I need to delete ^M symbol at the end of the each line, but vi interpretes ^M as one symbol and when I type ^M in my substitution construction I can only type it as two symbols ^ and M, so pattern doesnt match. Thats the problem.

Hi Igor,

To delete ^M, you can use the following,

# strings

# sed 's(ctrl v ctrl m)g//g' old.file > new.file

Hi,

In additioto to dos2unix in vi:

In order to insert ctrl-character use:
CTRL-V CTRL-CHTR.
I your case :
vi file,
:%s/CTRL-VCTRL-M$//
:wq

And the reason you have a file with this strange character is that you transferred a file from a PC to HP-UX. Because PCs have very different file formats, you need to transfer these text files with ftp's special translation feature called ASCII. And this is required to send HP-UX text files to a PC -- always use the ASCII option.

But for all current files on your HP-UX system, don't bother with vi or sed, just use the two special commands that perform the translation: dos2ux and ux2dos
