UNIX for Advanced & Expert Users

It's not clear from your problem description what the issue is. It would help if you could post the exact error message you are getting.

Some things to try:

Post the output from the resulting script. Use code tags. Thanks.

So apart from the typo in the cp command name
I assume the above is the contents of file Test.SH
which you made executable (e.g. by chmod u+x Test.SH).
(Btw, why the extra copy of fileA.csv to fileB.csv beforehand?
Your Perl oneliner is called with the in-place-editing option -i
which will automatically dump a backup copy fileA.csv.bak for you)

But then you continue with
which makes no sense to me at all.
Of course, does the shell complain that the file doesn't exist.
Wasn't it ./Test.SH you wanted to execute?

no probs

If you could post the output of which perl and type perl and perhaps also locate perl those things might bring some clue.

As already mentioned you should find the path to your Perl interpreter (perl):

Code:

type perl

Then make a script with the following content (change the path to the Perl interpreter if the previous command indicates a different one):

Code:

#! /usr/bin/perl -i.bak -0777 -p

s/(".*?)[\r\n]*(.*?")/$1$2/g;

Run the script like this:

Code:

./your_script filename

For example:

Code:

./fix_broken_lines fileA
