How can you search for a char in a string in bash?

If I have a string var="root/Desktop", how can I determine whether var var contains a '/' character?

echo "${var1}" | grep '/' should work.

The portable solution that works in any Bourne-heritage shell and needs no expensive forks or pipes:

 case $var in
   (*/*)   printf 'Has a slash.\n';;
   (*)     printf 'No slash.\n';;
 esac

Bash can match against regular expressions with =~, try:

[[ $var =~ "/" ]] && echo "contains a slash"
