Shell Programming and Scripting

hi ,

When i ftp a text file from Windows to unix enviornment and open the file in " vi editor" the end line charcrter of the windows file is seen as "cntrl+M" charcter in the Unix enviornment.

Is there any command in unix , so that i dont see this "cntrl+M"
chararcter in the Unix vi editor.

Thanx,

"dos2unix"
and
"unix2dos" can be used to convert the files from dos to unix and vice versa using unix2dos

You can get it from web for free

Or even more simply, you transfer your text files in FTP ASCII mode.

hi,
in the Vi editor it still shows me the cntrl+M characters for the end- line ,
after using the dos2unix command ....
Is there any command by which the cntrl+M in vi editor can be made invisible........

Well there is one utility called flip (option -u to remove the ^M)

flip -u filename

that will remove the ^M, but I don' t know whether this is supported by all.

As for the dos2unix is concerned it will just put the output to the console, you can redirect it to some junk file or the same file.

dos2unix filename > junk.txt
mv junk.txt filename

Cheers

hi jaya,
My unix is solaris 5.8 , it doesnt support " flip " caoomand i guess . But its fine when i trasfer the file in
"ASCII" mode i get the file w/o cntrl+M characters ...
So the problem is solved...

Hi Dharmesh,

Still if you will ever find a file that contains the CTRL + m characters there is a very easy way to get rid of them. They have been mention many times here on the forums.

The way to do this is to open the file using vi. Stay in Escape mode and type the following :

:1,$s/<CTRL>+v <CTRL>+m//g

<ctrl>+v says that the next character is a special character. This will be substituted with nothing. i.o.w. removed
:1,$ just says from line number 1 until the end.
