Converting vertical items into Horizontal plz

Hi all im able to convert vertical into horizontal as follows using tr '\n' ','
to convert
4444 as to 1111,2222,3333,4444,

but im getting comma at end.. i want to remove the comma at end..

using sed we can do.... but it is limited to some numbers only...

can anybody give me the alternate solution so that it can apply for n no of numbers (ex 10000 numbers) and remove the comman at the end..

Thanks in advance

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Not sure if I got the problem; example with GNU sed:
> cat infile
$> sed -e :a -e '{N; s/\n/,/g; ta}' infile

One way of doing it with Perl:

$ cat f1
$ perl -ne 'chomp; push @x,$_; END {print join ",", @x; print "\n"}' f1

For some versions of paste, e.g.paste (GNU coreutils) 6.10:
paste -d, -s infile


I did *not* try it with thousands of lines ... cheers, drl

Edit 1:

This *did* work on 10,000 lines ... cheers, drl
