PEEKFD(1) User Commands PEEKFD(1)
peekfd - peek at file descriptors of running processes
peekfd [-8,--eight-bit-clean] [-n,--no-headers] [-f,--follow]
[-d,--duplicates-removed] [-V,--version] [-h,--help] pid [fd] [fd] ...
peekfd attaches to a running process and intercepts all reads and
writes to file descriptors. You can specify the desired file descrip-
tor numbers or dump all of them.
-8 Do no post-processing on the bytes being read or written.
-n Do not display headers indicating the source of the bytes
-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.
Not used but useful for the user to look at to get good file
The following diagnostics may be issued on stderr:
Error attaching to pid ...
An unknown error occurred while attempted to attach to a
process.. you may need to be root.
Probably lots. Don't be surprised if the process you are monitoring
