Howto

Script only puts some bash code at .bash_profile to cd locked directory, like that:

# lock bash
LOCK_FILE=#LOCK_FILE#/.lockbash

if [ -f $LOCK_FILE ]; then
  DIR_TO_LOCK=$(cat $LOCK_FILE)
  eval REALPATH=$DIR_TO_LOCK  # to expand "~/dir", for example

  if [ -d $REALPATH ]; then
    cd $REALPATH
    echo "Locked to $DIR_TO_LOCK"
  fi
fi

With remove option, script deletes lockbash file and it removes code from .bash_profile file.
