15 | This manual page documents the GNU version of i\bid\bd. i\bid\bd | |
16 | prints information about the given user, or the process | |
17 | running it if no user is specified. By default, it prints | |
18 | the real user ID, real group ID, effective user ID if dif- | |
19 | ferent from the real user ID, effective group ID if dif- | |
20 | ferent from the real group ID, and supplemental group IDs. | |
21 | It prints each of these values preceded by a string iden- | |
22 | tifying it and followed by the corresponding user or group | |
23 | name in parentheses. | |
24 | ||
25 | The options cause i\bid\bd to print only part of the above | |
26 | information. | |

29 | -_\bg, --_\bg_\br_\bo_\bu_\bp | |
30 | Print only the group ID. | |
31 | ||
32 | -_\bn, --_\bn_\ba_\bm_\be | |
33 | Print the user or group name instead of the ID num- | |
34 | ber. Requires -_\bu, -_\bg, or -_\bG. | |
35 | ||
36 | -_\br, --_\br_\be_\ba_\bl | |
37 | Print the real, instead of effective, user or group | |
38 | ID. Requires -_\bu, -_\bg, or -_\bG. | |
39 | ||
40 | -_\bu, --_\bu_\bs_\be_\br | |
41 | Print only the user ID. | |
42 | ||
43 | -_\bG, --_\bg_\br_\bo_\bu_\bp_\bs | |
44 | Print only the supplementary groups. | |
45 | ||
46 | The long-named options can be introduced with `+' as well | |
47 | as `--', for compatibility with previous releases. Even- | |
48 | tually support for `+' will be removed, because it is | |
49 | incompatible with the POSIX.2 standard. | |
