Thanks to Bill that he add a very good additional solution
He also hint me that I have to be aware of which numbers I mean, e.g. 12 is the line feed and 14 is the form feed (in octal!!!), in dec is 12 the form feed and 14 shift out ;-).

Use tr, it's much faster and simpler:
tr -c "\014" "\040" < some_data_file > new_data_file
014 is the CTRL-L or formfeed character (see man ascii)
I used \040 to change the formfeed to a space. Just replace
040 with whatever character you want from the ASCII chart.
ALWAYS use a leading zero to specify an octal string as shown
in the man page for ascii.
Thanks again to all.

Hi again,
Thanks a lot who has responed:
For the actual script I will use the ^v^L (ctrl v and ctrl L) solution. In future I will using sed or ed to get more speed.
Here the suggestions: ################################################################################################
Note that ^M is your guide, ^ (that is ^ and a space) is an ascii-readable view to value 0. ^A is for 1, ^B is for 2, ^L is for 12 and so on.
If you know the <ctrl>v followed by a non-readable ascii code, you most likely once accidently hit <ctrl>vv and view at the prompt, it shows ^V !!
THere you have it, to get ^L, just type <ctrl>v<ctrl>l. (and so you can also get ^M with <ctrl>v<ctrl>m)....
The origin is the other way round: ^V is shorthand for <ctrl>v.
Thanks to Corné, Harm and Cooper (excuse me when I am using the last name, I dunno it better ;-))
################################################################################################
If you've got Perl installed, you can do this from the command line:
$ perl -pi -e 's/\014//g' myfile
Thanks to Christopher ################################################################################################
sed -e 's/Ctrl-V Cr//g' -e 's/Ctrl-V Ctrl-L//g' File > file.out Thanks to Jack, Brett, Stuart
Original question:
Hi folks,
I have a data stream and have to replace the form feed (^L; ASCII 12) with another symbol. My script looks like:
vi xxx <<EOF1
:%s/^M//g # I know I have to press ctrl+v in insert mode
# and than the carrage return key to get the ^M
:%s/^L//g # ,but how can I get the ^L ???
:wq!
EOF1
Thanks in advance for advice.
Klaus
