Shell Programming and Scripting

Hi guys, thanks a lot for your response. Let me tell you the complete requirement:
File 1:
111,10
112,20
113,30
114,40

File 2:
111,51,jklfsdfj
dkfld
111,52,dadfdl das
112,53,ewuei ewi ewop
wqopie ew
112,54,aaa aa[1] qq
113,55,ee ee[4] rr[6]
ew 1
ewe 4

My task is to produce the output as:
10 jklfsdfj dkfld dadfdl das
20 ewuei ewi ewop wqopie ew aaa aa[1] qq
30 ee ee[4] rr[6] ew 1 ewe 4
That is, whenever column1 of file1 matches with column1 of file2,
output has to be column2 of file1 and column3 of file2 corresponding to this match.
Hence I used join. Like this:
join -1 1 -2 1 -o 1.2 2.3 file1 file2 >file3
But the output is errorneous since file2 has data not in a pattern.

@ludwig : thank you. But i need the code in shell scripting.

Please show carriage-return and line-feed characters in the before and after examples. If you are dealing with a non-unix format text file it will require special techniques.

On MacOSs, the end-of-line character is \r, only.
Or this may be for some legacy app.
Stranger things have happened.

Hmm. I specialise in data conversion.
Unfortunately the O/P has not revealed the file format, the Operating System or any consistent data samples.
This thread is going nowhere fast.
