You need to look at the discussions of die() and warn() and the %SIG hash. You can set up your own handlers for errors (via die) using $SIG{__DIE__} = sub { ... } and for warnings (via warn) using $SIG{__WARN__} = sub { ... }. See the perlvar and perlfunc manpages. You can also run code that you think might die inside an eval { } construction and keep your program from dying.
#!/usr/bin/perl -w use strict; $SIG{__DIE__} = sub { die("My error: ", @_); }; $SIG{__WARN__} = sub { warn("My warning: ", @_); }; warn("some warning"); die("aarggh!");
