1. Essential Skills: Using the Button Bar
-----------------------------------------------------

With the SecureCRT 6.7 beta release, the button bar has become still more capable and flexible, so now is a good time to cover the range of button bar capabilities.  In addition to supporting eight varied functions from shell commands to launching applications, the latest version of the button bar makes it easy to move buttons around a button bar or between button bars, and allows creating more than ten buttons on a single button bar.

Buttons on the button bar give you one-click access to frequently used SecureCRT menu commands and save thousands of keystrokes by avoiding manual command entry. A button command can be as simple as launching an external application like a text editor, or invoking a VBScript, or as complex as an easily mistyped shell command such as this example:

  chown -R `ls -dl . | awk -F\  '{print $3}'`:users .?* *\n

The following is a quick overview of button bar operations:

    • Enable the button bar from the View menu
    • To add or delete a new button or a button bar, right-click  on the button bar
    • With the 6.7 release, buttons can also be moved, copied, and pasted
    • Use the drop-down box to switch between button bars
    • Set the button bar location from the Global Options
    • To associate a button bar with one or more sessions (including the default session), edit the Terminal/Appearance/Window category of Session Options

You can find the complete updated button bar tip on the VanDyke Software website.

See also "The Button Bar" in the SecureCRT Help, in the section "Using the Software \ Getting to Know the Window".

2. Customize It: SecureCRT Keyword Highlighting
--------------------------------------------------------------------

SecureCRT 6.5 and later releases support real-time highlighting of user-specified keywords in the terminal window.  This is probably not the first application feature you would want to master, but it is invaluable for technical users who have to monitor host output for important alerts or events, often across many sessions.  Keyword highlighting might be used to call attention to errors in output from a script or program, or to flag specific text or IP addresses in a log file.

To set up highlighting, find the Highlight keywords group in the Terminal / Appearance category of the Session Options dialog.  You first select or create a list of keywords, with a choice to highlight them in reverse video or bold text.

Note that because keyword highlighting processes the remote session data stream in real time, it can affect display performance.  Thus, if the remote host supports keyword highlighting, we recommend you use that facility.

SecureCRT provides limited scripting access to keyword highlighting through the SessionConfiguration object.  Visit the VanDyke Software forums for a discussion of this, including example scripts.

3.
The SecureCRT Script Recorder and Python
---------------------------------------------------------------

The script recorder has been a part of SecureCRT for Windows since version 5.5.  Until recently the recorder was limited to generating VBScript code.  With the arrival of SecureCRT 6.7 in March, the recorder adds Python support, and is now available for Mac and Linux as well as Windows.

The script recorder can be used to automate issuing a series of commands that need to be performed regularly on one or more remote hosts.  The SecureCRT script recorder saves terminal keystrokes, so the entire set of commands can be captured and written to a script, making it easy to start writing scripts for SecureCRT even if you're not a Python or VBScript guru.

Use the Script menu to turn on recording, key in your commands and keystrokes, stop recording from the Script menu, and save the script as VBScript or Python code.  You can also use it as a foundation to build on to create more powerful scripts.

To start using scripting and the script recorder, look at the Scripting Essentials guide in the Support section at www.vandyke.com.  Chapter 1, Creating Scripts, covers using the script recorder to create a VBScript (Windows only).

Tip:  How to Install VShell Using VShell
--------------------------------------------------------

The VShell server now has the capability to launch remote exec commands in the background.  One of the benefits of this is that you can now upgrade the VShell installation without having to physically go to every machine that VShell is installed on.  In fact, many software packages can be distributed and installed in the same way; stay tuned for more on this in upcoming newsletters.

VShell 3.6.0 or later must be installed to use the ::bg remote exec flag that allows the remote execution process to run in the background.  This is required when upgrading the VShell installation because otherwise the remote exec connection will terminate during the upgrade and cause an incomplete installation.

With the right version of VShell in place, you first use vcp to upload the installer to the remote system, as in this example:

   C:\>vcp vshell-ftps-x86.3.8.0.132.exe username@hostname:.

The next step is to remotely execute the installer, specifying the flags that allow the installation to run without interaction (/s /v"/qn"), and the ::bg flag.  The following example shows
the syntax:

  C:\>vsh username@hostname bg::"vshell-ftps-x86.3.8.0.132.exe /s /v"/qn""

The installer defaults are used when the installation is run silently.  If you require a different installation directory, or other non-default parameters, an answer file is needed. To learn more about silent installation and answer files, visit this tip.
