Описание (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.
Параметры (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.
