Question

我写了一个bash程序来设置新的Debian安装程序...。但是我无法弄清楚这个问题/错误...我无法获取将.bashrc文件复制到新用户的信息。 /home目录，即使具有777权限。

以下是变量的声明和设置：

 21 CURRENTDIR=/tmp/svaka
 22 BASHRC=.bashrc
 23 NANORC=.nanorc
 24 BASHRCROOT=.bashrcroot

以下是程序使用的文件，它们位于程序运行所在的目录中：

$ls -sail /tmp/svaka

 23  1 -rwxrwxrwx  1 root        root           71 Sep 11 23:27 users.txt

代码如下：

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

如果添加以下行，我可以使它工作：

chown $user:$user "$CURRENTDIR"/.bashrc

在我输入sudo

之前

问题：

我的问题是，我是否应该copy file，因为它具有777个权限集read，write和{{1} }，即使我不是所有者？

编辑＃1：

execute

Answer 1

如果更改变量的引用，我可以使它工作.....

/bin/cp "$CURRENTDIR/$BASHRC" "$HOME/.bashrc"

到

/bin/cp "$CURRENTDIR"/"$BASHRC" "$HOME/.bashrc"

我是编程新手，所以对此没有任何解释。

即使我在文件上使用`/ bin / cp`和chmod 777，在bash脚本中复制也会失败
