I have a string containing many words with at least one space between each two. How can I split the string into individual words so I can loop through them?

The string is passed as an argument. E.g. ${2} == "cat cat file". How can I loop through it?

Also, how can I check if a string contains spaces?

For checking spaces just with bash:

[[ "$str" = "${str% *}" ]] && echo "no spaces" || echo "has spaces"
