--如何查看单个进程在os层面的内存消耗 AIX: $ svmon -Pt10 | perl -e while(){print if($.==2||$!$s++);$.=0 if(/^-+$/)} ---- -用这个可以看最大的占用内存的10个进程 -------------------------------------------------------------------------------

AIX:
$ svmon -Pt10 | perl -e 'while(<>){print if($.==2||$&&&!$s++);$.=0 if(/^-+$/)}' ---- -用这个可以看最大的占用内存的10个进程

aix 下查看耗费内存最大的前10个进程
$ ps gv|sort -rn +6|head -10 --------------这个也是非常直观
