,/sbin,/usr/ Bin,/usr/sbin wait in path, your current directory is usually not in path, so write mayuan.sh will not find the command, to use. /mayuan.sh told the system that it was looking in the current directory. As shown in the following:2. As an interpreter parameterThis works by running the interpreter directly, whose parameters are the file names of the shell scripts, such as:/bin/bash mayuan.shThe script that runs this way does not need to specify the interpreter information in the first

system continuously provides fast response times. 3 . ScalabilityXFS is a full 64-bit file system that can support up to million T bytes of storage space. Support for oversized files and small file sizes is outstanding and supports a large number of directories. XFS uses a high table structure to ensure that the file system can be quickly searched and quickly allocated to space. XFS continues to provide high-speed operations, and the performance of the file system is not limited by the number o

/O multiplexing techniques can be used to process multiple client access requests. / oMultiplexing allows multiple I/O blocking to be multiplexed to the same select block, allowing the system to handle more than one single threadClient requests. Compared with the traditional multi-threaded/multi-process model, the greatest advantage of I/O multiplexing is that the system overhead is small and the system does not need to createNew additional processes or threads, and do not need to maintain the o

Redis is one of the most popular NoSQL systems today, and it is a key-value storage system. Similar to memcached, but largely compensates for the lack of memcached, which supports storing more value types, including string, list, set, Zset, and hash. These data types support Push/pop, Add/remove, and intersection sets and differences, and richer operations. Based on this, Redis supports sorting in a variety of different ways. Redis data is cached in the computer's memory and periodically writes
