这是我的一句话:

cat /proc/*/status | grep -E 'VmSwap:|Name:' | grep VmSwap -B1 | cut -d':' -f2 | grep -v '\-\-' | grep -o -E '[a-zA-Z0-9]+.*$' | cut -d' ' -f1 | xargs -n2 echo | sort -k2 -n

这一行的步骤是:

Get all the data in /proc/process/status for all processes Select the fields VmSwap and Name for each Remove the processes that don't have the VmSwap field Remove the names of the fields (VmSwap: and Name:) Remove lines with -- that were added by the previous step Remove the spaces at the start of the lines Remove the second part of each process name and " kB" after the swap usage number Take name and number (process name and swap usage) and put them in one line, one after the other Sort the lines by the swap usage

不完全清楚您的意思是要找到交换出最多页的进程还是导致交换出最多页的进程。

对于前者，您可以运行top并按swap排序(按'Op')，对于后者，您可以运行vmstat并查找'so'的非零条目。

在MacOSX上，你也可以运行top命令，但需要输入“o”，然后输入“vsize”，然后输入ENTER。

运行top，然后按OpEnter。现在进程应该根据它们的交换使用情况进行排序。

这是一个更新，因为我原来的答案没有提供一个确切的答案，在评论中指出的问题。从htop常见问题:

It is not possible to get the exact size of used swap space of a process. Top fakes this information by making SWAP = VIRT - RES, but that is not a good metric, because other stuff such as video memory counts on VIRT as well (for example: top says my X process is using 81M of swap, but it also reports my system as a whole is using only 2M of swap. Therefore, I will not add a similar Swap column to htop because I don't know a reliable way to get this information (actually, I don't think it's possible to get an exact number, because of shared pages).

这是脚本的另一个变体，但意味着提供更可读的输出(你需要以根用户身份运行这个脚本才能得到准确的结果):

#!/bin/bash

SCRIPT_NAME=`basename $0`;
SORT="kb";                 # {pid|kB|name} as first parameter, [default: kb]
[ "$1" != "" ] && { SORT="$1"; }

[ ! -x `which mktemp` ] && { echo "ERROR: mktemp is not available!"; exit; }

[ ! -d "${TMP}" ] && { echo "ERROR: unable to create temp dir!"; exit; }

SUM=0;
OVERALL=0;
    echo "${OVERALL}" > ${TMP}/${SCRIPT_NAME}.overal;

for DIR in `find /proc/ -maxdepth 1 -type d -regex "^/proc/[0-9]+"`;
do
    PID=`echo $DIR | cut -d / -f 3`
    PROGNAME=`ps -p $PID -o comm --no-headers`

    for SWAP in `grep Swap $DIR/smaps 2>/dev/null| awk '{ print $2 }'`
    do
        let SUM=$SUM+$SWAP
    done

    if (( $SUM > 0 ));
    then
        echo -n ".";
        echo -e "${PID}\t${SUM}\t${PROGNAME}" >> ${TMP}/${SCRIPT_NAME}.pid;
        echo -e "${SUM}\t${PID}\t${PROGNAME}" >> ${TMP}/${SCRIPT_NAME}.kb;
        echo -e "${PROGNAME}\t${SUM}\t${PID}" >> ${TMP}/${SCRIPT_NAME}.name;
    fi
    let OVERALL=$OVERALL+$SUM
    SUM=0
done
echo "${OVERALL}" > ${TMP}/${SCRIPT_NAME}.overal;
echo;
echo "Overall swap used: ${OVERALL} kB";
echo "========================================";
case "${SORT}" in
    name )
        echo -e "name\tkB\tpid";
        echo "========================================";
        cat ${TMP}/${SCRIPT_NAME}.name|sort -r;
        ;;

    kb )
        echo -e "kB\tpid\tname";
        echo "========================================";
        cat ${TMP}/${SCRIPT_NAME}.kb|sort -rh;
        ;;

    pid | * )
        echo -e "pid\tkB\tname";
        echo "========================================";
        cat ${TMP}/${SCRIPT_NAME}.pid|sort -rh;
        ;;
esac
rm -fR "${TMP}/";

我使用这个，如果你只有/proc，没有其他有用的。只需要设置nr为你想看到的顶部交换器的数量，它会告诉你进程名，交换占用空间(MB)，它是ps -ef的完整进程线:

Nr =10;对于pid在$(对于文件在/proc//状态;do awk '/ vmswwap |Name|^Pid/{printf $2 "" $3}END{print ""}' $file;做|分类3 - n - r - k - $ {nr} | |头awk{打印$ 2});做awk ' / VmSwap |名称| ^ Pid / {printf 2”、“3美元}{打印”“}”结束/proc/$ Pid /状态| awk的{打印1美元”“2”“3/1024美元“m”}”| sed - e ' s /。[0 - 9]/ / g’;ps ef | awk“2美元= = $ Pid{打印}”,回声;完成
