3.7.1

The log-name parameter is an optional parameter. When this parameter is not specified, a listing of all available log files is displayed. In addition, you can provide a partial or complete log file name (as shown in the show log output) in the log-name parameter.

3.6.1

The log-name is a required parameter.

3.5.1

This command was introduced.

Usage Guidelines

In Release 3.6.1 and earlier releases, the exact directory path (/var/log) and exact filename is required to run this command.

Starting with Release 3.7.1, this command is modified for the following:

  • Display a list of all available log files (using show log).

  • Display a list of log files that match the partial filename provided in the log-name parameter.

  • Display the content of the specified log file if the filename matches exactly as shown in show log output.

To filter the content of a log file, you can use the show log log-name | ? command.

Examples

The following example displays the available log files. 


nfvis# show log
