Browsing the File System in Backup Boot Mode
Browsing the File System in Backup Boot Mode
The PXM45 hard disk stores log files, configuration files, and boot and runtime software. The switch
operating system supports a set of UNIX-like commands that you can use to locate log files or manage
software updates. Many of the commands are the same commands that operate at the switch prompt,
however, in backup boot mode you must enclose the file path in quotation marks. Table B-1 lists
commands that you can use to browse the file system.
Note File and directory names in the switch file system are case sensitive.
Table B-1 File System Commands at Backup Boot Prompt
Command Description
cd Change directories.
Syntax: cd “<path>”
Example: cd “C:FW”
copy Copies a file from one location to another.
Syntax: copy “<source file name>”, “<destination file name>”
Example: copy “C:FW/pxm45_002.001.000.000_bt.fw”, “C:FW/test”
remove Deletes a file.
Syntax: remove “<file name>”
Example: remove “test”
ll List directory contents using long format, which includes the name, size, modification
date, and modification time for each file. This command also displays the total disk
space and free disk space.
Syntax: ll [“path”]
Example: ll “C:FW”
Note When you first start a session in backup boot mode, the present working
directory is a directory on a remote server as specified by the runtime software
bootchange command. If you enter the ll command and the remote server is
unavailable or does not exist, the switch appears to hang as the switch attempts
to access the remote server. To avoid this, select a directory on the C: drive with
the cd command first or specify a path with the ll command. To reboot the
PXM45 card when it is searching for a remote server, press Control-X.
ls List directory contents using the short format, which displays filenames, total disk
space, and free disk space.
Syntax: ls [“path”]
Example: ls
