NAME
cleanname - clean a path name
SYNOPSIS
cleanname [ -d pwd ] names ...
DESCRIPTION
For each file name argument, cleanname, by lexical processing only, prints the shortest equivalent string
that names the same (possibly hypothetical) file. It eliminates multiple and trailing slashes, and it
lexically interprets . and .. directory components in the name. If the -d option is present, unrooted
names are prefixed with pwd/ before processing.
