I have an array like this:
@arrAlph = ('wer', 'abc', 'xyz', ... 'abc', ..);

I want to delete all the 'abc' s from it. They maybe at any position.
Is there an easy method?

You can use grep to filter out all the 'abc's and assign redult to a new array.

@arrAlph = ('wer', 'abc', 'xyz', 'fds', 'abc', 'dds');
@newAlph = grep(!/abc/,@arrAlph);
# copy back to original array if needed
@arrAlph = @newAlph;
print(@arrAlph);

#You can assign to the same array
@arrAlph = grep !/abc/,@arrAlph;
#but that will also elimitate elements like 'xyzabcdef'
#if you only want to eliminate 'abc'
@arrAlph = grep $_ ne 'abc',@arrAlph;
#or
@arrAlph = grep {$_ ne 'abc'} @arrAlph;
