    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.
