nv show system log file <file-name>

Shows the contents of a specific system log file. If the file is a regular log file (such as syslog.1), the system uses less so that you can scroll and search through the log entries. If the file is compressed (such as syslog.2.gz), the system displays the contents without decompressing the file. This command is useful for viewing both archived and compressed log files.
