I wrote a bash program to setup new Debian install’s…. but I can’t figure this problem/error out…… I can’t get it to copy a .bashrc file to a new users /home directory even with 777 permissions.
Here are the declarations and setting of the variables:
21 CURRENTDIR=/tmp/svaka 22 BASHRC=.bashrc 23 NANORC=.nanorc 24 BASHRCROOT=.bashrcroot
Here are the files the program uses and they are in the same directory the program runs from:
$ls -sail /tmp/svaka total 110 21 1 drwxrwxrwx 3 root root 1024 Sep 13 05:21 . 2 3 drwxrwxrwt 13 root root 3072 Sep 13 05:20 .. 34 4 -rwxrwxrwx 1 root root 3250 Sep 11 23:27 .bashrc 36 3 -rwxrwxrwx 1 root root 2517 Sep 11 23:27 .bashrcroot 31 1 -rwxrwxrwx 1 root root 524 Sep 11 23:27 changePasswords.bash 28 2 -rwxrwxrwx 1 root root 1235 Sep 11 23:27 checkSystem 42 1 -rwxrwxrwx 1 root root 594 Sep 13 04:29 checuserpass.sh 39 0 -rwxrwxrwx 1 root root 0 Sep 11 23:28 cpSuccessCodes.txt 25 8 -rwxrwxrwx 1 root root 8048 Sep 11 23:27 debianConfig_1.bash 32 11 -rwxrwxrwx 1 root root 10326 Sep 13 05:21 debianConfig_awsome.3.2.sh 33 4 -rwxrwxrwx 1 root root 3971 Sep 11 23:27 debianConfig.sh 35 9 -rwxrwxrwx 1 root root 8481 Sep 11 23:27 debianConfig_version.3.0.sh 38 7 -rwxrwxrwx 1 root root 6970 Sep 13 05:07 debianConfigVersion3.1ERRORS.txt 340 1 -rw-r--r-- 1 root root 1024 Sep 13 05:13 .debianConfigVersion3.1ERRORS.txt.swp 40 11 -rwxrwxrwx 1 root root 10658 Aug 3 2016 deb-multimedia-keyring_2016.8.1_all.deb 41 11 -rwxrwxrwx 1 root root 10658 Aug 3 2016 deb-multimedia-keyring_2016.8.1_all.deb.1 397 11 -rw-r--r-- 1 root root 10658 Aug 3 2016 deb-multimedia-keyring_2016.8.1_all.deb.2 43 3 drwxrwxrwx 6 root root 3072 Sep 13 05:01 nanorc 26 9 -rwxrwxrwx 1 root root 8833 Sep 11 23:27 .nanorc 30 1 -rwxrwxrwx 1 root root 862 Sep 11 23:27 sources.list 37 2 -rwxrwxrwx 1 root root 1723 Sep 11 23:27 ssh_config 27 3 -rwxrwxrwx 1 root root 2573 Sep 11 23:27 sshd_config 24 1 -rwxrwxrwx 1 root root 134 Sep 11 23:27 testing3892739.sh 22 1 -rwxrwxrwx 1 root root 772 Sep 11 23:27 testing.sh 29 1 -rwxrwxrwx 1 root root 71 Sep 11 23:27 userlist.txt 23 1 -rwxrwxrwx 1 root root 71 Sep 11 23:27 users.txt
Here is the code:
300 for user in "$@" 301 do 302 if [ "$user" = root ] 303 then 304 continue 305 fi 306 sudo -i -u "$user" user="$user" CURRENTDIR="$CURRENTDIR" BASHRC="$BASHRC" bash <<'EOF' 307 echo "usersBashrc" 308 if /bin/cp -f "$CURRENTDIR/$BASHRC" "$HOME/.bashrc" 309 then 310 echo "Copy for $user (bashrc) succeeded!" 311 sleep 3 312 else 313 echo "Couldn't cp .bashrc for user $user" 314 exit 127 315 fi 316 chown $user:$user "$HOME/.bashrc" || exit 127 317 chmod 644 "$HOME/.bashrc" 318 wget https://raw.github.com/trapd00r/LS_COLORS/master/LS_COLORS -O "$HOME"/.dircolors 319 echo 'eval $(dircolors -b $HOME/.dircolors)' >> "$HOME"/.bashrc 320 EOF 321 done
I can get it to work if I add this line:
chown $user:$user "$CURRENTDIR"/.bashrc
just before I enter the sudo
QUESTION:
My question is, shouldn’t I be able to copy the file because it has 777 permissions set read,write and execute even though I’m not the owner?

Answer
I can get it working if I change the quoting on the variable…..
/bin/cp "$CURRENTDIR/$BASHRC" "$HOME/.bashrc"
to
/bin/cp "$CURRENTDIR"/"$BASHRC" "$HOME/.bashrc"
I’m new to programming so I don’t have any explanations for this.
