Hi,
% n=`{echo 'a b'}
sets n to a list containing two elements, 'a' and 'b'. How can I set n
to a single string 'a b'? note that I must execute external
commands, so the obvious solution
% n='a b'
doesn't work for me.
Saludos,

No, because the number of spaces in between is important. But I found a solution
% ifs='
' n=`{echo 'a b'}
works fine. Sorry for the noise.

what about this?
ifs='
' n=`{echo 'a b'}
or
ifs='' n=`{echo 'a b'}
if you don't mind the newline character being in the string.

Yes, works just as I needed.
Thanks.
