Test: -xtype c
This test behaves the same as ‘-type’ unless the file is a symbolic link. If the file is a symbolic link,
the result is as follows (in the table below, ‘X’ should be understood to represent any letter except ‘l’):
‘‘-P -xtype l’’
True if the symbolic link is broken
‘‘-P -xtype X’’
True if the (ultimate) target file is of type ‘X’.
‘‘-L -xtype l’’
Always true
‘‘-L -xtype X’’
False unless the symbolic link is broken
