Hi all
This feels like a really dumb question but doing a regex find and
replace is it possible to delete a line? For example,
for (@file) {
s/foo//g;
}
which equates to:
for each element in array 'file' if you find 'foo' then replace it with
null.
I then write the array to a file (using Tie::File) and it leaves a blank
line where the element containing 'foo' was like:
null
foo1
foo2
foo3
Perhaps I am confabulating two ideas here? Is there a way to walk
through an array and find a particular array element and delete it
rather than replace it with null (and then write it out to a file using
Tie::File)?
Thanks
James Turnbull
