If the effective and real IDs do not match, both + shall be written. If multiple groups are supported by + the underlying system (see the description of + {NGROUPS_MAX} in the System Interfaces volume of + IEEE Std 1003.1-2001), the supplementary group affilia- + tions of the invoking process shall also be written. + + If a user operand is provided and the process has the + appropriate privileges, the user and group IDs of the + selected user shall be written. In this case, effective + IDs shall be assumed to be identical to real IDs. If the + selected user has more than one allowable group member- + ship listed in the group database, these shall be writ- + ten in the same manner as the supplementary groups + described in the preceding paragraph. + +OPTIONS + The id utility shall conform to the Base Definitions + volume of IEEE Std 1003.1-2001, Section 12.2, Utility + Syntax Guidelines. + + The following options shall be supported: + + -G Output all different group IDs (effective, real, + and supplementary) only, using the format "%u\n" + . If there is more than one distinct group affil- + iation, output each such affiliation, using the + format " %u" , before the is output. + + -g Output only the effective group ID, using the + format "%u\n" . + + -n Output the name in the format "%s" instead of the + numeric ID using the format "%u" . + + -r Output the real ID instead of the effective ID. + + -u Output only the effective user ID, using the for- + mat "%u\n" . + + +OPERANDS + The following operand shall be supported: + + user The login name for which information is to be + written. + + +STDIN + Not used. + +INPUT FILES + None. + +ENVIRONMENT VARIABLES + The following environment variables shall affect the + execution of id: + + LANG Provide a default value for the internationaliza- + tion variables that are unset or null.

(On + systems with user and group IDs that are 32-bit integers + and with group names with a maximum of 8 bytes per name, + 93 supplementary groups plus distinct effective and real + group and user IDs could theoretically overflow the + 2048-byte {LINE_MAX} text file line limit on the default + output case. It would take about 186 supplementary + groups to overflow the 2048-byte barrier using id -G). + This is not expected to be a problem in practice, but in + cases where it is a concern, applications should con- + sider using fold -s before postprocessing the output of + id. + +EXAMPLES + None. + +RATIONALE + The functionality provided by the 4 BSD groups utility + can be simulated using: + + + id -Gn [ user ] + + The 4 BSD command groups was considered, but it was not + included because it did not provide the functionality of + the id utility of the SVID. Also, it was thought that it + would be easier to modify id to provide the additional + functionality necessary to systems with multiple groups + than to invent another command. + + The options -u, -g, -n, and -r were added to ease the + use of id with shell commands substitution. Without + these options it is necessary to use some preprocessor + such as sed to select the desired piece of information. + Since output such as that produced by: + + + id -u -n + + is frequently wanted, it seemed desirable to add the + options. + +FUTURE DIRECTIONS + None. + +SEE ALSO + fold , logname , who , the System Interfaces volume of + IEEE Std 1003.1-2001, getgid(), getgroups(), getuid() + +COPYRIGHT + Portions of this text are reprinted and reproduced in + electronic form from IEEE Std 1003.1, 2003 Edition, + Standard for Information Technology -- Portable Operat- + ing System Interface (POSIX), The Open Group Base Speci- + fications Issue 6, Copyright (C) 2001-2003 by the Insti- + tute of Electrical and Electronics Engineers, Inc and + The Open Group.
