Next, please follow the small series to learn together!

The modprobe command is used to intelligently load and remove modules from the kernel.

modprobe automatic processing loadable module

modprobe can load a specified individual module or a group of dependent modules. modprobe determines which modules to load based on the dependencies created by depmod. If an error occurs during loading, modprobe unloads the entire set of modules.

syntax modprobe(option)(parameter) option-a or--all: loads all modules; -c or--show-conf: displays settings for all modules; -d or--debug: uses troubleshooting mode; -l or--list: displays available modules; -r or--remove: automatically unloads modules when unused; -t or--type: specifies module type; -v or--verbose: displays detailed information when executed; -V or--version: displays version information;-help： Show help. Parameter Module Name: The name of the module to load or remove.

Examples View modules profiles:

modprobe -c Here, you can check the configuration file of modules, such as what the alias name of the module is. A number of lines of information are printed, such as one line that looks like this:

alias symbol:ip_conntrack_unregister_notifier ip_conntrack lists all modules in the kernel that are mounted or not mounted:

modprobe -l Here, we can view the modules we need and mount them according to our needs; in fact, the module list read by modprobe -l is located in/lib/modules/\uname -r \directory; where uname -r is the version of the kernel, for example, one of the lines of the output result is:

/lib/modules/2.6.18-348.6.1.el5/kernel/net/netfilter/xt_statistic.ko Mount vfat modules:

modprobe vfat Here, mount a module using the format modprobe module name. After mounting, you can use lsmod to view mounted modules. Module names cannot have suffixes, and all modules we see with modprobe -l have.ko or.o suffixes.

Remove already loaded modules:

modprobe -r module name Here, remove the loaded module, same function as rmmod.

At this point, the study of "how to use Linux modprobe command" is over, hoping to solve everyone's doubts. Theory and practice can better match to help you learn, go and try it!
