Or shorter:

Code:
awk '$1 > c{print c FS $1-1}{c=$2+1} ' c=1 file

This don't give the expected output:

Code:
1 9
20 39
50 89

snmptable

SNMPTABLE(1)							     Net-SNMP							      SNMPTABLE(1)

NAME

       snmptable - obtain and print an SNMP table

SYNOPSIS

       snmptable [COMMON OPTIONS] TABLE-OID

DESCRIPTION

       snmptable  is  an  SNMP application that repeatedly uses the SNMP GETNEXT or GETBULK requests to query for information on a network entity.
       The parameter TABLE-OID must specify an SNMP table.

OPTIONS

       -Cb     Display only a brief heading. Any common prefix of the table field names will be deleted.

       -CB     Do not use GETBULK requests to retrieve data, only GETNEXT.

       -Cf STRING
	       The string STRING is used to separate table columns.  With this option, each table entry will be printed in compact form, just with
	       the  string  given  to  separate  the columns (useful if you want to import it into a database).  Otherwise it is printed in nicely
	       aligned columns.

       -Ch     Display only the column headings.

       -CH     Do not display the column headings.

       -Ci     This option prepends the index of the entry to all printed lines.

       -Cw WIDTH
	       Specifies the width of the lines when the table is printed.  If the lines will be longer, the table will be printed in sections	of
	       at most WIDTH characters.

       In addition to these options, snmptable takes the common options described in the snmpcmd(1) manual page.

EXAMPLES

       $ snmptable localhost public at.attable

       SNMP table: at.atTable

       atIfIndex   atPhysAddress   atNetAddress
	       1  8:0:20:20:0:ab 130.225.243.33

       $ snmptable localhost public -Cf + at.attable

       SNMP table: at.atTable

       atIfIndex+atPhysAddress+atNetAddress 1+8:0:20:20:0:ab+130.225.243.33

BUGS

       The  test  for  TABLE-OID  actually  specifying	a table is rather heuristic.  Note also that the test requires the defining MIB file to be
       loaded.
