bash - immediately catching that not all environment variables have been defined on qsub command line -

-

I am using qsub to submit PBS jobs. 5 environment variables should be defined in my job file: qsub -v A = foo, B = bar, C = cat, D = dog, E = qux jobfile.sh . Occasionally, I can forget to define a variable on the command line when I submit it only to find out my error.

So, one way of catching this situation is that all the environment variables are not defined when submitting from qsub ? Or do I have to admit that I have to be very careful when depositing job files with very important environmental variables?

Thank you,

Paul

Best of you You can add a runtime check to the beginning of jobfile.sh to exclude if there are no expected variables set. 

  set -u: $ A $ B $ C $ D $ E set + U

set-u to shell Asks to exit if an unsetset parameter is attempted to increase : The command does nothing, but its debate first passes in standard detail, so if any of the five If not set, shell will exit. set + u then disables unset-parameter checks for the remainder of the balance.

qsub can not examine the given task to determine whether this variable is what it is.

c# - Highlight all words containing a letter in a richtextbox -

How do I highlight all the words in a letter in a rich text box? If I want to expose the words that contain the letters "a", such as a hat or candle word, both words are highlighted, I am using C # on Winform. Private Zero Button 208_Click (Object Sender, EventArgs E) {HighlightFrage (Rich Textbox 1, "A", Color. Yellow); } It exposes all the words with a word "a", but I'm not sure how to highlight the length of the spaces. Thank you. You can use the method to find incidents of sub-location. Then, use the property to change the colors back to Highlight colors for each event. int len ​​= richTextBox.TextLength; Int index = 0; String textconfind = "A"; // This will highlight the text you are viewing (index & lt; len) {richTextBox.Find (textToFind, index, len, RichTextBoxFinds.None); RichTextBox.SelectionBackColor = Color.Yellow; Index = rich textbox. Lesson Index (texttofind, index) + textaophind Langeline; } If you want...
