              本文解说了Linux建立文件下令的要领 ,希望对您的学习有所资助  。

              建立文件夹

              mkdir aaa

              mkdir -p aaa

              建立文件下令

              vi foo.txt

              emacs foo.txt

              echo "aaaa" > foo.txt

              cat > foo.txt

              扫除下令

              > foo.txt

              mkdir /home/u1 建立文件夹/home/u1

              chown oracle /home/u1 表现改变目录所有者为oracle账户;

              chgrp dba /home/u1 改变/home/u1目录为dba所有;

              chmod 755 /home/u1 表现oracle账户对/home/u1目录有755权限;

              rmdir /home/u1 表现删除/home/u1目录

              hostname可以检察linux的盘算机名;

              whoami可以检察当前用户;

              pwd显示当前路径;

              df检察系统的硬件信息

              ls -lrt l表现显示详细列表  ,-t表现定时间排序,-r反向排序

              cat orcl_ora_3436.trc|grep bucket

              以下检察相关文件内容:

              more /etc/oratab

              cat /etc/passwd

              cat /etc/group

              以上是Linux建立文件下令的要领
