The array@INC contains the list of places that thedo EXPR,require, oruse constructs look for their library files. It initially consists of the arguments to any-I command-line switches, followed by the default Perl library, probably/usr/local/lib/perl. Prior to Perl 5.26,. -which represents the current directory, was included in@INC; it has been removed. This change in behavior is documented inPERL_USE_UNSAFE_INC and it is not recommended that. be re-added to@INC. If you need to modify@INC at runtime, you should use theuse lib pragma to get the machine-dependent library properly loaded as well:
use lib '/mypath/libdir/';use SomeMod;You can also insert hooks into the file inclusion system by putting Perl code directly into@INC. Those hooks may be subroutine references, array references or blessed objects. See"require" in perlfunc for details.
