NAME

6       peekfd - peek at file descriptors of running processes
7

SYNOPSIS

9       peekfd     [-8,--eight-bit-clean]    [-n,--no-headers]    [-f,--follow]
10       [-d,--duplicates-removed] [-V,--version] [-h,--help] pid [fd] [fd] ...
11

DESCRIPTION

13       peekfd attaches to a running  process  and  intercepts  all  reads  and
14       writes  to file descriptors.  You can specify the desired file descrip‐
15       tor numbers or dump all of them.
16

OPTIONS

18       -8     Do no post-processing on the bytes being read or written.
19
20       -n     Do not display  headers  indicating  the  source  of  the  bytes
21              dumped.
22
23       -c     Also  dump  the  requested  file  descriptor activity in any new
24              child processes that are created.
25
26       -d     Remove duplicate read/writes from the output.  If you're looking
27              at a tty with echo, you might want this.
28
29       -v     Display a version string.
30
31       -h     Display a help message.
32
