ifparse(1M)						  System Administration Commands					       ifparse(1M)

NAME
ifparse - parse ifconfig command line SYNOPSIS
/sbin/ifparse [-fs] addr_family commands DESCRIPTION
Use the ifparse command to parse the ifconfig(1M) command line options and output substrings, one per line, as appropriate. If no options are specified, ifparse returns the entire ifconfig command line as a series of substrings, one per line. OPTIONS
The ifparse command supports the following options: -f Lists only substrings of the ifconfig command line that are relevant to IP network multipath failover -s Lists only substrings of the ifconfig command line that are not relevant to IP network multipath failover OPERANDS
The ifparse command does not support the interface operand of the ifconfig command. EXAMPLES
Example 1 Parsing Command Line Options Relevant to Failover The following example shows the use of the ifparse command to parse the command line options relevant to IP network multipath failover: example# ifparse -f inet 1.2.3.4 up group one addif 1.2.3.5 -failover up set 1.2.3.4 up Example 2 Parsing Command Line Options That Are Not Relevant to Failover The following example shows the use of the ifparse command to parse the command line options that are not relevant to IP network multipath failover: example# ifparse -s inet 1.2.3.4 up group one addif 1.2.3.5 -failover up group one addif 1.2.3.5 -failover up Example 3 Parsing the Command Line For All Options The following example shows the use of the ifparse command to parse the command line for all ifconfig options: example# ifparse inet 1.2.3.4 up group one addif 1.2.3.5 -failover up group one set 1.2.3.4 up addif 1.2.3.5 -failover up ATTRIBUTES
