how to check disk space on mac

Article Title: Restrict Linux users from occupying disk space during transition. Linux is a technology channel of the IT lab in China. Some basic categories, such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems, are now growing in size. May someone ask, do I still need to configure the disk quota? The a

Note: It is recommended to add a virtual disk file to increase disk space by adding LVM logical volumes to the virtual machine. The creation process is as follows. 1. DD Creates a disk file # dd If=/dev/zero bs=1024m count=4 >/data/test_01new.img 2. Turn off the test01 virtual machine 3. Modify the new virtual

The UNDO tablespace is used to store UNDO data. When you perform DML operations (INSERT, UPDATE, and DELETE), oracle writes the old data of these operations to the UNDO segment before oracle9i, The UNDO tablespace is used to store UNDO data. When you perform DML operations (INSERT, UPDATE, and DELETE), oracle writes the old data of these operations to the UNDO segment before oracle9i, There are two main causes:1. There is a large volume of transactions that allow Oracle Undo to automaticall

Oracle's restored tablespace UNDO is full of disk space. The specific steps to solve this problem are oracleundo.Zookeeper There are two main causes:1. There is a large volume of transactions that allow Oracle Undo to automatically expand, resulting in excessive disk space occupation;2. There are large transactions tha

We all know that the C disk is put on the installation system disk, if the C disk space is small, directly affect the speed of the system operation. So we generally do not put other software in C disk, has ensured the speed of the system to run. But recently some users of Wi

, when necessary, this part of inactive memory resources will be released as free for the program. The released part will be allocated to the virtual memory of the disk. (This is why the system speed is affected when the available disk space is less than 10 Gb ). Therefore, it is normal to have a small amount of free memory and a large amount of inactive memory i

Whether it's Windows or Mac, they produce a lot of cache and "junk" files, and recall that they don't seem to be downloading video or storing files recently, but disk space is really getting smaller. At this point, we need to manually or use Disk Cleanup software to intelligently clean up your Mac.If you have never cle

Today many users of the tablet or the Super user have installed WIN8 system in the system, but it is well known that the super and flat hard disk capacity is not high, many users in the installation of WIN8 system Live, and then install common software, even install games, and then through the system to generate cache files and automatic backup system, The rest of the disk

After compiling the source code last night, make reported the following error after a while: # A fatal error has been detected by the Java Runtime Environment:## SIGSEGV (0xb) at pc=0x40362d33, pid=12195, tid=2835454784## JRE version: 6.0_45-b06# Java VM: Java HotSpot(TM) Server VM (20.45-b01 mixed mode linux-x86 )# Problematic frame:# V [libjvm.so+0x158d33][error occurred during error reporting (printing problematic frame), id 0xb] After research, the hard

disk of the virtual machine is found to be 16 GB, but after entering the Linux system, use "DF-h" to check whether the hard disk space is as large as originally. Although the disk has been expanded, the Linux operating system cannot be identified because the file system has

Xcode disk space cleanupMy device is the MacBook Air ' Mid 2011,128g SSD. Some storage pressure has recently started, and after cleaning up part of the old files with clean My mac, I decided to do it for Xcode.Remove support for legacy devicesImpact: Can be regenerated and re-generated automatically when the old device is debugged. I removed 4.3.2, 5.0, 5.1 and o

OracleTo solve the problem, follow these steps: At the beginning, I planned to shrink the data file in the temporary tablespace. Run: SQL> alter database tempfile 2'/oracle/oms/oradata/temp/temp01.dbf' resize 10240 M; The database reports an error. The size of the reset space cannot meet the requirements. It seems that a new temporary tablespace needs to be created to replace the current tablespace. 1. First,

Most file systems retain a portion of the space for emergency purposes (such as when the hard disk space is full). This ensures that some key applications (such as databases) have room when the hard disk is full, instead, crash will immediately give the monitoring system and administrator some time to notice. However,

phone virus and garbage, free storage space. Workaround and steps: 1. Open My Computer--Folder Options--View--Show All files and folders, remove the "Hide protected system Files" tick, OK. Turn off System Restore: Right-click My Computer--Properties--System Restore--turn off System Restore on all disks, and delete the appropriate folder: C:system Volume information.2 2, shut down the system hibernation: Right-click on the desktop--Properties-
