Question

I am new to shell scripting. I have a variable containing path to specific file. I want to check if this variable has any spaces in it.

I tried with

  if [[ ${VAR} = "${VAR% *}" ]] ; then
      echo "contains spaces"
  else
      echo "doesnot contain spaces"
  fi

But it doesn’t work. Any help will be really appreciable.

Answer 1

or

case ${VAR} in
  *\ * ) echo "VAR=$VAR has at least one space char" ;;
  * ) echo "VAR=$VAR has no space chars" ;;
esac
