Linux Learning-ls command
LS is the abbreviation of list, through the LS command not only can view the files contained in Linux folder, but also can view file permissions (including directories, folders, file permissions), view directory information, etc.
Common parameters and their functions:
LS-A lists all files in the directory, including hidden files that start with.
Ls-a list except. of other files
LS-R Reverse sequence arrangement
Ls-t to sort by file modification time
Ls-s sorted by file

Language Resources (LRS): LR can be understood as the text to be processed by IE. In gate, document objects are used to represent the texts that can be processed. Currently, XML, HTML, PDF, and other formats are supported, corpus is a collection of documents and can be processed as a whole.

The following describes the parameters of the sdo_geometry type:
1. sdo_gtype: indicates the geometric type to be stored, such as the DOT/line surface. It is expressed by the number type;
2. sdo_srid: geometric space reference coordinate system. The type is also number;
3. sdo_point: if it is of the geometric type, the point coordinate is stored; otherwise, it is null. The sdo_point_type customized by Oracle;

Less Optimization-> more optimization:
O0 --> O1 --> O2 --> O3
-O0 indicates no optimization,-O1 indicates the default value, and-O3 indicates the highest optimization level.
English explanation:
'-O'
'-O1'
Optimize. Optimizing compilation takes somewhat more time, and
Lot more memory for a large function.
With '-O', the compiler tries to reduce code size and execution
Time, without specify Ming any optimizations that take a great deal
Of compilation time.
'-O' turns on the following optimizatio
