I was not aware that I was using two different shells, although I will admit that I was in was in the wrong shell, which I did not realize until you mentioned this. My instructor told us to use tcsh which I switched to and I am still only able to get one program to execute, but I am getting slightly different errors now.

prog2 I attempted to pass with parameters

Code:

gaben:~/CS307> ./prog2 1,4d Zidane
sed: -e expression #1, char 5: extra characters after command

I know sed in an editing command and I assumed that $1,$2 were references to the lines to be edited, p is the command that will be editing those lines, and $3 is the name of the file being modified. I also attempted:

Code:

gaben:~/CS307> ./prog2 a,cd Zidane

Because I know $ means variable substitution, but this just returns a new line.

prog3 now gives me

Code:

@pwrs[1]=1: No match.
@next=2: Command not found.
next: Undefined variable.

which I assume is due to a lack of parameters.

prog4 is giving the exact same output as before.

My code is written exactly as it is in post #1, I even copied pasted it directly from the vi editor, so the spacing and new lines are all exactly the same from the post as in the actual code.

Is --xtrace (-x) something that I input on the command line, and since it is an argument, what is the command that gets passed with it? Is this something that I can find using man, and if so, in what section?


I tried to be more specific this time and tried to include everything I thought would be necessary. If there is anything else, let me know, but I am completely stuck.
