9 * Deviations from posix: no -n because /proc/self/wchan exists; we use -n to
11 * Posix says default output should have field named "TTY" but if you "-o tty"
13 * Similarly -f outputs USER but calls it UID (we call it USER).
14 * It also says that -o "args" and "comm" should behave differently but use
16 * Select by session id is -s not -g. Posix doesn't say truncated fields
19 * Posix defines -o ADDR as "The address of the process" but the process
21 * field always prints "-" with an alignment of 1, which is why it has 11
22 * characters left for "cmd" in in 80 column "ps -l" mode. On x86-64 you
23 * need 12 chars, leaving nothing for cmd: I.E. posix 2008 ps -l mode can't
24 * be sanely implemented on 64 bit Linux systems. In procps there's ps -y
25 * which changes -l by removing the "F" column and swapping RSS for ADDR,
26 * leaving 9 chars for cmd, so we're using that as our -l output.
28 * Added a bunch of new -o fields posix doesn't mention, and we don't
29 * label "ps -o command,args,comm" as "COMMAND COMMAND COMMAND". We don't
30 * output argv[0] unmodified for -o comm or -o args (but procps violates
31 * posix for -o comm anyway, it's stat[2] not argv[0]).
36 * even though you can -o AIO there, to give sysadmins the option
39 * TODO: ps aux (att & bsd style "ps -ax" vs "ps ax" behavior difference)
40 * TODO: switch -fl to -y
41 * TODO: thread support /proc/$d/task/%d/stat (and -o stat has "l")
45 * TODO: pgrep -f only searches the amount of cmdline that fits in toybuf.
46 * TODO: pgrep qemu-system-i386 never matches because one char too long
