/dev/shm/is a very useful directory for Linux because it is not on the hard disk, but in memory. Therefore, under Linux, it is not necessary to build RAMDisk, the direct use of/dev/shm/can achieve a good optimization effect.One of the/dev/shm/needs to be aware of is the capacity issue, which, under Linux, defaults to half the size of memory and can be seen using

When we need special use, we can use other labels. For example, output a program's error message to the log file:./program 2>log. The standard output is still on the screen, but the error message is output to the log file.In addition, redir

An Introduction /dev/shm/is the next most useful directory for Linux because it's not on the hard drive, it's in memory. Therefore, under Linux, there is no need for a lot of trouble to build RAMDisk, direct use of/dev/shm/can achieve a very good optimization effect. One of the/dev/shm/to note is the capacity problem, which, under Linux, defaults to a maximum of

In Linux/unix, the information generally seen on the screen is from stdout (standard output) or stderr (standard error Output). Many people will ask, output is output, sent to the screen does not have, why is divided into stdout and stderr it? That is because in the server environment, almost all of the programs are run in background, so, in order to facilitate debug, generally in the design process, the STDOUT sent to/saved to a file, the wrong information stderr saved to different files.Which
