Re: [tlug] sed or awk or what?

[Bruno Raoult <br@example.com>]

Or shorter:

sed -e '2s/\(.* \)\{8\}[^ ]*/\170' < A.txt

But I did not test on other systems than mine (linux):
I am always afraid when I use these kind of regexp
with sed, I had some bad experiences at work :-(

I am not sure this works on Solaris/AIX/MacOS X (yes,
the new one we can include in Unix tests!) and others. 

One example: some sed versions will need a "/" at the
end of the substitute command: It would be better to
add it in all cases.
