Overview
lsof lists information about files opened by processes. lsof provides information about:
- regular files
- directories
- block special files
- character special files
- executing text references
- libraries
- streams
- network files (Internet socket, NFS file or UNIX domain socket)
In absence of any options, lsof lists all open files by all processes.
To list open files by a specific process, use the process' PID as follows:
lsof -p <pid>
The output is similar to:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME java 10016 vagrant cwd DIR 252,2 4096 2621584 /home/test java 10016 vagrant rtd DIR 252,0 4096 2 / java 10016 vagrant txt REG 252,2 7734 2885001 /opt/java/x64/jre1.8.0_51/bin/java java 10016 vagrant mem REG 252,0 161704 1310723 /lib64/ld-2.12.so ...
