The command "tar xvf ${select}" is used to extract the contents of a tar archive file.
Here's what each part of the command means:
-
"tar" is the command itself, which stands for "tape archive." It is a program used to create, maintain, and extract archive files.
-
"x" is the option that tells the tar command to extract the contents of the archive file.
-
"v" is another option that stands for "verbose." It displays detailed information about the extraction process while it is happening.
-
"f" is used to specify the path or name of the tar archive file that you want to extract.
-
"${select}" is a placeholder for the actual name or path of the tar archive file. The "$" sign before "select" is used to reference the value of the variable named "select" in a shell script or command line.
So when you run this command, it will extract the contents of the specified tar archive file and display detailed information about the extraction process.
