Shalom,

1) You have made a mistake with ascii/binary in your ftp transfer. The windows ftp client defaults to ascii which probably caused this.
2) dos2unix normally fixes this problem, but you may also have to do the download/uplaod over again properly.

hi all

try first transfer file in binary mode.

you can try 'dos2ux > >file_good' too

the old way:
tr -d "\015" file.out

Here is the tested and proved method to take away the ^M from any file.


# To take off the control chars from a file
# vi fn

Then Esc column and do the foloowing >

:%s/^M/ ( ie, control v control m) and enter .

This will take away the control Chracters.

If its a small file, you can even do # cat filename > newname

using vi:

To remove the characters use the command sequence
:1,$s/^V^M//
followed by a return.
Note: Please be aware that the ^V will not echo on your screen,
but ^M will.

Here's a link on handling characters with sed:

http://www-h.eng.cam.ac.uk/help/tpl/unix/sed.html


# IN UNIX ENVIRONMENT: convert DOS newlines (CR/LF) to Unix format
sed 's/.$//' # assumes that all lines end with CR/LF
sed 's/^M$//' # in bash/tcsh, press Ctrl-V then Ctrl-M
sed 's/\x0D$//' # gsed 3.02.80, but top script is easier

HI:

# perl -pe 's%\r\n%\n%; s%\032%% if eof' file

...mimics the HP-UX 'dos2ux' command including handling the 'sub' character (^Z) that marks the end of a DOS file.

To update your file(s) inplace and keep a backup copy as '.old', do:

# perl -pi.old -e 's%\r\n%\n%; s%\032%% if eof' file

Regards!

Thanks steven for correction.
I have uploaded in binary mode, it'll be in ascii mode.

Thanks everyone for your great support.

One thing about using sed to remove the control-M. It is possible for files to sometimes have text but no lines. I had an EDI file like this. If this is the case, the sed command will not remove the control-M because it never had a complete line to work on.
