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.
