I have two files

```
file1 
non-coding  X   FlyBase gene    20025099    20025170    .   +   .   gene_id "FBgn0052826"; gene_symbol "tRNA:Pro-CGG-1-1";
non-coding  X   FlyBase gene    19910168    19910521    .   -   .   gene_id "FBgn0052821"; gene_symbol "CR32821";
non-coding  X   FlyBase gene    476857  479309  .   -   .   gene_id "FBgn0029523"; gene_symbol "CR18275";
non-coding  X   FlyBase gene    15576355    15576964    .   +   .   gene_id "FBgn0262163"; gene_symbol "betaNACtes5";
non-coding  X   FlyBase gene    19910168    19910521    .   -   .   gene_id "FBgn0052821"; gene_symbol "CR32821";

file2
betaNACtes5
CR18275
28SrRNA-Psi:CR45859
CR32821

```

What I want: if there is a match of any line in file2 with column 13 (partial match because of the " ") of file1 I want to change the string in column 4 to "pseudogene" otherwise nothing should be done.

```
Desired output

non-coding  X   FlyBase gene    20025099    20025170    .   +   .   gene_id "FBgn0052826"; gene_symbol "tRNA:Pro-CGG-1-1";
non-coding  X   FlyBase pseudogene  19910168    19910521    .   -   .   gene_id "FBgn0052821"; gene_symbol "CR32821";
non-coding  X   FlyBase gene    476857  479309  .   -   .   gene_id "FBgn0029523"; gene_symbol "CR18275";
non-coding  X   FlyBase pseudogene  15576355    15576964    .   +   .   gene_id "FBgn0262163"; gene_symbol "betaNACtes5";
non-coding  X   FlyBase pseudogene  19910168    19910521    .   -   .   gene_id "FBgn0052821"; gene_symbol "CR32821";

```

So far I can get the matches, but I can't do the rest.

```
grep -Ff file2 file1

```
