Add return feed.

Jack Daniels_1 — Fri, 09 Aug 2002 13:49:13 GMT

Hello!

I get these files from NT world. When i open them with vi, i get the message "Incomplete Last line". Also each line has ^M characters except the last line. I am tryin to use sed to strip the ^M characters (cat $file | sed 's/^V^M//g' > $file.new) but this deletes the last line too.
So i am trying to figure out some way to add a return feed to just the last line before running the sed part.

I assume this will retain the last line after running the sed part.

Any help is greatly appreciated.
TIA.

Check out the dos2ux command.

try
dos2ux filename > filename.ux
similarly
ux2dos filename.ux > filename.winders

Later,

The dos2ux command will do this for you. Man dos2ux.

Plan B. If you are transferring these files via FTP, use the ascii command prior to the put or get and the conversion will be automatic.

Hi Jack

Coupe of ways to do it

dos2ux filename > newfileanem

will get rid of the ^M

also

cat filename | sed -e "1,$s/\^M//g" should do the trick

Nearly same question, but same solution applies :

cat | tr -d "\r" >

MANOY, not that I begrudge you points, but what does your answer add to mine? more than 10 minutes later. I guess you would have read the thread before you post.

THanks to everyone for the immediate response. (yes, i need to go back and give points.)

To go back to the problem...
Oops, My mistake!(So full marks to everyone) I forgot to mention that i have already tried the dos2unix option. It removes the ^M fine but the subsequent job which uses the file fails.

So i manually added a return to the end of the last line and it works fine.

So it appears that i need to find a way to get a return feed at the end of the last line only.

Any help??
TIA.

I have attached a sample file.

remove the ^M from the last line only:

# perl -pe 'BEGIN{$/=undef}s/\r\Z//' infile >outfile

Hi
If you want to add a linefeed only to the last line this is the same as appending a linefeed to the file.
echo '\n' >>filename.
