海外TECH	DEV Community	LINUX FILE SYSTEM	https://dev.to/yudistira19_21/linux-file-system-5afg	LINUX FILE SYSTEM Examining File SystemsTo get an overview of local and remote file system devices and the amount of free space available run the df command When the df command is run without arguments it reports total disk space used disk space free disk space and the percentage of the total disk space used on all mounted regular file systems It reports on both local and remote file systems The following example displays the file systems and mount points on host The partitioning on the host system shows two physical file systems which are mounted on and boot This is common for virtual machines The tmpfs and devtmpfs devices are file systems in system memory All files written into tmpfs or devtmpfs disappear after system reboot To improve readability of the output sizes there are two different human readable options h or H The difference between these two options is that h reports in KiB MiB or GiB while the H option reports in SI units KB MB or GB Hard drive manufacturers usually use SI units when advertising their products For more detailed information about space used by a certain directory tree use the du command The du command has h and H options to convert the output to human readable format The du command shows the size of all files in the current directory tree recursively Show a disk usage report for the usr share directory on host Identifying the Block DeviceA hot pluggable storage device whether a hard disk drive HDD or solid state device SSD in a server caddy or a USB storage device might be plugged into a different port each time they are attached to a system Use the lsblk command to list the details of a specified block device or all the available devices The lsblk fp command lists the full path of the device along with the UUIDs and mount points as well as the type of file system in the partition If the file system is not mounted the mount point will be blank Unmounting File SystemsThe shutdown and reboot procedures unmount all file systems automatically As part of this process any file system data cached in memory is flushed to the storage device thus ensuring that the file system suffers no data corruption umount mnt dataUnmounting is not possible if the mounted file system is in use For the umount command to succeed all processes needs to stop accessing data under the mount point In the example below the umount fails because the file system is in use the shell is using mnt data as its current working directory generating an error message root host cd mnt data root host data umount mnt dataumount mnt data target is busy The lsof command lists all open files and the process accessing them in the provided directory It is useful to identify which processes currently prevent the file system from successful unmounting root host data lsof mnt dataCOMMAND PID USER FD TYPE DEVICE SIZE OFF NODE NAMEbash root cwd DIR mnt datalsof root cwd DIR mnt datalsof root cwd DIR mnt dataLocating Files by NameThe locate command finds files based on the name or path to the file It is fast because it looks up this information from the mlocate database However this database is not updated in real time and it must be frequently updated for results to be accurate This also means that locate will not find files that have been created since the last update of the database The locate database is automatically updated every day However at any time the root user can issue the updatedb command to force an immediate update updatedbThe locate command restricts results for unprivileged users In order to see the resulting file name the user must have search permission on the directory in which the file resides Search for files with passwd in the name or path in directory trees readable by user on host locate passwdThe i option performs a case insensitive search With this option all possible combinations of upper and lowercase letters match the search locate i messagesThe n option limits the number of returned search results by the locate command The following example limits the search results returned by locate to the first five matches locate n snow png Searching for Files in Real TimeThe find command locates files by performing a real time search in the file system hierarchy It is slower than locate but more accurate It can also search for files based on criteria other than the file name such as the permissions of the file type of file its size or its modification time The find command looks at files in the file system using the user account that executed the search The user invoking the find command must have read and execute permission on a directory to examine its contents The first argument to the find command is the directory to search If the directory argument is omitted find starts the search in the current directory and looks for matches in any subdirectory To search for files by file name use the name FILENAME option With this option find returns the path to files matching FILENAME exactly For example to search for files named sshd config starting from the directory run the following command find name sshd config etc ssh sshd config THANKYOU	2022-09-25 13:08:06
