Hello Vee!

There is an option for top to write a "snapshot" to file which you can subsequently use for filtering out this process:

top -f top.log

Kind regards,

We can do that but we only get the first page of top and not the remaining pages.

Hi

Refer to the ps -o options especially vsz for virtual stack size and pipe it into a UNIX95 command after you've selected the arguements from -o that you want.

UNIX95=1 ps -ef -o vsz,pcpu,ppid,pid,comm | sort -rn | top -10

Eact arguement represent a column of data but only the 1st argument is sorted in reverse order.

Hello Vee!

Use a large enough number with -n flag to get all your needed processes written to file:

top -f top.log -n

Kind regards,

Shalom,

UNIX95=1 ps -ef -o vsz,pcpu,ppid,pid,comm | sort -rn | top -10

The important part here is vsz, which stands for virtual size.

That based on this command syntax, which is not mine (I cut and pasted it) will give you the biggest reserver of swap first.
