Switch branches/tags

Name already in use

A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Are you sure you want to create this branch?

# A wrapper around find to ignore noise directories
#
# ## Usage
#
# `NAME [<flags>] <searchpath> [...other find arguments...]
#
# NAME -h
# NAME .
# NAME ./somepath
# NAME . -type d
# NAME . -type f -name '*.js'
#
# Flag | Description
# ---- | -----------
# -V | Show version.
# -h | Usage and help text.
# -x | Enable xtrace debug logging.
#
# Flags _must_ be the first argument to `NAME`, before `searchterm`.
#
# Patterns to ignore are obtained from reading the following files:
#
# - `$HOME/.ffind`
# - `$PWD/.ffind`
# - `$(git rev-parse --absolute-git-dir)/../.ffind`
#
# The ignore file format is one entry per line, with an expression that
# find can consume. Blank lines and comments (#) are ignored:
#
# # This is a comment.
#
# -path *.git
# -path *node_modules
# -name *.pyc
