 .SH DESCRIPTION
 .SS "compress"

-.LP
 The \fBcompress\fR utility attempts to reduce the size of the named files by
 using adaptive Lempel-Ziv coding. Except when the output is to the standard
 output, each file is replaced by one with the extension \fB\&.Z\fR, while
 keeping the same ownership modes, change times and modification times, ACLs,
-and extended attributes. The compress utility also attempt to set the owner and
-group of \fIfile\fR\fB\&.z\fR to the owner and group of file, but does not fail
+and extended attributes. The compress utility also attempts to set the owner and
+group of \fIfile\fR\fB\&.Z\fR to the owner and group of file, but does not fail
 if this cannot be done. If appending the \fB\&.Z\fR to the file pathname would
 make the pathname exceed \fB1023\fR bytes, the command fails. If no files are
 specified, the standard input is compressed to the standard output.

 \fBpack\fR(1)) and it takes less time to compute. The \fIbits\fR parameter
 specified during compression is encoded within the compressed file, along with
 a magic number to ensure that neither decompression of random data nor
 recompression of compressed data is subsequently allowed.
 .SS "uncompress"

-.LP
 The \fBuncompress\fR utility restores files to their original state after they
 have been compressed using the \fBcompress\fR utility. If no files are
 specified, the standard input is uncompressed to the standard output.
 .sp
 .LP
 This utility supports the uncompressing of any files produced by
 \fBcompress\fR. For files produced by \fBcompress\fR on other systems,
 \fBuncompress\fR supports 9- to 16-bit compression (see \fB-b\fR).
 .SS "zcat"

-.LP
 The \fBzcat\fR utility writes to standard output the uncompressed form of files
 that have been compressed using \fBcompress\fR. It is the equivalent of
