gitignore

#!/bin/bash
# To add two items to the current .gitignore file:
# gitignore '*.swp' bin
#
# To sort and de-dupe the current .gitignore file:
# gitignore

GITIGNORE=.gitignore;

# create ignore file if necessary
if [ ! -f $GITIGNORE ] ; then
  touch $GITIGNORE;
  echo "$GITIGNORE created"
fi

# Append each argument to its own line:
for item in "$@"; do
    echo "$item" >> $GITIGNORE;
done

# Remove duplicates (and sort):
sort -u $GITIGNORE -o $GITIGNORE
