UNIX for Dummies Questions & Answers

Is the requirement to use sed for this a homework assignment requirement? If not, why are you insisting on using sed when awk is a MUCH better tool for this task?

In the future, do not go back and edit the problem that was initially posed. It confuses everyone who responded to your thread in the first ten hours after you posted it (before you changed what you said you wanted). And, it makes it hard for other people reading this thread to understand why the volunteers who responded to your original request made such stupid suggestions that do not produce output even close to what you now seem to want.

Code:

awk -F"=" '!($2 in A) {A[$2]; print "var" ++c "=" $2}' errorpath.csv

This is for the error=N format.

Heya, you could also try:

Code:

for num in $(tr -d [:alpha:] < errorPath.csv | tr -d [===])
do   echo $num
     ...
done

OR

Code:

for num in $(sed s,*=,,g errorPath.csv)
do  echo $num
    ....
done

Append -i to before the file in the sed call, if you want to modify the file and not just work with the generated output.
