Linux uses the dd command to quickly generate large files, and the linuxdd command to generate The dd command can easily create a specified size file, as shown in figure Dd if =/dev/zero of = test bs = 1 M count = 1000 A m test file is generated. The file content is 0 (because it is read from/dev/zero,/dev/zero is 0) However, the speed of writing files to the

To write time in standard format to log files. To convert time (now () to character format "YYYY-MM-DD hh: mm: SS Zzz" Write this function, Delphi system itself also with the Conversion Function formatdatetime ('yyyy-MM-DD hh: mm: SS zzz', now ()) You can also implement this function. Considering that this is a fixed-format conversion function for further optimization. // Actual test results Run 1,000,000 f

First, you must understand two special devices: /Dev/null: Recycle Bin, bottomless pit /Dev/Zero: generate characters Test the disk write capability TIME dd If =/dev/Zero of =/test. dbf bs = 8 k count = 300000 Because/dev // zero is a pseudo device, it only produces a null compaction stream and does not generate Io for it.

Write speed:TIME dd If =/dev/Zero of = test. dbf bs = 8 k count = 300000Among them,/dev/zero is a pseudo device, which only generates a null compaction stream and does not generate Io for it. Therefore, Io will be concentrated in the of file, and the of file is only used for writing, therefore, this command is equivalent to testing the disk write capability.The output result is similar (because the test time is generally longer and more accurate, you

1 The basic format of the DD commandDD if=xxx of=xxx bs=xxx count=xxx2 about BSBS reads and writes data in blocks, and every time a piece of data is read and written, BS is the size of the specified block. The size of this block can be arbitrary. This arbitrariness allows DD to do a lot of things, just to set the size of BS as needed.2.1 Getting the entire MBRDD IF=/DEV/SDA of=mbr.img bs=512 count=12.2 Get

Copy the CPP file from windows to Linux, or from Linux to another Linux. CPP ,. H files often fail to be compiled. It is revealed that three more "things" are added at the beginning, such as tray357. We can't see VI, because it's not a character, and we don't know what the situation is. We inserted three bits of data. At this time, we can only copy the file again, through the graphic interface, or command DD.

Format the USB flash disk first: Use fdisk-L to view the USB flash disk to the mount point, for example,/dev/sdb1. Unmount the USB flash disk and run the format command mkfs. vfat/dev/sdb1. Then re-mount the USB flash drive to create the boot disk: # dd if=/ntfs/linux_all/sys/CentOS-7.0-1406-x86_64-DVD.iso of=/dev/sdb Note that/dev/SDB is not/dev/sdb1 and an error is returned.In this case, you can re-open a terminal and run the
