so, if you're using a hash like I think you might be:
s = <output of ps command>
h = {}
s.each_line do |line|
_, pid, _, cmd = *(line.match /(\d+)\s.*(:\d+){2}\s(.*?)$/)
h[pid] = cmd
end
I think that should work.

cmd = string[/\s(\S+)$/, 1]
doesnt fetch me anything:)
program=string.split.last
what if
string = "root 14051 14033 3 08:39 pts/2 00:00:00 /bin/bash -x
-s"
it fetches only -s for me.
sec, last = string.split.values_at(1, -1)
doesnt work for the same reason
i need everything after 00.00.00 till the end
i.e., /bin/bash -x -s
program=string[/[a-z\/]+$/]
the command column mauy start with character. i dont want to limit it in
my regexp. it has to be generic.
with all your comments, i tried
pid = run_process[/\s(\d+)/, 1]
cmd = run_process[/:\d+:\d+\s(\S.*)\s$/, 1]
On Behalf Of Divya Badrinath:
# string = "root 14051 14033 3 08:39 pts/2 00:00:00 /bin/bash -x -s"
# it fetches only -s for me.
# sec, last = string.split.values_at(1, -1)
# doesnt work for the same reason
# i need everything after 00.00.00 till the end
# i.e., /bin/bash -x -s
you can modify the non-regex solutions since they are just plain array manipulations
cmd = string[/\s(\S+)$/, 1]
doesnt fetch me anything:)
No idea that was not my code
program=string.split.last
what if
string = "root 14051 14033 3 08:39 pts/2 00:00:00 /bin/bash -x
-s"
it fetches only -s for me.
As simple as possible, but not simpler. Now we are in the simpler case
But see below
program=string[/[a-z\/]+$/]
the command column mauy start with character. i dont want to limit it in
my regexp. it has to be generic.
with all your comments, i tried
pid = run_process[/\s(\d+)/, 1]
cmd = run_process[/:\d+:\d+\s(\S.*)\s$/, 1]
Does not work the :\d+ stuff might be a parameter of the program
is there any other way?
Yep counting fields after all
x = split
y= x[1]
z = x[7..-1].join(" ")
There might still be a pitfall though in case of some old processes
where you will have to analyse if the date takes one or two fields if
memory serves.

What is your terminal width, 30?
oops wrong thread, I was caught in the "Beautiful Code Thread".
Sorry
