Se "man perlfaq". Den man side indeholder en masse spørgsmål om den slags
ting. Svaret på dette spørgsmål findes i undersiden "man perlfaq5".

       How do I change one line in a file/delete a line in a
       file/insert a line in the middle of a file/append to the
       beginning of a file?

       The general solution is to create a temporary copy of the
       text file with the changes you want, then copy that over
       the original.  This assumes no locking.
