pmap: command not found

pmap is a command-line utility in Linux/Unix systems that reports the memory mapping of a process or processes. It displays the memory usage of a process in a detailed and comprehensive manner. This can be useful for analyzing the memory usage of a process, identifying memory leaks, and optimizing memory usage.

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
1796:   /usr/sbin/cupsd
