ipcs - calculate the memory used by a user hiding in shared memory
Description
Traditional UNIX tools like topas, top or nmon won't show the memory consumed by a process if the memory is in a shared segment, to calculate the memory consumed in MB in shared memory by a user:
# ipcs -m -a | awk '/user/ {i+=$10} END { print i/1024/1024 }'
Example
ipcs -m -a | awk '/db2q510/ {i+=$10} END { print i/1024/1024 }'
