How to turn a file to a one liner thru sh script?
 

Good day to all!

Please help me. I wish to turn a file into a one liner using shell script.

For example, my file is below:

Is there a command in shell that would turn above file to this:

Thanks to all who would help. :)

Yes, you can use awk, sed or tr to do this.

If it's a *nix format text file (ie only \n as line terminator), then you can do:
The -s option will eliminate empty lines (which should otherwise give you ",," in the result).

tr<space>filename<space>'<space>','

But don't actually type <space>. Put in regular spaces.

Hi, I am trying tr right now. But it is taking a long time for the command to complete. :(
The file only has 37 lines... How would I know if it is working?

Can't sed be used? or awk maybe?

Sorry, the file should be given to stdin of tr, rather than being passed as a command line parameter.
Your running tr is probably waiting for some lines of input on stdin. Just use Ctrl-D (end of input character) to finish it.

still not working
 

Hi,

I have tried your suggestion. It now executes but the next line was not converted to "," Is it because tr executes only one line a time same as sed?

Thanks so much for helping out

i assume u may have to give the -g option right after -s like this

tr -s -g "\n" "," < your_file.txt

#or#

tr -sg "\n" "," < your_file.txt

There's no -g (or "global") option for tr as there is in sed. This "g" option is used in sed's tr or y transliteration operators.

The tr utility also works on all lines at once, not just the first one.
And my command does work for me (on a short example text file).

Have you checked if your text format is DOS-like (\n\r terminated) or *nix-like?
Maybe you should first run "dos2unix your_file" if it's in DOS text format.

tr '\n' ',' < filename.txt > filename1.txt

Here's the link of the file I am trying to turn into one line... I'm so desperate :(

cat "file.txt" | while read i; do echo -n "$i,"; done > newfile.txt

That command seems to work fine for me too.

Got It!
 

Hi all! Finally made it work!

Got the info from this site: http://ka1fsb.home.att.net/shfio.html

All I needed was $myData

I have learned something new. hehehehe
Thanks for all your help! :)

I would've told you that originally, except you said you needed this:
"36,dsf,sdf,dsfs" (With commas)

I am sorry to have confused you... My main goal was really to have the content of the file be in just one line (with or without the comma)

I prefer replacing \n with commas, however (for reasons that I do not know of) tr does not work in my code. I really dont understand why.

Anyways, thanks to all who had helped :)
