newgrp

newgrp(1)						      General Commands Manual							 newgrp(1)

NAME

       newgrp - switch to a new group

SYNOPSIS

       [group]

DESCRIPTION

       The command changes your group ID without changing your user ID and replaces your current shell with a new one.

       If  you	specify group, the change is successful if group exists and either your user ID is a member of the new group, or group has a pass-
       word and you can supply it from the terminal.

       If you omit group, changes to the group specified in your entry in the password file,

       Whether the group is changed successfully or not, or the new group is the same as the old one or not,  proceeds	to  replace  your  current
       shell  with  the  one  specified  in  the  shell field of your password file entry.  If that field is empty, uses the POSIX shell, (see sh-
       posix(1)).

       If you specify (hyphen) as the first argument, the new shell starts up as if you had just logged in.  If you omit the new shell	starts	up
       as if you had invoked it as a subshell.

       You  remain logged in and the current directory is unchanged, but calculations of access permissions to files are performed with respect to
       the new real and effective group IDs.

       Exported variables retain their values and are passed to the new shell.	All unexported variables are deleted, but the new shell may  reset
       them to default values.

       Since  the  current  process  is replaced when the new shell is started, exiting from the new shell has the same effect as exiting from the
       shell in which was executed.

EXTERNAL INFLUENCES

   International Code Set Support
       Characters from the 7-bit USASCII code set are supported in group names (see ascii(5)).

DIAGNOSTICS

       The command issues the following error messages:

       Your user		     ID does not qualify as a group member.

       The group name does not exist in

       If a password is required, it must come from a terminal.

       Standard input is not a terminal file,
				     causing the new shell to fail.

EXAMPLES

       To change from your current group to group without executing the login routines:

WARNINGS

       There is no convenient way to enter a password into

       The use of group passwords is not recommended because, by their very nature, they encourage poor security practices.  Group  passwords  may
       be eliminated in future HP-UX releases.

       If  the	specified group to has multiple inconsistent entries (i.e. the group id or/and password are different) in the group database, will
       consider the group id and password of the first matched group entry as the correct group id and password for the group.

FILES

       System group file
       System password file
