Is there a small script I can add to an existing script to add CR LF at the end of every row, including the header row?

There are plenty of text manipulation tools such as awk, tr, and sed which can modify a file in the manner you describe. I would choose sed based on my stronger experience with it.

What is your experience with scripting, as well as any of these tools?

Have you attempted anything as yet?

The most common notations for control characters is to write them in octal, such as \015 and \012, when specifying them to the command to perform the modification.

I've done some scripting but not much. Don't know where or how to start

First I suggest a web search using the term, "append characters to the end of line using sed"

As common as I have used sed, I myself had to look it up.

I typically do search/replace versus add stuff. The hits I've seen though seem very reasonable and I've learned about the $ character for use in search-replace.

Next, suggest you consider reading the My Bash Blog link here, or same from my signature.

While I wrote that to help people debug bash scripts, please note that in the introduction for it I give links to the standard Bash scripting guides for basic and advanced, and I also make the comment that, "Whatever you can type on a command line, you can write in a script." The meaning there is that you can use sed, tr, or awk in the command line to try things out and then you can choose to put that command into a small script, if that is your choice. Noting also that using something like sed, the output typically goes to stdout, thus not modifying your file, and once you have the tuning of the command correct for your requirements, you can use the ">" Input-Ouput redirector to redirect stdout to a final result file where you have the added CR-LF as you wish it to be.

I seen something like this....

# sed 's/$/\r/g' file>newfile

but I don't know the functionality of it. I would be inserting code after the file has been moved.

In addition, adding CR,LF to the end of lines is basically converting a text file from Unix to DOS format. Searching on how to convert a text file from Unix to DOS format should provide some help.

As stated there are a few ways using tr, sed, awk, perl or the unix2dos script which is typically available in the repositories in most of the major distributions.

Please explain and what type of text file you trying to convert?

Instead of just going to output I would need the file modified

Why doesn't the file already have CR+LF endings? Is it a Linux file? If so, there are applications to convert the file if that is what you want to do.

Can you please give us some more background on what it is that you are doing. Context is king.

Well you should test it. This doesn't change your original file and you can try it several different ways.

You need to read about the sed command.

...and...
This seems to be a recurring theme; I'm sorry, but you've been asking about scripting for two years now. And this thread:
https://www.linuxquestions.org/quest...er-4175593953/

...from 2016 asks something nearly identical to this. Do you not know where to start after that long asking for/about scripts?

I apologize for not looking at my previous threads to prevent repeating questions. I'll try to do better.

I did try this but it only added CRLF on the first line:
[QUOTE]
sed -i 'ls/$/\r/' <filename>
[/QUOTE

I tried this....

sed -e 'ls/$/\r/' text*

but got an error

sed: -e expression #1, char 2: extra characters after command

Leave the -e out of that command.


Do not use wildcard characters for now.


Have you confirmed if these are Unix file types and that all you wish to do is convert them to DOS file types? If so, why aren't you considering the utility unix2dos?

To be honest with you, I'm not expecting trickydba to answer my question about this - he/she appears to have ignored my question and the previous comment on the same subject completely.

two ways:
unix2dos -- see the man page
(s)ftp ascii file transfer from a (l)unix 'puter to a windows 'puter.

Better yet, try this.
