svn但是没有按照内存排序，然后查了下，按一下shift
+
f
就可以出现排序的列Current
Sort
Field:
N
for
window
1:DefSelect
sort
field
via
field
letter,
type
any
other
key
to
return
a:
PID
=
Process
Id
shown
e
to
screen
width
or
your
b:
PPID
=
Parent
Process
Pid
field
order,
the
'<'
and
'>'
keys
c:
RUSER
=
Real
user
name
will
be
unavailable
until
a
field
d:
UID
=
User
Id
within
viewable
range
is
chosen.
e:
USER
=
User
Name
f:
GROUP
=
Group
Name
Note2:
g:
TTY
=
Controlling
Tty
Field
sorting
uses
internal
values,
h:
PR
=
Priority
not
those
in
column
display.
Thus,
i:
NI
=
Nice
value
the
TTY
&
WCHAN
fields
will
violate
j:
P
=
Last
used
cpu
(SMP)
strict
ASCII
collating
sequence.
k:
%CPU
=
CPU
usage
(shame
on
you
if
WCHAN
is
chosen)
l:
TIME
=
CPU
Time
m:
TIME+
=
CPU
Time,
hundredths*
N:
%MEM
=
Memory
usage
(RES)
o:
VIRT
=
Virtual
Image
(kb)
p:
SWAP
=
Swapped
size
(kb)
q:
RES
=
Resident
size
(kb)
r:
CODE
=
Code
size
(kb)
s:
DATA
=
Data+Stack
size
(kb)
t:
SHR
=
Shared
Mem
size
(kb)
u:
nFLT
=
Page
Fault
count
v:
nDRT
=
Dirty
Pages
count
w:
S
=
Process
Status
x:
COMMAND
=
Command
name/line
y:
WCHAN
=
Sleeping
in
Function
z:
Flags
=
Task
Flags
<sched.h>然后就可以选择自己喜欢的排序方式啦，例如选择N，看看那几个进程占用的内存大，接下来就可以分析啦PID
USER
PR
NI
VIRT
RES
