Fedora には 2 人のユーザーがいます。
- ワニ
- ルート (非常に明白です!)
ユーザーWaniの.bashrcの内容は次のとおりです。
# .bashrc
echo "Hello"
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# User specific aliases and functions
root にログインした後、次のコマンドを入力します。
[root@Dell Wani]# touch try.txt
[root@Dell Wani]# service sshd start
[root@Dell Wani]# scp try.txt Wani@localhost:~/
Wani@localhost's password:
Hello
[root@Dell Wani]#
Wani にログインして、次のように入力します。
[Wani@Dell ~]$ cat try.txt
cat: try.txt: No such file or directory
[Wani@Dell ~]$
ここで、再度ルートにログインし、同じコマンドを次のように入力し-vます。
[root@Dell Wani]# scp -v morph.log Wani@localhost:

ここで正確に何が起こったのか、誰か光を当てることができますか? ファイルがルートから Wani にコピーされなかったのはなぜですか?
