Help me to read from both ziped and unziped files
Thanks, I read 'man gzcat'. But I did not find out if it will leave the rest of the files COMPRESSED or if it will DECOMPRESS them. Like I said, I want it to leave them COMPRESSED.

pppstats

pppstats(1M)						  System Administration Commands					      pppstats(1M)

NAME

       pppstats - print PPP statistics

SYNOPSIS

       pppstats [-a] [-v] [-r] [-z] [-c <count>] [-w <secs>] [interface]

DESCRIPTION

       The  pppstats utility reports PPP-related statistics at regular intervals for the specified PPP interface. If the interface is unspecified,
       pppstats defaults to sppp0. The display is split horizontally into input and output sections containing columns	of  statistics	describing
       the properties and volume of packets received and transmitted by the interface.

OPTIONS

       The pppstats options are:

       -a	       Display	absolute  values  rather than deltas. With this option, all reports show statistics for the time elapsed since the
		       link was initiated. Without this option, the second and subsequent reports show statistics for  the  time  since  the  last
		       report.

       -c count        Repeat  the  display  count  times.  If this option is not specified, the default repeat count is 1 if the -w option is not
		       specified, otherwise infinity.

       -r	       Display additional statistics summarizing the compression ratio achieved by the packet compression algorithm in use.

       -v	       Display additional statistics relating to the performance of the Van Jacobson TCP header compression algorithm.

       -w wait	       Pause  wait seconds between each display. If this option is not specified, the default interval is five seconds.

       -z	       Instead of the standard display, show statistics indicating the performance of the packet compression algorithm in use.

EXTENDED DESCRIPTION

       The following fields are printed on the input side when the -z option is not used:

       IN	       Total number of bytes received by this interface.

       PACK	       Total number of packets received by this interface.

       VJCOMP	       Number of header-compressed TCP packets received by this interface.

       VJUNC	       Number of header-uncompressed TCP packets received by this interface. Not reported when the -r option is specified.

       VJERR	       Number of corrupted or bogus header-compressed TCP packets received by this interface. Not reported when the -r	option	is
		       specified.

       VJTOSS	       Number  of  VJ  header-compressed  TCP  packets	dropped  on  reception by this interface because of preceding errors. Only
		       reported when the -v option is specified.

       NON-VJ	       Total number of non-TCP packets received by this interface. Only reported when the -v option is specified.

       RATIO	       Compression ratio achieved for received packets by the packet compression scheme in use, defined as the	uncompressed  size
		       divided by the compressed size. Only reported when the -r option is specified.

       UBYTE	       Total number of bytes received, after decompression of compressed packets. Only reported when the -r option is specified.

       The following fields are printed on the output side:

       OUT	       Total number of bytes transmitted from this interface.

       PACK	       Total number of packets transmitted from this interface.

       VJCOMP	       Number of TCP packets transmitted from this interface with VJ-compressed TCP headers.

       VJUNC	       Number  of TCP packets transmitted from this interface with VJ-uncompressed TCP headers. Not reported when the -r option is
		       specified.

       NON-VJ	       Total number of non-TCP packets transmitted from this interface. Not reported when the -r option is specified.

       VJSRCH	       Number of searches for the cached header entry for a VJ header compressed TCP packet. Only reported when the -v	option	is
		       specified.

       VJMISS	       Number  of  failed  searches  for  the cached header entry for a VJ header compressed TCP packet. Only reported when the -v
		       option is specified.

       RATIO	       Compression ratio achieved for transmitted packets by the packet compression scheme in use, defined as the size before com-
		       pression divided by the compressed size. Only reported when the -r option is specified.

       UBYTE	       Total  number  of  bytes to be transmitted before packet compression is applied. Only reported when the -r option is speci-
		       fied.

       When the -z option is specified, pppstats displays the following fields relating to the packet compression algorithm currently in  use.	If
       packet compression is not in use, these fields display zeroes. The fields displayed on the input side are:

       COMPRESSED BYTE	       Number of bytes of compressed packets received.

       COMPRESSED PACK	       Number of compressed packets received.

       INCOMPRESSIBLE BYTE     Number of bytes of incompressible packets (that is, those which were transmitted in uncompressed form) received.

       INCOMPRESSIBLE PACK     Number of incompressible packets received.

       COMP RATIO	       Recent  compression  ratio  for	incoming  packets, defined as the uncompressed size divided by the compressed size
			       (including both compressible and incompressible packets).

       The fields displayed on the output side are:

       COMPRESSED BYTE	       Number of bytes of compressed packets transmitted.

       COMPRESSED PACK	       Number of compressed packets transmitted.

       INCOMPRESSIBLE BYTE     Number of bytes of incompressible packets received; that is, those that were transmitted  by  the  peer	in  uncom-
			       pressed form.

       INCOMPRESSIBLE PACK     Number of incompressible packets transmitted.

       COMP RATIO	       Recent compression ratio for outgoing packets.
