Checking if a directory exists using bash

The script to solve this issue is really easy to do and understand.

The first example checks if a directory exists and the second one if the directory does not exists:

if [ -d "$DIR" ]; then
  echo "Directory exists"
fi
Or to check if a directory doesn't exist:

if [ ! -d "$DIR" ]; then
  echo "Directory does not exists"
fi

For the negative we just use ! at the beginning.

If you are using symbolic links, the previous script will not work the proper way in some situations. The following bash script check if the path is a sym link:

if [ -d "$LINK_OR_DIR" ]; then 
  if [ -L "$LINK_OR_DIR" ]; then
    echo "Symbolic link found"
  else
    echo "Directory found."
  fi
fi
