bare command", this means typing the function name into Terminal without adding any parameters.

# 'lsod' stands for 'list only dirs'. The command is taken from the comment by Gergo in "[Listing only directories using ls in bash: An examination](https://stackoverflow.com/questions/14352290/listing-only-directories-using-ls-in-bash-an-examination)".

# "bff" is "Bash functions file". This command shows the current file so that you can look up the names of all the other custom aliases and functions.
# Usage: just run the bare command from anywhere

# Usage: just run the bare command from anywhere

# "myt" stands for "my todos for the current year". The name is short so that it's fast to type.

# mygrep amazon

# Example usage:
# myhtmlgrep "insect suffering"
# HTML files sometimes don't have enough newlines, causing the `grep` matching lines to be too long. This command only prints out up to 30 characters before and after the match. The second `grep` serves to color the text actually being searched for, rather than the entire output including the 30 characters before and after. This command is based on Stéphane Chazelas's answer on "[To grep 20 characters after and before match](https://unix.stackexchange.com/questions/121450/to-grep-20-characters-after-and-before-match)".
myhtmlgrep() { grep -rinoE --include \*.html --include \*.htm --include \*.php --exclude-dir=vxhx ".{0,30}$1.{0,30}" . | grep --color "$1"; }

# The `grep -v` omits this file itself from being included in the results. The final `grep` serves to re-highlight the grepped-for string after `sort` and `grep -v` have removed the original highlighting. At the end we go to the `mytodos` folder because after seeing these search results, that's the most likely place we'll want to be, since we can open a lot of todo files from there.
