The problem is that if the above is in a function, when you list out the
function with "type funName", the \n has already been digested and
converted to a hard newline. This makes the listing look strange. I'd
rather see "\n".
I see what you mean:
$ test() { [[ "$f" =~ foo[^$'\n']*bar ]] && echo "foo bar" ; }
$ set | grep -A 4 '^test'
test ()
{
[[ "$f" =~ foo[^'
']*bar ]] && echo "foo bar"
}
Is there any way to get this?
Of course (and out of curiosity) I tried that display detail as well
in Kornshell to see how it behaves, and using a different command to
display it...
With my (old?) bash:
$ f() { [[ "$f" =~ foo[^$'\n']*bar ]] && echo "foo bar" ; }
$ typeset -f f
f ()
{
[[ "$f" =~ foo[^'
']*bar ]] && echo "foo bar"
}
The same with ksh:
$ f() { [[ "$f" =~ foo[^$'\n']*bar ]] && echo "foo bar" ; }
$ typeset -f f
f() { [[ "$f" =~ foo[^$'\n']*bar ]] && echo "foo bar" ; }
And for good measure also in zsh:
% f() { [[ "$f" =~ foo[^$'\n']*bar ]] && echo "foo bar" ; }
% typeset -f f
f () {
[[ "$f" =~ foo[^$'\n']*bar ]] && echo "foo bar"
}
Both seem to show "better aesthetics". Too bad it doesn't help for
your bash context.
