Release	Modification
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
