copland.udel.edu%The UNIX commands described below should be entered after this UNIX prompt, not in the pico editor or the pine e-mail program!.
This guarantees that you are in your root directory. Note that UNIX is a fairly terse operatiny system; no indication is provided that anything has happened!
(list contents of directory)
Please note: This is an "ell": l and this is a "one": 1
(list - long)
This listing is in a longer form that shows more information, such as file permission settings and creation dates. Note that the "space" between ls, the UNIX command, and -l, the option is essential. "Spaces" are used to delimit the name of the UNIX command, its options, and the filename(s) on which it operates.
(list - all)
This listing shows all files, including hidden files which have filename starting with a period.
This Combines the two special actions to ls. You may find additional possibilities by checking the online manual for ls by entering man ls at the UNIX prompt.
You may apply ls to specific files.
This removes the image of core memory dumped from a previous program failure. I've noticed that some student login difficulties originate with disk space problems; the file core is often the culprit!
Again, note that the "space" between pico, the UNIX command, and SCEN103, the filename to be edited, is essential. "Spaces" are used to delimit the name of the UNIX command from the filename on which it operates.
Be creative, but not too long-winded! Don't forget the leading period in the filename.
chmod go+r .plan
-- (This adds read premission to your .plan file.)
(You may read through
if you would like to learn more about the chmod command.)
chmod go+r .signature
signature-file = .signature-- .signature will also be automatically appended to messages if that line already reads
signature-file = <No Value Set: using ".signature">
