[9fans] rc strings

[9fans] rc strings

[hugo rivera]

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.
