pmap Command Examples in Linux

The pmap command reports the amount of memory that one or more processes are using. For example, use this command to determine which processes on the server are being allocated memory and whether this amount of memory is a cause of memory bottlenecks:

# pmap -x [pid]

Example below shows the total amount of memory the cupsd process is using:

# pmap -x 1796
