dmesg:查看核心启动日志
free:显示内存使用情况
uname -a :显示系统信息
tail 查看文件尾
例:tail -100f game.log 查看文件最后100行,持续刷新,适合在服务器上看实时日志时使用
查看指定端口是哪个服务在使用:

Linux杂记
此帖子用于记录使用Linux过程中遇到的各种小问题。
1、使用ln命令跨分区链接目录时,报错“目录链接出错”。
答:2.4 kernel以上,可以用mount –bind命令来链接。
The bind mounts. Since Linux 2.4.0 it is possible to remount part of the file hierarchy somewhere else. The call is mount --bind olddir newdir or shortoption mount -B olddir newdir or fstab entry is: /olddir /newdir none bind After this call the same contents is accessible in two places. One can also remount a single file (on a single file). It's also possible to use the bind mount to create a mountpoint from a regular directory, for example: mount --bind foo foo The bind mount call attaches only (part of) a single filesystem, not possible submounts. The entire file hierarchy including sub‐ mounts is attached a second place using mount --rbind olddir newdir or shortoption mount -R olddir newdir Note that the filesystem mount options will remain the same as those on the original mount point, and cannot be changed by passing the -o option along with --bind/--rbind. The mount options can be changed by a separate remount command, for exam‐ ple: mount --bind olddir newdir mount -o remount,ro newdir Note that behavior of the remount operation depends on the /etc/mtab file. The first command stores the 'bind' flag to the /etc/mtab file and the second command reads the flag from the file. If you have a system without the /etc/mtab file or if you explicitly define source and target for the remount command (then mount(8) does not read /etc/mtab), then you have to use bind flag (or option) for the remount command too. For example: mount --bind olddir newdir mount -o remount,ro,bind olddir newdir
在Linux下如何打开bitlocker加密的硬盘
我们这里用到一款叫做dislocker的工具,它可以在Linux或者Mac OSX中,读写被Windows Bitlocker加密的卷。它的GitHub地址:https://github.com/Aorimn/dislocker
以下是我的操作步骤:
1、创建两个文件夹,用来挂载被解锁的文件块和硬盘上的文件,我这里分别在/media目录下创建了windows文件夹和mount文件夹,打开终端(Ctrl+Alt+T),输入下面的命令:
$sudo mkdir /media/windows $sudo mkdir /media/mount/
