Re: delete space

$ perl -we '
print "--$_--\n" for grep  $_, split /[ ,]+/, " c1, c2, s1, s2, c3 ";
'
--c1--
--c2--
--s1--
--s2--
--c3--

Split on [ ,]+ so that split eats the spaces as well as the commas. The grep eliminates the first empty ("") element.

That will cause "`c1, c2a c2b, c3`" to return four elements instead of three. `split /, /` [download] or `split /\s,\s/` [download] is more appropriate.	[reply] [d/l] [select]
