Open file descriptor, kernel lock & socket inspector for Linux
Process Handle Inspector is a desktop open file descriptor, kernel file lock, and socket endpoint viewer for Linux system administration and application debugging. An independent Linux alternative inspired by command-line handle and lsof utilities, it reads live /proc descriptor tables, /proc/locks, and /proc/net socket tables to reveal which files, pipes, event loops, locks, and sockets are held by running processes.
Key Features:
- Live Process File Descriptor Table: Enumerates accessible /proc/<pid>/fd links and /proc/<pid>/fdinfo flags (O_RDONLY, O_WRONLY, O_RDWR, O_APPEND, O_CLOEXEC, file offset, and mount ID) across running user and readable system processes.
- Socket Inode Cross-Reference: Maps socket:[inode] handles directly against live /proc/net/tcp, /proc/net/tcp6, /proc/net/udp, /proc/net/udp6, and /proc/net/unix tables to show local/remote IP:port endpoints, TCP states, and UNIX domain paths.
- Kernel File Locks & Unlinked Files: Inspects active POSIX, FLOCK, and OFD locks in /proc/locks and highlights open (deleted) unlinked files still occupying disk space.
- Descriptor Breakdown & Ulimit Telemetry: Renders an open descriptor category chart, tracks per-process FD soft/hard limits (/proc/<pid>/limits), and exports CSV and JSON reports.
