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.
