  • Unix Login Profile
    Unix login Profile A general discussion of shell processes, shell scripts, shell functions and aliases is a natural lead in for examining the characteristics of the login profile. The term “shell” is used to describe the command interpreter that a user runs to interact with the Unix operating system. When you login, a shell process is initiated for you, called your login shell. There are a number of "standard" command interpreters available on most Unix systems. On the UNF system, the default command interpreter is the Korn shell which is determined by the user’s entry in the /etc/passwd file. From within the login environment, the user can run Unix commands, which are just predefined processes, most of which are within the system directory named /usr/bin. A shell script is just a file of commands, normally executed at startup for a shell process that was spawned to run the script. The contents of this file can just be ordinary commands as would be entered at the command prompt, but all standard command interpreters also support a scripting language to provide control flow and other capabilities analogous to those of high level languages. A shell function is like a shell script in its use of commands and the scripting language, but it is maintained in the active shell, rather than in a file. The typically used definition syntax is: <function-name> () { <commands> } It is important to remember that a shell function only applies within the shell in which it is defined (not its children). Functions are usually defined within a shell script, but may also be entered directly at the command prompt.

  • ROM Monitor Commands, Page 54-2
    CHAPTER 54 ROM Monitor This appendix describes the Cisco Catalyst 4500 switch ROM monitor (also called the bootloader program). The ROM monitor firmware runs when the switch is powered up or reset. The firmware helps to initialize the hardware and boot the operating system software. Use the ROM monitor to perform certain configuration tasks, such as recovering a lost password, booting an IOS image on the on-board flash/removeable storage media/management port, and upgrading the Rommon image itself. If there is no Cisco IOS software image loaded on the switch, the ROM monitor runs the switch. This appendix contains the following sections: • Entering the ROM Monitor, page 54-1 • ROM Monitor Commands, page 54-2 • Command Descriptions, page 54-2 • Configuration Register, page 54-3 • Exiting the ROM Monitor, page 54-5 • Digital Signing, page 54-6 Note For complete syntax and usage information for the switch commands used in this chapter, refer to the Catalyst 4500 Series Switch Cisco IOS Command Reference and related publications at this location: http://www.cisco.com/en/US/products/ps6350/index.html Entering the ROM Monitor To use the ROM monitor, you must be using a terminal or PC that is connected to the switch over the console port. Refer to the installation chapter in the Cisco Catalyst 4500 Switch Hardware Installation Guide that came with the switch to connect the router to a PC or terminal.. Perform these steps to configure the switch to boot up in ROM monitor mode the next time it is rebooted. Command Task Step 1 enable Enters privileged EXEC mode.
