UNIX for Dummies Questions & Answers

I developed the following in LINUX:

Code:

cat monica.txt | sed 's/;;;/\n;;;/g'>  fixed.txt
csplit -f comment -n 4 fixed.txt '/;;;/' {*}

Basically, I want it to take the file monica.txt and put every instance of ;;; on a new line and put it in fixed.txt, then split fixed.txt at every instance of ;;; and put it in new files called comment0001.txt, comment0002.txt,... comment2500.txt.

Now I have a Mac and am using UNIX in the program Terminal to do the task.

However, it is not creating a new line for every instance of ;;; (instead, it just replaces ;;; with n;;;. I also tried 's/;;;/\r;;;/g' because I think Mac handles line endings differently from Windows, but this didn't put every instance of ;;; on a new line, either.

I am also getting the error "*} bad repetition count" once it gets to 18 files, when it should generate 2500. Nowhere in the file do I have curly braces, so that isn't the problem.

I would appreciate any help!

I'm operating a Mac OS X with bin/bash.

Try this:

Code:

awk '
!c || /;;;/{c=sprintf("%04d",++i); close("comment" c ".txt")}
{print > "comment" c ".txt"}' monica.txt

I tried this and got:

awk: illegal statement at source line 3
context is
{print > "comment" >>> c <<< ".txt"}

Does anyone know what this means and how to fix this?

To me, I am getting no error but no splitting happens.

Here's my code.

Code:

echo "f1;f2;f3" | awk '/;/{c=sprintf("%02d",++i); close("out" c)} {print > "out" c}'

Code:

echo "f1;f2;f3" | awk -v i=0 '/;/{close("out"i); i++; next} {print > "out"i}'

Please let me know where I have gone wrong?

Try:

Code:

cat monica.txt | tr ';;;' '\n@@' | sed 's/@@/;;;/g'

Can you post your input file and the desired output?

They are attached now. Monica.txt is the full file, and comment0001.txt and comment0002.txt are samples of desired output.

I should also mention that I don't care if the ;;; is present in the output or not.
