MINIX 1.2 (640K) is being used to teach the OS course. We found a problem
with the 'tee' command. It doesn't function properly, if no appending to
an existing file is desired it overwrites the begining of the file.
$ echo one | tee jnk
one
$ echo two | tee -a jnk
two
$ echo three | tee -a jnk
three
$cat jnk
one
two
three
$ echo four | tee jnk
four
$ cat jnk
four
wo
three
We have fixed the problem, the cdiffs are given below for file
commands/tee.c. The file has to be recompiled and 'tee' should be
installed in /usr/bin.
