I learned about a bug in the alpha test version 00.01.00 of the gulam shell the hard way. Somehow I managed to create a file called ">foo.c" when I fooled around with redirection. The directory where this happened contained some other C-programs, one of them called foo.c. When you do a "ls *.c" in that folder, gulam expands to: "ls >foo.c bar.c something.c foo.c" resulting in a directory list in foo.c, its old contents are gone. Is this a feature of gulam ??? I think its a bug, a filename, however strange it may be, must not lead to a redirection. foo.c is gone forever. BTW, I checked it with the csh on UNIX, which behaves as expected, if you say "ls *.c" you get a list containing the files ">foo.c" and "foo.c". foo.c is not trashed. Is this fixed in later versions of gulam ?? Gerhard Pehland UUCP: ...!seismo!unido!qtecmuc!ger

Gulam is a very nice shell, but this is obviously alpha version and IT HAS number of bugs (or places with a weird behaviour :-)). For example, try to copy a file to a write protected floppy. Gulam will happily ablige, but instead to disk it will dump the file to your own screen. You may even argue, that this is a "feature" for text files, but if you are dealing with 100K binary results may be (hm...) rather interesting. An attempt to break the operation will crash your computer with 2 bombs. I have also experienced strange crashes after 3 or 4 file transfers. It does not matter if I was using a built-in xmodem, or some external program. They were triggered by something innocent, like "ls" and ended up with two, three or four bombs (a phase of the moon, I suppose). Other things. If you will swap floppies, a new one won;t be recognized utntil you will switch to its root directory and execute "ls" command. "rehash" has sometimes beneficial effects, but not allways. A file >foo.c was probably created by an attempt append stdout to foo.c, by typing somthing like "ls >>foo.c". This does not work! At lest not the way you would think so that it would. I also miss an option of saving te session in a file. But I still like it. :-). Does somebody kepp track of all these things. I am sure theat they were rediscovered 100 times.
