Memory usage by process

The Solaris pmap command will provide the total memory usage of each process.

The following shell script prints the memory usage of each process, sorted by ascending memory usage.

#!/bin/sh

/usr/bin/printf "%-6s %-9s %s\n" "PID" "Total" "Command"
/usr/bin/printf "%-6s %-9s %s\n" "---" "-----" "-------"

for PID in `/usr/bin/ps -e | /usr/bin/awk '$1 ~ /[0-9]+/ { print $1 }'`
do
   CMD=`/usr/bin/ps -o comm -p $PID | /usr/bin/tail -1`
   # Avoid "pmap: cannot examine 0: system process"-type errors
   # by redirecting STDERR to /dev/null
   TOTAL=`/usr/bin/pmap $PID 2>/dev/null | /usr/bin/tail -1 | \
/usr/bin/awk '{ print $2 }'`
   [ -n "$TOTAL" ] && /usr/bin/printf "%-6s %-9s %s\n" "$PID" "$TOTAL" "$CMD"
done | /usr/bin/sort -n -k2

Example output:
