Java How to concat line first and then removing the ^M character
hi

Someone can give me some clue or script in writing the below requirement

I am having 5 or 10 files of unix files which contain ^M charactes.

First we have to find ^M character and concat the line where it has broken and then we have to remove the ^M character from the uxix files.

Thanks

I know the answer for removing the ^M ie..

awk '{ sub("\r$", ""); print }' filenew > newfilename which works for me .

First we have to search ^M and then concat the line and then remove . I am not able to find concat ideas.

Thanks

concat
Code:
cat file1 file2 file3 file4..... > filenew
awk '{ sub("\r$", ""); print }' filenew > newfilename

or

Code:
cat file1 file2 file3 file4..... > filenew
dos2ux filenew > newfilename

In one file it has some lines like this

CDMA 1x=5102305, 2008-09-05 07:59:04, NAI=$QCMIPNAI^M
0000000000@vzw3g.com, MIN=0000007356, Config=62558-11 Verizon Std P3

Here first we have to make it in one line and then remove the ^M .

For me dos2unix is not working in Linux.

Thanks

Hi,
if it's a question of first removing RETURN, maybe pushing it through tr -d "\r" could help?

/Lakris

PS or tr "\r" " " and take it from there?

Try this:

Code:
sed '/^M$/N;s/^M\n//' file

To get the ^M character type <CTRL>-v and <CTRL>-m successively.
