Append Command Results to an Existing File Use the -outa option when you want to append new command results to data stored in a previously written file. For example, at 11:00 A.M. you capture fan probe RPM readings for fan probe 0 on your system and write the results to a file called fans.txt. If you want to compare these results with output for the same probe obtained four hours later, you can use the -outa command to append the new output to fans.txt. Type: omreport chassis fans index=0 -outa fans.txt Fans.txt now reads as follows: Index Status Probe Name Reading Minimum Warning Threshold Maximum Warning Threshold Minimum Failure Threshold Maximum Failure Threshold : 0 : OK : System Board Fan 1 RPM : 2380RPM : 600RPM : 5700RPM : 500RPM : 6000RPM Index Status Probe Name Reading Minimum Warning Threshold Maximum Warning Threshold Minimum Failure Threshold Maximum Failure Threshold : 0 : OK : System Board Fan 1 RPM : 3001RPM : 700RPM : 5500RPM : 500RPM : 6000RPM You can use a text editor to insert the time that each block of data was captured. In comparing the two snapshots for fan probe 0, you can see that the second report shows several changes. The reading of fan RPM has increased by 621 RPM but is still within normal range. Someone has raised the minimum warning threshold by 200 RPM and has decreased the maximum warning threshold by 2000 RPM. Selecting a Format for Your CLI Command Output You can specify a format for your CLI command results. The format determines how the command output is displayed. If the command results are directed to a file, the format is captured by the file to which you write your command results. NOTE: The omconfig command ignores most output format options and returns plain text messages. However, if you use the xml option, the omconfig command returns XML code.
