This uses a /DIRECT port; it's a bit different,too, just to show
another way to do it. :)
foreach-line: func [
; I don't know if this REALLY uses less memory...
file: open/read/direct/lines file
code: func [line] code
while [line: pick file 1] [code line]
count-shell: func [shell [string! none!]] [
change shell: any [
find/tail shells shell
insert tail shells shell
] 1 + any [shell/1 0]
foreach-line %passwords.txt [
count-shell pick parse/all line ":" 7
foreach [shell count] sort/skip shells 2 [
; we really need FORMAT here!
head insert/dup count: form count " " 3 - length? count
any [shell "(none)"]
I don't have Perl here, so please repeat the tests with this to
see if it makes any difference.
