public text v1 · immutable I would like to add to more test elements
1. there must be at least one Upper Case character
2. there are no no single one character space separated items
examples:
1=hello world = bad
1=Hello w = bad
1=Hello World = good
if [[ $1 = *\ * ]] && [[ ! $1 = *@* ]] && [[ ! $1 = *=* ]]
then
echo 1
fi
