Echoing

I was just wondering how you would echo out different length variables but still have them all line up. I tried putting tabs between the variables but that didn't work as planned. For example this is in some loop, with different variables in it each time: echo "$1 $2 $3 $4 $5" Appears like...

SHOREWALL-TCPRI(5)						  [FIXME: manual]						SHOREWALL-TCPRI(5)

NAME

       tcpri - Shorewall file

SYNOPSIS

       /etc/shorewall/tcpri

DESCRIPTION

       This file is used to specify the priority of traffic for simple traffic shaping (TC_ENABLED=Simple in shorewall.conf[1](5)). The priority
       band of each packet is determined by the last entry that the packet matches. If a packet doesn't match any entry in this file, then its
       priority will be determined by its TOS field. The default mapping is as follows but can be changed by setting the TC_PRIOMAP option in
       shorewall.conf[1](5).

	   TOS	   Bits  Means			  Linux Priority    BAND
	   ------------------------------------------------------------
	   0x0	   0	 Normal Service 	  0 Best Effort     2
	   0x2	   1	 Minimize Monetary Cost   1 Filler	    3
	   0x4	   2	 Maximize Reliability	  0 Best Effort     2
	   0x6	   3	 mmc+mr 		  0 Best Effort     2
	   0x8	   4	 Maximize Throughput	  2 Bulk	    3
	   0xa	   5	 mmc+mt 		  2 Bulk	    3
	   0xc	   6	 mr+mt			  2 Bulk	    3
	   0xe	   7	 mmc+mr+mt		  2 Bulk	    3
	   0x10    8	 Minimize Delay 	  6 Interactive     1
	   0x12    9	 mmc+md 		  6 Interactive     1
	   0x14    10	 mr+md			  6 Interactive     1
	   0x16    11	 mmc+mr+md		  6 Interactive     1
	   0x18    12	 mt+md			  4 Int. Bulk	    2
	   0x1a    13	 mmc+mt+md		  4 Int. Bulk	    2
	   0x1c    14	 mr+mt+md		  4 Int. Bulk	    2
	   0x1e    15	 mmc+mr+mt+md		  4 Int. Bulk	    2

       The columns in the file are as follows.

       BAND - {1|2|3}
	   Classifies matching traffic as High Priority (1), Medium Priority (2) or Low Priority (3). For those interfaces listed in
	   shorewall-tcinterfaces[2](5), Priority 2 traffic will be deferred so long and there is Priority 1 traffic queued and Priority 3 traffic
	   will be deferred so long as there is Priority 1 or Priority 2 traffic to send.

       PROTO - protocol
	   Optional. The name or number of an IPv4 protocol.

       PORT(S) - port [,...]
	   Optional. May only be given if the the PROTO is TCP (6), UDP (17), DCCP (33), SCTP (132) or UDPLITE (136). A list of one or more port
	   numbers or service names from /etc/services. Port ranges of the form lowport:highport may also be included.

       ADDRESS - [address]
	   Optional. The IP or MAC address that the traffic originated from. MAC addresses must be given in Shorewall format. If this column
	   contains an address, then the PROTO, PORT(S) and INTERFACE column must be empty ("-").

       INTERFACE - [interface]
	   Optional. The logical name of an interface that traffic arrives from. If given, the PROTO, PORT(S) and ADDRESS columns must be empty
	   ("-").

	       Note
	       INTERFACE classification of packets occurs before classification by PROTO/PORT(S)/ADDRESS. So it is highly recommended to place
	       entries that specify INTERFACE at the top of the file so that the rule about last entry matches is preserved.

       HELPER - [helper]
	   Optional. Names a Netfiler protocol helper module such as ftp, sip, amanda, etc. A packet will match if it was accepted by the named
	   helper module. You can also append "-" and a port number to the helper module name (e.g., ftp-21) to specify the port number that the
	   original connection was made on.
