provides a command-line interface to several SQL SHOW
statements. See Section 13.7.5, “SHOW
Syntax”. The same information can be obtained by using
those statements directly. For example, you can issue them
from the mysql client program.

columns for which you have some privileges.
If the last
argument contains shell or SQL wildcard characters
(“*”, “?”, “%”, or
“_”), only those names that are matched by the
wildcard are shown. If a database name contains any
underscores, those should be escaped with a backslash (some
Unix shells require two) to get a list of the proper tables
or columns. “*” and “?” characters
are converted into SQL “%” and “_”
wildcard characters. This might cause some confusion when
you try to display the columns for a table with a
“_” in the name, because in this case,
mysqlshow shows you only the table names that match
the pattern. This is easily fixed by adding an extra
“%” last on the command line as a separate
