- randstr is a simple utility that implements the minimal functionality of
- the fortune program. Give it the name of a strfile text or data
- (pointer) file, and it will randomly select and print one text string.
-
- It isn't intended to do a lot; it's supposed to be a sample
- implementation of a minimal strfile type random text retrieval function,
- such as might be used to generate random .signature files.
-
- For example:
-
- Create a file of signatures in strfile format (none more than four lines
- long, please!). Call it signatures, for ease of understanding.
-
- Run it through strfile to create the pointer file; put both files in a
- safe place--your home directory, for instance.
-
- In your .login or .profile, add the line:
- randstr $HOME/signatures >.signature
-
- Each time you log in, your signature will change randomly to one of those
- in the file signatures. If you change the file, be sure to update the
- pointers file! (use strfile)
-
- If you happen to have root privileges, you might be able to hack Pnews
- to change the sig randomly whenever you post. The solution is left as
- an exercise for the student (gee, I *always* wanted to say that!).
-
- Another example:
-
- As root, create a shell or Perl script to read /etc/passwd and create
- a strfile text file containing login name (line one) and GECOS (line
- two).
-
- Add an entry to crontab.root that runs that script once a month, then
- uses strfile to create the data file, and randstr to select one entry
- at random.
-
- Give valuable prizes to the winning login. The script can also auto-mail
- to the user, with Cc: root.
-
- Any other 'lottery'-style function could be implemented the same way.
-
- Both of these examples are more easily implemented with randstr (which
- doesn't care where the files are, and accepts no parameters) than with
- fortune, which expects files to be in a place specified at compile-time.
