The newgrp command
Posted on Mon 20 July 2020 in dev-journal
newgrp is a convienient command I ran across today. You can run this command
after you add your user to a group. This allows you to continue without having
to logout and log back in for the group changes to take effect.
Here is the man page:

NAME
newgrp - log in to a new group
SYNOPSIS
newgrp [group]

newgrp changes the group identification of its caller, analogously to login(1). The same person remains logged in, and the current directory is unchanged, but calculations of access permissions to files are performed with respect to the new group ID.
If no group is specified, the GID is changed to the login GID.
FILES
/etc/group
/etc/passwd
SEE ALSO
login(1), group(5)
