ls

ls file_name

Description

Lists all configuration, policy, and if configured, core dump files in the system.

Syntax Description

file_name Lists all the files that match the wildcard.

Default

N/A.

Usage Guidelines

When you use issue this command without any options, the output displays all of the configuration and policy files stored on the switch.

When you configure and enable the switch to send core dump (debug) information to the internal memory, specify the internal memory location /usr/local/tmp to display the core dump files stored internally. For more information about core dump files, see Core Dump Files.

When you specify the file-name option, the output displays all of the files that fit the wildcard criteria.

Understanding the Output

Output from this command includes the following:
  • The first column displays the file permission using the following ten place holders:
    • The first place holder displays - for a file.
    • The next three place holders display r for read access and w for write access permission for the file owner.
    • The following three place holders display r for read access permission for members of the file owner‘s group.
    • The last three place holders display r for read access for every user that is not a member of the file owner‘s group.
  • The second column displays how many links the file has to other files or directories.
  • The third column displays the file owner.
  • The remaining columns display the file size, date and time the file was last modified, and the file name.

Core Dump Files

Core dump files have a .gz file extension. The file name format is: core.process-name.pid.gz where process-name indicates the name of the process that failed and pid is the numerical identifier of that process.

When the switch has not saved any debug files, no files appear. For information about configuring and sending core dump information to internal memory or a USB 2.0 storage device, see the configure debug core-dumps and save debug tracefiles memorycard commands.

For more detailed information about core dump files, see Troubleshooting section in the Switch Engine v33.1.1 User Guide .
