How can I use sed to replace a ctrl character such as 'new line' (\0a) to something else? Or any other good command can do this job?
Thanks,

Hello!
I know that this expression gets rid of non-alphanumeric characters:
sed 's///g'
and I understand that it is replacing them with nothing - hence the '//'-, but I don't understand how it's doing it.
It seems it's finding strings that begin with alphanumeric and replacing them with... (2 Replies)

This seems like it should be an easy problem, but for some reason I am struggling with the solution.
I simply want to replace all characters after the first 3 characters with another character, preferably with sed.
Thanks in advance.

snapconv(1) Emulators snapconv(1)NAME
snapconv - Sinclair ZX Spectrum snapshot converter
SYNOPSIS
snapconv [ -c ] [ -n ] infile outfile
DESCRIPTION
snapconv converts between ZX Spectrum snapshot files.
OPTIONS -c specifies that all data in the output snapshot should be compressed, even if that compression will result in a bigger file than if
some data is left uncompressed. This helps compatibility with some buggy programs that can only read entirely compressed .z80 files.
-n specifies that the output snapshot should be uncompressed.
-f specifies that the A and F and A' and F' registers should be swapped. Version 0.5.0 and older of libspectrum(3) had a bug that
resulted in these registers being swapped in SZX snapshots only. Version 0.5.1 and newer of libspectrum(3) automatically recognise
these snapshots and correct the problem, but this flag is necessary to fix some snapshots created by development versions only of
libspectrum(3) which had the bug fixed, but cannot be distinguished from snapshots containing the bug.
infile specifies the snapshot to be converted. This file can be in any of the snapshot formats supported by libspectrum(3).
outfile
specifies the output snapshot. The format will be determined by the file extension and can be in any of the formats libspectrum(3)
supports for output.
BUGS
None known.
