Column values are used to identify individual entries in tables using the format:
columname="value", \ columnname="value", ... |
Where:
columname is the name of a table column
value is the contents of a particular cell within a column. That value is what identifies a table row. (When using column=value to create or modify table data, always enclose the value element in quotes.)
For example, suppose you had a hosts table that listed machine names and IP addresses:
Table 14-2 Example Hosts Table
IP address |
name |
aliases |
---|---|---|
129.146.168.4 |
altair | |
129.146.168.119 |
deneb |
|
129.146.168.120 |
regulus |
dnsmaster |
129.146.168.121 |
regulus |
dnsmaster |
129.146.168.11 |
sirius |
In this example, your could identify the altair entry (row) in three different ways using the column=value of:
name=altair
address=129.146.168.4
name=altair,address=129.146.168.4.
But notice in the table above that the machine regulus is multi-homed and has two IP addresses. In that case, the column=value of host=regulus identifies two rows. To identify just the first regulus row, you would enter either:
address=129.146.168.120 or
address=129.146.168.120.,name=regulus,dnsmaster
Some nistbladm operations require that you enter a column=value pair for every column in the table.
