These are the errors I get when attempting to run the code and I still do not understand what parameters need to be sent with ./<filename> to get the programs to execute. I'm sorry if these seem like really dumb, basic issues, I have very little experience with Unix.

prog2: I understand that there are three parameters that need to be passed($1, $2p, $3), but I don't know what they are. I assume one is a file name and another is a command, but I am not sure what the third is.

Code:

[gaben:CS307]$ ./prog2
sed: -e expression #1, char 1: unknown command: `,'

prog3: There are syntax errors in the code, but I have the code identical to the handout.

Code:

[gaben:CS307]$ ./prog3
./prog3: line 2: syntax error near unexpected token `('
./prog3: line 2: `set pwrs=(00000000)'

prog4: And prog4 simply prints out several blank lines and then an actual line of code, rather than executing.

Code:

[gaben:CS307]$ ./prog4


if ( $#argv==0 ) then
 if: Badly formed number.
