  1. why doest lab 8 work?

  2. Please give an example of why it doesn’t work… i.e. explain what part of it you are having problems…

  3. There was a typo in lab #8 indicating pressing <ctrl><c>
    It has now been fixed… Perhaps that was the problem you were referring to in lab #8…

  4. i lol’d at “why doesnt lab 8 work…

    i lol’d again at the fact that doesnt was not spelled correctly.

    • LOL. And you didn’t spell doesn’t correctly either. There is an apostrophe sign between n and t. Sorry but you are wrong too. 🙂

  5. i accidentally removed my assignment 2! doing rm -r, is there a way I can undo this or recycle bin or something

    • If you did via an SSH session (i.e. from the shell prompt – no).
      You would have to request ASC to restore your file from backup.
      You would have to e-mail help@acs.senecac.on.ca

      This usually take 2-3 days…

  6. I rm *’d my assignment 3 by mistake as well.

    I figured doing it all over again will make me super smart now though.

  7. I rmed my assignment as well. Not by accident, but because the bloody thing does not work. My friend told me to error check a number I was supposed to check if the variable divided by itself would equate to zero, but the implementation is rather difficult. I am going to start from scratch and do everything with awk this time.

    • Oops, I meant variable/variable eq 1 and not zero.

    • I think your friend led you astray.
      That is way too complex. I have demonstrated how to do this in class many times. It goes back to the lesson in testing – there are two ways to test!
      This is easy, not difficult!!!! That’s about all I will say about that!!!

  8. I can’t submit lab 11 I get this message:

    You must create directory pathname “~/l1b11” first,
    change to that directory and complete this lab…

    so I made that directory and got the same message.

  9. I only managed to find 9 errors on the exam. Fail 😦

    • I assume that you are talking about the last question – I hope you don’t mean you found 9 typos of the final exam!

      There was one at the very beginning that was very subtle – there are 10 distinct errors. I’m looking at the 10 bugs as I’m typing this 🙂
      Good luck on the other exams 🙂

  10. Mr Saul , for assignmet2 winter 2010. In the sample run while recording the payments,you have provided the script “the transaction no” i was wondering if it is “Invoice number” rather because it doesnt make any difference.The payment goes towards vendor anyways which has a unique Invoice number.Any comments please!!

  11. Here is the error message I got for lab11:
    You must create directory pathname “~/l1b11” first,
    change to that directory and complete this lab…

    Check the location and spelling of your directory,
    and run submission program again…
    kliu39@matrix:~/l1b11>

    The working directory should be l1b11 or Lab11? Confused. My current directory is Lab11, then I renamed it with l1b11, but both failed with same error message

    • Professor, I already figured that out. I examined your lab check bash file and found that the working directory should be “lab11”. However, according to your lab instruction, the working directory is “Lab11”, and from the error message, the working directory is “l1b11”. Maybe we need update the lab instruction and the error message for failed submit. Thanks a lot.

  12. Hey Murray,
    So I was in your class last semester (Now working at co-op). I have to do a lot of scripting here and your ppt’s have been awesome! I’m taking a look at the awk examples right now 🙂

    Cheers,

    • Good to hear you are learning what I taught you.

      I had some of my students see your posting to confirm that OPS435 course is indeed important! 🙂

  13. Hey Murray
    I have a question about the OPS435 assignment2.. will you be executing the bash file (makePayments.bash) within the asn2 directory ? or will it be done through another directory ?
    Cause I have created the bash file where it creates/deletes the temporary files within my asn2 directory
    Thanks

  15. Hi Murray
    I’m currently working on my OPS435 assignment 1, however I cannot recall the command for displaying the current users first / last name etc. As well, for our bash script would you prefer the code to be separated with comments to explain the processes, or just have comments at the beginning of the bash script.

    Also, to change the error message to a value other than 0, I simply put || exit >2 Or is there more information that must be added, in order to write to said error.

    Thanks

    • I have mentioned that method to get the first and last name in class many, many times. it is in the lab (lab #2 as I recall) and it was on quiz #1 question ! I recommend to read the notes and labs…. Commenting to explain shell script is go where ever in the script…

  16. I am unable to find an answer for online tutorial review question. Is there was way I can skip a question?

    • Actually, they are shell scripts, so you can open another shell, open the shell script in an editor, go to the bottom, move upwards are get the answers.
      At least this gets students to learn to read a shell script, and then they don’t get stuck. I already mentioned that in class…

  17. hi murray, how’s it goin? i just wanna ask something about a good programming language to start with. On my very own i am just new to programming and it is kind of hard for me especially i dont have any experience when it comes to computer languages.Thank you and have a nice day.

    • Bash shell scripting is a good place to start, then if you are curious, I would try C programming (which has syntax similar to JavaScript and Perl), then if you are keen, perhaps C++, and Python. Point here is to be flexible and adaptable to quickly learning languages, but general programming approaches are solid… although subtle differences in syntax, etc…

  18. I have a question that has nothing to do with this course. I am thinking to broadcast internet radio live. Do you know any free source that i can use or can you give me any tips.
