Hi,
When catv gets no files on the command line (argv[0] == NULL after getopt),
after doing
its work it increments argv to point to the next argument, but since argv is
already
NULL, catv tries to open files whose names are the environment strings (e.g.
"HOME=/home/user", "PATH=...").
The fix/workaround below is to pre-decrement argv in this case, so that when it
is
incremented later it will be NULL and the loop will break.
