How do I split a String in CSH?

Question

For example, I want to split \"one,two,three\" with comma as delimiter and use a loop to process the resulted three substring separately.

Answer 1

For example:

set s = "one,two,three"
set words = `echo $s:q | sed 's/,/ /g'`
foreach word ($words:q)
    echo $word:q
end

But consider whether csh is the right tool for whatever job you're doing:
