In this case, depending upon where you installed the Tutorial, the location of the meteorological files may have to be changed. Scripting will only be addressed indirectly in this tutorial to facilitate some of the examples and only a rudimentary knowledge of the commands is needed.
However, the advanced topics tutorial is entirely devoted to scripted examples. In this section, we will review the steps contained in the previous batch file that was used to run the concentration example. The first section sets the batch file execution parameters. The second section sets the value of script variables relating to file locations. The fifth section gives the command that actually runs the model. The sixth section creates the graphic label file and runs the concentration plotting program.
The seventh, and last section, displays the concentration graphic, and deletes the label file before closing. View best response. Products 68 Special Topics 41 Video Hub Most Active Hubs Microsoft Teams. Security, Compliance and Identity. Microsoft Edge Insider. Microsoft FastTrack. Microsoft Viva.

Question Close Reasons project - Introduction and Feedback. Should we burninate the [qa] tag? These determine which key is pressed by the user and then to act accordingly. I won't get into how these work because it is beyond the scope of this batch file example page. This is an improved version of the DELE. It allows multiple files of differing names to be specified for exclusion from deletion.
All else in the current directory will be deleted except for files with certain attributes. Next, an "IF" statement determines if you wish to show today's created or modified files from the current directory only, or those from the entire current drive. In either section, DIR is used to get a list of files. This is piped passed to the FIND command.
FIND looks for lines with today's date and displays them. Should the screen fill, the MORE command will present the list a screen at a time. Simply enter DRTD to get a list of files made or modified today in the current directory. You will have to change the path in the above batch file, if you decide to store it elsewhere.
Note, that the Reboot option should not be used if you are running any other program. Thus, be sure Windows, DOS SHELL, or any task switching program is shut down, and that you are not shelled out of any other application, before selecting the boot option of this batch file. This batch file requires one text file and two batch files to operate. The second batch file is created by the first, which is the one you'll run from the command line when you wish to return to the tagged directory.
This combination allows one to tag a directory so that one may return to it at any time, including after a reboot. It may also be included in any batch file that starts a program after which you wish to return to the directory from before you ran the program. An explanation follows "RT. Afterwards, are two improved versions, including an extremely simplified one. First, begin by creating or copying the following, beginning with the double colon lines:. Note that the " Space " above should not be typed.
Simply be sure there is a space after the "CD". Save this as "RT. Be aware that this file should be typed in a text editor that does not allow the cursor to drop below the last line. Otherwise, it will insert a carriage return and the batch file will not work. See if the cursor can be made to drop below this line by pressing the "Down Arrow" key. If it drops, expect that you may have a problem. TXT" at the command line. Be sure to include the space following "CD" and press "Control-Z" immediately after.
If you cannot get this to work by any method, e-mail me and I will send you a copy of the required text file. To use this batch file, when you are in a directory to which you wish to return, press "RT, Enter". The screen will clear and the message "Ready to Return to the Current Directory" appears. Now do whatever you want: Start and work within a program, do DOS work, even reboot.
When you wish to return to the tagged directory, enter "RTT". You'll be whisked back! It gets this information from "RT. Bat", even if "RTT. It answers "Yes" to the prompt regarding over-writing an existing file so you won't have to every time. The line then reads "CD tagged directory ".
Try it yourself at the command line. Since all this is placed into a batch file called "RTT. Plus, because it is written to the hard drive, it survives a reboot. Note this does not work if you tag a directory on one drive and attempt to to return to it from another drive. Simply switch to the tagged directory's drive first, then issue the "RTT" command. Now, I am one keystroke away from tagging a directory and only one away again from returning to it.
Also, to wow them further, I have all my batch files loaded on to a RAM drive. Since they are always in memory, they are zippy, zippy, zippy! See DOS Tips for more such improvements. I also have two other versions of this setup. They are more powerful, and the last is also much simplified.
Both allow one to return to the tagged directory from anywhere in DOS, regardless of the drive. Each is presented here:. The improved version requires two text files, two batch files and a utility to operate. As with the previous example, the second batch file is created by the first. This combination allows one to tag a directory so that it may be returned to at any time, still including after a reboot, but now from anywhere in DOS, even from another drive.
Simply be sure there is a space after the "CD" and that it is the last line of the file. As discussed farther back, this file should be typed in a text editor that does not allow the cursor to drop below the last line. Should this be a problem, see the previous version of the batch file for a test, and methods to overcome this. It does that by copying the lines in HOME. Finally, the batch file issues a "CD" command. However, here it's redirected to HOME.
When you run the HOME batch file, it changes to the drive and directory you had previously tagged. Neat, eh? Note that there are other ways of getting the current drive into a batch file, but this is a fast and reliable method.
It will also work in many versions of DOS, unlike some other methods. It too, should work on most versions of DOS. In the final version of this batch file, farther on, is another method that can also work well under various DOS versions. It tells DOS to overwrite without prompting. The "NUL" is used to keep the screen clean. Anything sent to NUL is not echoed displayed on the screen, so you don't see "One file s copied".
To use this batch file, when you are in a directory to which you wish to return, enter "Save-Dir". The screen will clear and the message "Ready to Return to Current Directory" appears. Now do whatever you want: Start and work within a program, do DOS work, switch drives, even reboot. When you wish to return to the tagged directory, enter "Home". You may also shell out of a program and use this to go to the tagged directory.
Then, typing "EXIT" takes you back into your application. In use, "Save-Dir" and "Home" are too long to type, so either shorten the names, or better yet, assign the batch files to a function keys. I use F11 and F As I like to be "Mr. Milliseconds", I am always looking for ways to shorten batch files in order to have them run faster and also to simplify them. This works by first creating HOME. If a previous version already exists, it is automatically overwritten.
Each variable's value is then sent as a separate line to HOME. To finish up HOME. Finally, the environment values are reset, thus removing them from memory. When Home. Consequently, you are logged on to the tagged drive and taken to the tagged directory. You may add the "DIR" switches you prefer to get say, an alphabetical list which pauses with each full screen, or whatever options you like.
Here is the link to get XSET. This is the same as the previous example. A prompt appears saying DOS is ready to return to that directory. This last version is the one I actually use, although with some modifications and additions to suit my particular computer setup. Here is an improvement on the SDEL. It allows one to specify as many files as the command line will hold.
This begins by checking to see if one or more file names were typed at the command line. Next it displays the directory name and shows up to the first nine files contained therein that are to be deleted. It then prompts the user to choose to delete the files or to abort the operation. As a final look, the directory is displayed to show the files are gone.
This batch file should be run in the directory containing the files you wish to delete. It may be run from outside, but it means typing the path for each file. That tedium aside, the final line would give a directory listing of your current directory and not that in which the deletions have taken place.
This will display a random "Thought of the Day" or any message you want seen upon bootup, as taken from a pool of messages. If not, change the path for it in the batch file. See Usage , below. DIR is then used to send a list of your message file names to XSET which selects one of the file names based on the random number it picked earlier. The chosen name is placed into an environmental variable called "FILE".
That in turn, is used by the MORE command to display the file's contents on a cleared screen. Just be sure the batch file refers to whatever directory you have created. Then, simply make a number of text files with whatever message you wish. Give them a ". To generate space around the message, have each file begin and end with some blank lines. Also, indent each message line a bit from both the left and right margins.
Now, your message will stand out on the screen. Suggested messages might be proverbs, sayings, jokes, or new words. With the latter, place the word on the screen with its definition. If learned words keep appearing on the screen, replace them with new ones.
Your vocabulary will increase with this idea. Another idea is to use this to learn to put names with images. These might be people, places or objects. Simply make up some. Instead of using MORE to display a text file, use an image viewer to put one of your selected images on the screen after bootup. Have you ever wanted to change to another drive's root directory but had forgotten you had been working on that drive earlier?
When you log on to it, you'll likely be in some sub directory. Here are two methods that will allow you to go immediately to the root directory of any drive on your system and see a files listing when you arrive. Afterward, a much simpler method to do the same thing will be shown. Be sure to place a space between the batch file name and the drive letter should you specify one.
Batch Script - CD, This batch command helps in making changes to a different directory, or displays the current directory. First off, the Windows path separator is \ but not /. Then you need to get aware that there is a current directory for every drive to fully. C:> CD Prog [PRESS TAB] Will go to C:\Program Files\ In a batch file to CD to the location of the batch script file (%0) C:\> CD /d "%~dp0".
