NEWGRP(1) FreeBSD General Commands Manual NEWGRP(1) NAME newgrp -- change to a new group SYNOPSIS newgrp [-l] [group] DESCRIPTION The newgrp utility creates a new shell execution environment with modi- fied real and effective group IDs. The options are as follows: -l Simulate a full login. The environment and umask are set to what would be expected if the user actually logged in again. If the group operand is present, a new shell is started with the speci- fied effective and real group IDs. The user will be prompted for a pass- word if they are not a member of the specified group. Otherwise, the real, effective and supplementary group IDs are restored to those from the current user's password database entry. DIAGNOSTICS The newgrp utility attempts to start the shell regardless of whether group IDs were successfully changed. If an error occurs and the shell cannot be started, newgrp exits >0. Otherwise, the exit status of newgrp is the exit status of the shell. SEE ALSO csh(1), groups(1), login(1), sh(1), su(1), umask(1), group(5), passwd(5), environ(7) STANDARDS The newgrp utility conforms to IEEE Std 1003.1-2001 (``POSIX.1''). HISTORY A newgrp utility appeared in Version 6 AT&T UNIX. BUGS Group passwords are inherently insecure as there is no way to stop users obtaining the crypted passwords from the group database. Their use is discouraged. FreeBSD 11.1 May 23, 2002 FreeBSD 11.1
