Aside from the spaces around the equals sign, and the problem that a
filename with no dot leads to a syntactically incorect test, why not
just use shell globbing, like

for file in *.prt{,.*}

You'd want to check if the files exist, like

[ -f "$file" ]

to catch wildcard patterns that don't match anything.
