At first, it's better to use ed (or `ex' in line mode) instead of a screen
oriented editor like vi within a shell script. And secondly, the vi provides
with ^V (Ctrl-V) to escape other control character.
Good luck,

Hi!
Try using ^V (CTRL-V) to escape ESC. Simplified: Press ^V ESC in
Edit Mode.

Use ^V to add the esc - you will see a ^ , which will turn into ^[
when you hit the esc key, and vi will treat it as a single character.

Why not use ed instead of vi?
Something like:
#!/bin/sh
touch file
ed - file << END
r !date

You can use dd to cut the file into two pieces, use echo to create a
temporary file with a null character in it, then cat the three files
back together, e.g.:
ssd3450_root> hd testit

ssd3450_root> echo "\000" >temp1
ssd3450_root> dd if=temp1 of=temp2 bs=1 count=1

1+0 records out
ssd3450_root> hd temp2
0000 00 .
0001
ssd3450_root> cat test1 temp2 test2 >> testout
ssd3450_root> hd testout
0000 74 65 73 74 20 64 61 74 61 20 30 31 32 33 34 00 test data 01234.
0010 35 36 37 38 39 30 20 54 45 53 54 20 44 41 54 41 567890 TEST DATA
0020
I had to use dd to cut the line feed off of the end of the temp1 file
because my /usr/ucb/echo -n does not seem to do octal output correctly.
I know this is kludge-y, but it works. There may be a better way.

Sure, one method in vi (sorry) command (or movement, whatever) mode, enter

You may want to substitue "/^> /" (notice space after >) for the string to
be substituted. If I recall there is a space after the > in reply mail.
Otherwise the result will be indented one space.
Hope it helps...jc

You're going about it the hard way:
g,/usr/support/yard/,s,,/usr/support/common/progs/,g
or perhaps:
%s,/usr/support/yard/,/usr/support/common/progs/,g
Yes, \/ is one approach that works, but it is often easier
to just use a different delimiter.

It's extremely standard, and probably predates Unix. I wouldn't use '.',
though, since it would make it difficult to use '.' as a metacharacter in
the pattern. I usually use ',', since it has no special meaning in regular
expressions, and it can be typed without shifting.

PFE (Programmer's File Editor) for Windows is quite happy with
newline only files. It doesn't convert them to CR-LF
automatically, but will if that is what you want. The price?
Free. Excellent value.
