make:tldr:2ccbb
make: Call a specific target, executing 4 jobs at a time in parallel.
$ make -j${4} ${target}
try on your machine
This command is using the "make" utility, which is commonly used to compile and build software projects. The "-j" option is used to specify the number of parallel tasks that can be executed simultaneously by make. In this case, the value is "${4}", which suggests that the number of concurrent tasks will be determined by the value of the fourth argument passed to the command.
The "${target}" part of the command specifies the specific target that make should build. A target can be a file, a section of code, or even a specific action to perform. The value of "${target}" is expected to be provided as an argument when running the command.
