ldconfig:tldr:f46e9
This command performs two subsequent operations:
-
ldconfig -p
: Theldconfig
command is used to configure dynamic linker run-time bindings. The-p
flag is used to print the current list of cached dynamic linker libraries. This command displays information about all the libraries (shared object files) that the linker is aware of and their corresponding paths. -
| grep ${library_name}
: The vertical bar (|
) is a pipe character that redirects the output of the previous command as input to thegrep
command.grep
is a command-line utility used to search for specific patterns or text within files or given input. In this case, it is used to filter the output ofldconfig -p
to only show the lines containing the${library_name}
.
So, overall, the command ldconfig -p | grep ${library_name}
lists all the dynamic linker libraries and their paths, but it only displays the lines that match the ${library_name}
provided as a variable.
