Hi Axel, and thanks for your fast reply!
No, I really meant to ask how to _un_escape newlines, that is how to
achieve something like this in @#sh:
$ echo foo \
bar \
foobar
foo bar foobar
which in fish will issue:
[EMAIL PROTECTED] ~> echo foo \
bar \
foobar
foo
fish: Unknown command “bar”
fish: Unknown command “foobar”
Why do I want to achieve it?
Simply for a reason of readability, I prefer it to
echo foo bar foobar barf ...
Hope it is clearer my problem now (at least if it is worth the trouble...).
TIA, regards.
