I also find it easier to open a root shell, do the work, and log out.
I put this line in /root/.bashrc to show a bright red prompt while I
am logged in as root. When I've got 6 terminals open at once the
color helps me keep track of which one is root.
export PS1='\[\e[1;31m\]\h:\w\$ \[\e[0m\]'
This line sets the primary prompt for the bash shell. Here are the
meanings of the codes:
\[ Beginning of sequence of non-printing characters
\e[1;31m ANSI Escape sequence to select Bold Red foreground color
\] End of sequence of non-printing characters
\h Print host name
: Print :
\w Print working directory
\$ Print $ (# for root user)
Print space
\[ Beginning of sequence of non-printing characters
\e[0m ANSI Escape sequence to remove all text attributes
\] End of sequence of non-printing characters
