Your Project
Make a web site that shows plots that YOU generated!
Plots should regenerate every hour!
![Page 3: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/3.jpg)
Step 1: Decide what plots you want to show
Pick out a couple of charts that can be made with the programs we have written this semester.
Don’t go nuts—maybe 4 or 5 plots at most!
![Page 4: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/4.jpg)
Step 2: Make special versions of your programs with NO interaction!
Your programs shouldn’t require anyone to choose a variable, domain, contour interval or anything like that.
Each program should produce ONE chart!
![Page 5: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/5.jpg)
Step 3: Modify these programs so that they produce an XWD file
XWD = “XWindow Dump” a file format for images, similar to GIF
We’ll learn how to do this later.
![Page 6: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/6.jpg)
Step 4: Create a “script” that runs these programs.
“scripts” – little programs that perform unix commands.
We’ll learn more about this later.
![Page 7: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/7.jpg)
Step 5: Set up a “crontab” that runs your script each hour
crontabs are scripts that execute on a schedule.
We’ll learn more about this later.
![Page 8: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/8.jpg)
Step 6: Make an HTML page to display your output
You already know how to do this!
![Page 9: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/9.jpg)
The Steps:
1. Decide what you’ll show
2. Versions w/o interaction
3. Produce XWD files
4. Set up scripts
5. Set up crontabs
6. Write HTML code
![Page 10: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/10.jpg)
Step 3: Produce XWD files of your maps
/export/home/schragej/X/xwdjms a special version of a standard unix program “xwd” captures a graphics window and saves it as a .xwd
file no beeping!
xwdjms –name myplot
![Page 11: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/11.jpg)
Step 3: Produce XWD files of your maps
/export/home/schragej/X/xwdjms a special version of a standard unix program “xwd” captures a graphics window and saves it as a .xwd
file no beeping!
xwdjms –name myplot
The name of the graphics window that you opened!
Don’t use any spaces!
![Page 12: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/12.jpg)
Step 3: Produce XWD files of your maps
xwdjms uses “printf” to dump everything it does to the screen.
You need to “capture” this to a file!
xwdjms –name myplot > image.xwd
![Page 13: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/13.jpg)
Step 3: Produce XWD files of your maps
xwdjms is a UNIX command, not a C command!
system(“ ”);
![Page 14: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/14.jpg)
Step 3: Produce XWD files of your maps
xwdjms is a UNIX command, not a C command!
system(“ ”);
Example: system(“rm *.dat”);
![Page 15: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/15.jpg)
Step 3: Produce XWD files of your maps
system(“/export/home/schragej/X/xwdjms –name myplot > image.xwd”);
![Page 16: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/16.jpg)
Step 3: Produce XWD files of your maps
system(“/export/home/schragej/X/xwdjms –name myplot > image.xwd”);
Also, turn off the ghold!!!!!!!!
![Page 17: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/17.jpg)
Step 3: Produce XWD files of your maps
system(“/export/home/schragej/X/xwdjms –name myplot > image.xwd”);
Also, turn off the ghold!!!!!!!!
Still more problems…
![Page 18: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/18.jpg)
Step 3: Produce XWD files of your maps
Draw the mapDraw the datasystem(“xwdjms…”);
Even though you’ve given the orders to draw all the lines and all the data, the graphics might not “keep up”…
![Page 19: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/19.jpg)
Step 3: Produce XWD files of your maps
Draw the mapDraw the datasystem(“xwdjms…”);
…when you call xwdjms, it’s possible/likely that the picture isn’t done yet!
You’ll capture a partial image!
![Page 20: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/20.jpg)
Step 3: Produce XWD files of your maps
Draw the mapDraw the dataXFlush(display);system(“xwdjms…”);
You need to XFlush the display.
![Page 21: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/21.jpg)
Step 3: Produce XWD files of your maps
Draw the mapDraw the dataXFlush(display);system(“xwdjms…”);
You need to XFlush the display.
![Page 22: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/22.jpg)
Step 3: Produce XWD files of your maps
Draw the mapDraw the dataXFlush(display);system(“xwdjms…”);
Display *display;display = gget_xdisplay();
![Page 23: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/23.jpg)
Step 3: Produce XWD files of your maps

![Page 24: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/24.jpg)
The Steps:
1. Decide what you’ll show
2. Versions w/o interaction
3. Produce XWD files
4. Set up scripts
5. Set up crontabs
6. Write HTML code
![Page 25: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/25.jpg)
Step 4: Create a “script” that runs these programs.
“scripts” – little programs that perform unix commands.
An example of a script:
![Page 26: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/26.jpg)
Step 4: Create a “script” that runs these programs.
An example of a script:
#! /bin/csh –f
rm *.gif
mv sample.data my.data
![Page 27: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/27.jpg)
Step 4: Create a “script” that runs these programs.
All scripts start with “pound bang space slash bin slash sea ess aich space minus eff”
#! /bin/csh –f
rm *.gif
mv sample.data my.data
![Page 28: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/28.jpg)
Step 4: Create a “script” that runs these programs.
Everything after that just runs as if you typed it at the keyboard in Unix.
#! /bin/csh –f
rm *.gif
mv sample.data my.data
![Page 29: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/29.jpg)
Step 4: Create a “script” that runs these programs.
Everything after that just runs as if you typed it at the keyboard in Unix.
#! /bin/csh –f
setenv DISPLAY wx-sun1:0.
rm *.xwd
MakeTempContours
/opt/sfw/bin/convert image.xwd temperature.gif
mv temperature.gif public_html

Step 4: Create a “script” that runs these programs.
Change the execution privileges on your script:
chmod a+x MyScript
Test it.

The Steps:
1. Decide what you’ll show
2. Versions w/o interaction
3. Produce XWD files
4. Set up scripts
5. Set up crontabs
6. Write HTML code
![Page 32: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/32.jpg)
Step 5: Set up a “crontab” that runs your script each hour
crontabs are scripts that execute on a schedule.
To edit a crontab, you need to have set the EDITOR variable to your favorite editor:
setenv EDITOR vi setenv EDITOR pico
![Page 33: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/33.jpg)
Step 5: Set up a “crontab” that runs your script each hour
start editing:crontab –e
Every line of the crontab schedules one task to be run repeatedly.
There are 6 entries on every line:
![Page 34: Building Your Web Site ATS 315. Your Project Make a web site that shows plots that YOU generated! Plots should regenerate every hour!](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f0e5503460f94c228e2/html5/thumbnails/34.jpg)
Step 5: Set up a “crontab” that runs your script each hour
The first entry is the MINUTE of each hour during which to run your job.

Step 5: Set up a “crontab” that runs your script each hour
Entries 2, 3, 4, and 5 are the hour, day, day of week and day of month on which to run the job.
A star means “every”.

Step 5: Set up a “crontab” that runs your script each hour
The sixth entry is the name of your script, with the full path name!
If your script prints ANYTHING to the screen, you’ll need to include:
> /dev/null
or the output will be emailed to you!
