Roger,
those are good answers, but to go a step further and actually get the
command output into an array so you can manipulate it - here is an
example in unix:
(it sorts and formats the du output so i can see which subdirs are using
the most space)
parse arg directory . -- directory name can be passed as
argument
If directory = '' Then -- no directory name passed?
directory = '.'
"du" directory "| rxqueue" -- pipe du stdout to rexx queue
duline = .array~new(queued()) -- set up du lines array
i = 1
Do queued() - 1 -- queued() returns # of lines in
external data queue
Parse Pull size subdir . -- get a line
duline[i] = RIGHT(size,9,' ') subdir -- right-align size so sort works
i += 1 -- increment array index
end
duline~sort -- sort the array
Do item over duline -- send sorted array to stdout
say item
End
exit
sample output:
...
56 /home/prgramly/euler
88 /home/prgramly/Expect-1.20/tutorial
184 /home/prgramly/IO-Tty-1.07
352 /home/prgramly/expect
432 /home/prgramly/Expect-1.20
13120 /home/prgramly/temp
it obvious that i have something(s) big in my temp/
