I want to do this:
cat myFile | sed -e "s/[ ]*CTRL-M/\n/g" > myFileCleaned
where Ctrl-M is character 0x013 and \n is a newline.
I have a file that has many, many, many long lines, each with many sets
of data, each set being separated by many spaces, each instance of which
is ended by character 0x013, kinda like:
data ^Mdata ^Mdata ^Mdata ^Mdata ^M
but the spaces before the ^M are about 77 in number (seems to be
consistent), and the data strings are longer, containing several
elements, each separated by either one, two, or three spaces. If I can
match on any number of spaces ("[ ]*") which are immediately followed by
0x013 (^M) and replace each instance with a newline, I'll be set (almost
certainly).
I think I recall \n being the equivalent of a newline, although I may be
confusing things with my brief venture into perl.
I did man regexp, but didn't find what I wanted. I'm not sure where
else to look.
I'm sure that vim could probably do it, but I have already found that
trying to search for specific things in that complexity is like looking
for a tiny stainless steel needle in a humongous haystack. Magnets
won't do me any good.
I have already had dealings with sed and regexp, and figured this would
be a good opportunity to pick up a new trick.
TIA
