end of line issue
Hello,

I am getting few text files with no EOF ( or end-of-line ) which i need to fix using a command so that i can include it in a script. Now i'm fixing this issue by opening the file in "vi" editor and adding last line.

e.g.,

server1#wc -l temp.txt
9 temp.txt
server1#cat temp.txt
0830200422
0830200459
0830200462
0830200548
0830200716
0830200765
0830200809
0830200831
0830200836
0830200942server1#

This file actually has 10 numbers but showing as 9 lines and also notice prompt displayed at the end of last line.

Please suggest how to fix this? i guess "tr" would do here.


Thanks
Prvn

EOF is determined by the filesystem. In DOS ASCII 26 serves as an EOF marker for MS-DOS text files. Not Unix.

Anyway, if "server" should always be alone on the last line try this
Code:
awk ' {  p=index($0, "server")
           if(p>2)
           { print substr($0,1,p-1)
              print substr($0, p)
            }
            else {
                print $0
            } 
        } '  inputfile > tmp.tmp
  mv tm.tmp inputfile

Thanks for your reply Jim,

I'm not sure if i made myself clear on explaining the problem.

Problem is not with "server" prompt etc.(it's just an indication that prompt coming on the same line of the last one of the file)

Yes, the file received from a DOS/Windows System and is seen as only 9-lines by UNIX. That's the problem. I need to fix it so that ALL 10 lines can be read by UNIX system.


Thanks

Hammer & Screwdriver Can you give us the exact characters?
Perhaps
cat myfile | od -An -t dC -w10

This will create a 10-across representation of everything in the file, with the ASCII codes for the characters.

awk strips carriage control then adds it by default in the print statement.
Assuming you don't have ^M (DOS carriage return char):
Code:
awk '1' inputfile > outputfile

adds carriage return to the last line... is that what you mean?

Thanks Jim, Your solution worked great.

Thank joeyg - Your solution did not work and gave syntax errors.

usage: od [-bcCdDfFoOsSvxX] [-] [file] [offset_string]
od [-bcCdDfFoOsSvxX] [-t type_string]... [-A address_base] [-j skip] [-N count] [-] [file...]

   49   32   10

With the above example, I can see the 10 representing line-feed characters. And that is what I expect to see between lines, and at the very end.

Not sure what went wrong with your try. Perhaps cut/paste my string onto your system. Or, I am running bash on Solaris; maybe an issue or difference with your system.
