Tom Rhodes 33ffdd8115 Don't truncate the output file before making sure that we can ... read at least 1 byte from the input file without problems. This fixes a bug in uncompress(1) that causes the accidental removal of files that happen to have the same name as the output file, even when the uncompression fails and is aborted, i.e.: $ echo hello world > hello $ touch hello.Z $ ls -l hello* -rw-rw-r-- 1 giorgos giorgos 12 Jun 14 13:33 hello -rw-rw-r-- 1 giorgos giorgos 0 Jun 14 13:33 hello.Z $ ./uncompress -f hello uncompress: hello.Z: Inappropriate file type or format $ ls -l hello* -rw-rw-r-- 1 giorgos giorgos 0 Jun 14 13:33 hello.Z $ PR: 46787 Submitted by: keramida		2003-06-14 13:41:31 +00:00
