dear all,
i am trying to check if there are any files named file* (e.g.
file_001.txt file1.doc) in my directory.
if( -e "file*" ) { print("true\n"); } # this doesn't work
else { print("false\n"); }
if( -e "m/^file/" ) { print("true\n"); } # this doesn't work either
else { print("false\n"); }
Ouch, there's the dreaded "doesn't work"! (c.f.
http://perl.plover.com/Questions4.html) Fortunately, you told us what
you are after, so the question can be answered.
-e only takes a single filename.
You need a glob:
print "Found!" if glob('file*');
Or the slightly deprecated:
print "Found!" if <file*>;
