attr | API for security modules (originally added for SELinux), present only if Kernel was compiled with CONFIG_SECURITY. |
autogroup | See man 7 sched |

cgroups | lists a process' cgroup membership. |
clear_refs | Clears page referenced bits shown in smaps output |
cmdline | A read-only file that stores a process's complete command line unless the process is a zombie. |
comm | |
coredump_filter | See man 5 core |
cpuset | Displays the path of the process's cpuset directory relative to the root of the cpuset filesystem. |
cwd | Symbolic link to the process's current working directory |
environ | The process's initial environment (environment variables). Entries are separated by null bytes and can be displayed with cat /proc/$pid/environ | tr '\000' '\n') |
exe | A symbolic link to the actual filename of the executed command. See also the field exe in struct mm_struct. |
fd | Contains a subdirectory(?) for each open file |
fdinfo | |
gid_map | See man 7 user_namespaces |
io | I/O statistics |
limits | Soft and hard limits, and their units of measurements |
map_files | |
maps | Currently mapped memory regions and their access permissions. |
mem | Access a process's memory. |
mountinfo | |
mounts | |
mountstats | |
net | See also /proc/net |

pagemap | Mapping of virtual pages to physical page frams or swap area. |
personality | |
root | The per-process filesystem root (chroot) |

smaps | Memory consumption for the process's mappings (The pmap command shows similar information) |
stack | Symbolic trace of function calls in kerne. stack (requires CONFIG_STACKTRACE) |
projid_map | |
smaps_rollup | Accumulated smaps stats for all mappings of the proces. This can be derived from smaps, but is faster and more convenient |
stat | Process status. See also fs/proc/array.c |
statm | Memory usage |
status | Displays the information of stat and statm in a more human friendly way. |
syscall | The number of the system call currently being executed and its values |
task | |
timers | List of POSIX timers |
timerslack_ns | |
uid_map | |
wchan | The symoblic name corresponding to the location in the kernel where the process is sleeping (requires CONFIG_KALLSYMS, see kallsyms). |
