yes, it was a nasty one,
echo 'a'b'c'
abc
or more to the point
echo 'a a a' b b b 'c c c'
a a a b b b c c c

also thanks
qw is indeed the good solution,
---
but while I am on the air,
one more question,
this was part of a preprocessing script to change dates into a nicer
numerical format (quicker on large files than handling text in matlab)
inside the loop i had
s/(?<=X)(...)(?=X)/$t{\1}/e
but that doesn't work
it gives
SCALAR(0x105354f8)
after wasting too many minutes, i fell back on matlab,
but let me leave this open
how could i get this to work,
(or conversely what would you do to change 11-JUN-2011 to 11-6-2011 etc. )
