The find util has co-dependency issues and likes its globbed args to be held...preferably between double-quotes.
Seriously, it does not always behave as expected on globbed -name args. You'll want to make sure and wrap your args in proper quotes to ensure that find can parse them properly.

I was trying to install db2 on Ubuntu, but got messed up with manual installation and Synaptic. At the moment, I find myself with a filesystem where DB2 is NOT installed ( I removed it with a sudo rm :o ) and with Synaptic still flagging db2exc as installed. The problem is that... (1 Reply)
I have this in my .profile:
stty erase `tput kbs`
which sets erase to ^H for a vt and ^? for an xterm.
This has been fine up until now on all systems whether I login using a vt terminal emulator or an xterm.
On this new system though, if I log in directly using an xterm, backspace doesn't... (1 Reply)

anyevent::callback
AnyEvent::Callback(3pm) User Contributed Perl Documentation AnyEvent::Callback(3pm)NAME
AnyEvent::Callback - callback aggregator for AnyEvent watchers.
SYNOPSIS
use AnyEvent::Callback;
# usually watchers are looked as:
AE::something @args, sub { ... };
AE::something
@args,
sub { ... }, # result
sub { ... }; # error
use AnyEvent::Callback;
AE::something @args, CB { ... };
AE::something @args,
CB sub { ... }, # result
sub { ... }; # error
AE::something @args,
CB sub { ... }, # result
sub { ... }, # error
sub { ... }; # anyway callback
Callback hierarchy
my $cbchild = $cb->CB(sub { ... });
...
$cbchild->error('error'); # will call $cb->error('error');
Inside Your callback You can:
sub my_watcher {
my $cb = pop;
my @args = @_;
# ...
$cb->error( @error ); # error callback will be called
# or:
$cb->( $value ); # result callback will be called
}
Callbacks stack
my $cbs = CBS;
for (1 .. $n) {
AE::something @args, $cbs->cb;
}
$cbs->wait(sub {
for (@_) {
if ($_->is_error) { # handle one error
my @err = $_->errors; # or:
my $errstr = $_->errstr;
} else { # results
my @res = $_->results;
}
}
});
DESCRIPTION
The module allows You to create callback's hierarchy. Also the module groups error and result callbacks into one object.
Also the module checks if one callback was called by watcher or not. If a watcher doesn't call result or error callback, error callback
will be called automatically.
Also the module checks if a callback was called reentrant. In the case the module will complain (using "carp" in Carp).
If a watcher touches error callback and if superior didn't define error callback, the module will call error callback upwards hierarchy.
Example:
AE::something @args, CB &my_watcher, &on_error;
sub on_error {
}
sub my_watcher {
my $cb = pop;
...
the_other_watcher $cb->CB( sub { # error callback wasn't defined
my $cb = pop;
...
yet_another_watcher1 $cb->CB( sub {
my $cb = pop;
...
$cb->( 123 ); # upwards callback
});
yet_another_watcher2 $cb->CB( sub {
my $cb = pop;
...
$cb->error( 456 ); # on_error will be called
});
});
}
METHODS
'CODE' (overloaded fake method)
$cb->( ... );
You can use the object as usually CODEREF.
CB
Creates new callback object that have binding on parent callback.
my $new_cb = $cb->CB(sub { ... }); # the cb doesn't catch errors
my $new_cb = CB(sub { ... }, sub { ... }); # the cb catches errors
my $new_cb = $cb->CB(sub { ... }, sub { ... }); # the same
error
Calls error callback. If the object has no registered error callbacks, parent object's error callback will be called.
$cb->error('WTF?');
