AIX平台查看最耗内存的N个进程

    AIX平台要查看最耗内存的进程可以用svmon命令，但此命令的输出看不出相关进程的命令全貌，为解决这个问题，写了个mtop()函数，在AIX5.2、5.3、6.1上测试通过：
mtop() {
svmon -Pt $1 | awk -v sq="'" -v dq='"' '
/^--/{a=1}
$1=="Vsid"{
  system("echo;ps alxww "pid"|awk -F: -v OFS=: "sq"length($0)>200{for(i=2;i<=NF;i++){gsub("dq" "dq","dq" )
  a=0
  }
a{print;if($1~/[1-9]/){pid=$1}}'
}

    又由于有些命令选项很多，尤其是java类的进程，CMD部分输出好几行，看着就眼晕，所以对这些长命令的CMD，特意将空格后自动补一个换行符。下面是AIX5.3上查看最耗内存的两个进程的例子：

    之前还写过几个版本的mtop()，一并贴出来：
mtop() {
svmon -Pt $1 | awk '
/^--/{a=1}
$1=="Vsid"{a=0}
a{print;if ($1~/[1-9]/){system("echo;ps eww "$1)}}'
}
mtop 2

mtop() {
svmon -Pt $1 | awk '
/^--/{a=1}
$1=="Vsid"{a=0}
a{print;if ($1~/[1-9]/){system("echo;ps alxww "$1)}}'
}
mtop 2

mtop() {
svmon -Pt $1 | awk -v sq="'" -v dq='"' '
/^--/{a=1}
$1=="Vsid"{a=0}
a{print;if ($1~/[1-9]/){system("echo;ps -elf | head -1;ps -elf|awk "sq"$4=="dq $1 dq sq)}}'
}
mtop 2

mtop() {
svmon -Pt $1 | awk -v sq="'" -v dq='"' '
/^--/{a=1}
$1=="Vsid"{a=0}
a{print
  if ($1~/[1-9]/){
  system("echo;ps alxww "$1"|awk -F: -v OFS=: "sq"length($0)>200{for(i=2;i<=NF;i++){gsub("dq" "dq","dq" )
  }
 }'
}
mtop 2
