PEEKFD(1) User Commands PEEKFD(1)
NAME
peekfd - peek at file descriptors of running processes
SYNOPSIS
peekfd [-8,--eight-bit-clean] [-n,--no-headers] [-f,--follow] [-d,--duplicates-removed] [-V,--version] [-h,--help] pid [fd] [fd] ...
DESCRIPTION
peekfd attaches to a running process and intercepts all reads and writes to file descriptors. You can specify the desired file descriptor
numbers or dump all of them.
OPTIONS
-8 Do no post-processing on the bytes being read or written.
-n Do not display headers indicating the source of the bytes dumped.
-c Also dump the requested file descriptor activity in any new child processes that are created.
-d Remove duplicate read/writes from the output. If you're looking at a tty with echo, you might want this.
-v Display a version string.
-h Display a help message.
FILES
/proc/*/fd
Not used but useful for the user to look at to get good file descriptor numbers.
ENVIRONMENT
None.
DIAGNOSTICS
The following diagnostics may be issued on stderr:
Error attaching to pid ...
An unknown error occured while attempted to attach to a process.. you may need to be root.
BUGS
Probably lots. Don't be surprised if the process you are monitoring dies.
