Hello,
the "bash shell startup files" section can be improved:
1) /etc/profile tests for EUID=0 in two different ways:
|if [ $EUID -eq 0 ] ; then
pathappend /sbin:/usr/sbin
unset HISTFILE
fi|
|if [[ $EUID == 0 ]] ; then
PS1="$RED\u [ $NORMAL\w$RED ]# $NORMAL"
else
PS1="$GREEN\u [ $NORMAL\w$GREEN ]\$ $NORMAL"
fi
|
Please remove the "==" construction, it is completely unneeded here,
"-eq" works just fine. Also, "#" can be replced with "\$", too.
2) /etc/profile.d/extrapaths.sh uses the [ -d /usr/local/sbin -a $EUID
-eq 0 ] construction, but the "-a" doesn't work in all shells (try
posh). Suggestion: [ -d /usr/local/sbin ] && [ $EUID -eq 0 ]
3) /etc/profile.d/readline.sh is completely unneeded - readline-5.2
looks in /etc/inputrc by default.
4) It should be mentioned that umask (as set in the book) doesn't work
for non-shell logins (e.g., scp or svn-over-ssh). A recommendation to
use pam-umask
(http://ftp.debian.org/debian/pool/main/p/pam-umask/pam-umask_0.04.tar.gz)
may be more suitable.||
