NAME

peekfd - peek at file descriptors of running processes

SYNOPSIS

peekfd [-8] [-n] [-c] [-d] [-v] [-h] 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.

No long options are implemented.
