Unix KornShell - error message 'incomplete last line'

can I use the commend vi -r filename at this moment?

Binary1,  I have opened the file in vi, and saved it as you described, but it doesn't work in my case. All what i can see is the miscoded syntax which make no sense.

Try

dos2unix FileName

and retry.

dos2unix commend works for other file, not the one with issue. After does2unix the file, I opened the file in vi, nothing was changed. There are still the miscoded syntax full of screen

Is it a text file?

Let's review I had done before I got the error message:
1. I modfied few lines which located in bottom of the ksh file
2: I quit vi with :x
3.After a while, when I went back to vi editor, the error message appeared and asked me to hit Return to continue. I saw all original lines miscoded after I hit the enter key.

Then I find now where to modify the file any more.

no, it's an Unix executable file , name xxx_xxx.ksh

>>no, it's an Unix executable file , name xxx_xxx.ksh

It is still a textfile. Where did you get this file from?

Do

echo >> YourFileName

and open it again in vi.

my file was saved in a directory of Unix server, and it runs everyday normally

hi, I did echo, and vi file again. Here is the results as what I always saw:
// first line is my vi commend, then following line are return

Hmm, looks like the file is corrupt. I don't think you can recover it. I hope you have backup somewhere.

What does

cat -v archimedes_ftp_as.ksh

show?

my original syntax lines are part of followings:

if [ $pos3_ftptype == "MYMETRICS" ]; then
        {
        cd /eis01/ops
        ftp -ivn apsw8101 <<EOFSESSION
        user opsdb oracle
        binary
        cd feeds/inbound/mymetrics
        mput OpsCtrl_M_*
        mput ystr_psk.bat
        bye
EOFSESSION
cd /eis01/ops
rm -f OpsCtrl_M_*
}
fi

amit_g:
after cat -v filename, here are what syntax look like:
M-^P^V^WM-S^[^Y}M-(fM-^O#M-uM-iM-WlWvM-^KM-"M-hh<M-rLM-0M-xM-yM-bM-8zM-2M-^QyU:q

        ..............

I think the file crushed, when i cat to a new file, new file are with the miscoded syntax also

The file is corrupt. You have to get it from backup. It can't be repaired.

I have a two month ago back up file and modified in Notpad before. I tested it, error message is 'can not execute', any thougt. I did dos2Unix for the back up file

Notepad? Are you editing file in Windows and taking it back to Unix machine?

chmod +x fileName

yes, I editted a backup file two month ago, and then never use it till now

If you do cat -v backupfile and it shows correct code, the only thing missing could be execute permission. Do

chmod +x backupfilenae

and it should execute fine. You will have to do dos2unix again if cat -v shows control chars (^M).
