![]() ![]() May refer to each other that you need to manage for labs and projects. Manage a large number of files, not to mention more complicated designs which Inverter Schematic using Virtuoso a) Creating aĪll your designs are stored on the ECE UNIX network as various files andĪdditional files are required for Virtuoso and other tools to functionĬorrectly - even the inverter design in this tutorial will require you to close ther current terminal and open a new one. Use "gedit ~/.cshrc" open it, put those three 'source' command at the end of the file and save it. This file will be automatically executed every time you launch a terminal. Note: You can also put the above three 'source' commands into your shell configuration file, which is located in your user directory, and named '.cshrc'. If the setup is correct, you should see where Virtuoso You can validate the environment setup by: Source /import/scripts/synopsys2012.cshrc Window, use the following command to initialize the environment variables: You can start the terminal by right-clicking on the desktop and ![]() Logged into an ECE workstation or have established a VNC connection to an ECE Therefore, the first step is to bring up a Linux terminal, sometimes knownĪs a console, which allows you to input Linux command. Started from the command line as many environment variables should be assignedĬorrectly so Virtuoso can find various libraries and tools. There's an even simpler way to do this, though.Although the Virtuoso platform works under a UNIX/Linux GUI, it is usually You can use the history 5 command to make sure the command containing the password was removed from the history list. So, you can think of the second command as history -d "last command here." The history 1 command returns the previous command. The result of that execution posts as text in the original command. The portion of the command contained in the $() is executed in a subshell. $(history 1): This uses a command substitution.What we're going to delete comes is in the next portion of the command. history -d: In command two, we invoke the -d (delete) option of history. ![]() my-secret-password: The secret password we need to provide for the application on the command line.special-app: The name of the program we're using.This structure includes two commands separated with a semicolon ( ). It's a good investment of your time. There are far better ways to use the history command than just hitting the Up arrow repeatedly. However, if you learn how to use the history command, it can improve your use of the Linux command line, every single day. Like most Linux commands, there's more to it than you might think. The history command eliminates those issues. There are two types of errors: one that prevents the command from working, and one that allows the command to work, but makes it do something unexpected. The lengthier and more complicated a command is, the harder it is to remember and type without making an error. This isn't intended to just encourage laziness or save time-there's also an efficiency (and accuracy) factor at play. It allows you to review and repeat your previous commands. ![]() That's when the Linux history command comes in handy.

Unfortunately, on Linux, if you can't remember the past, you can't repeat it, even if you want to. ![]()
