title: Filter a txt(GTF) file based on another file
body: <p>Can someone please help me with an AWK problem? 
  I have a big GTF file like below. The 9th field contains gene_id I want to use.</p>
  
  <p><strong>file1.gtf</strong></p>
  
  <pre><code>chr1  hg38_refGene  exon         67127166   67127257   0.000000  -  .  gene_id  "NR_075077";  transcript_id  "NR_075077";
  chr1  hg38_refGene  exon         67131142   67131227   0.000000  -  .  gene_id  "NR_075077";  transcript_id  "NR_075077";
  chr1  hg38_refGene  exon         67134930   67134971   0.000000  -  .  gene_id  "NR_075077";  transcript_id  "NR_075077";
  chr1  hg38_refGene  start_codon  201283703  201283705  0.000000  +  .  gene_id  "NM_000299";  transcript_id  "NM_000299";
  chr1  hg38_refGene  CDS          201283703  201283904  0.000000  +  0  gene_id  "NM_000299";  transcript_id  "NM_000299";
  chr1  hg38_refGene  exon         201283452  201283904  0.000000  +  .  gene_id  "NM_000299";  transcript_id  "NM_000299";
  </code></pre>
  
  <p>I then have another file which has all the gene_id I would like to filter out from the rest.</p>
  
  <p><strong>file2.txt</strong></p>
  
  <pre><code>NM_000017
  NM_000019
  NM_000024
  NM_000033
  NM_000034
  </code></pre>
  
  <p>I would like the out put to be a filtered file1 with rows with gene_id I want to keep. Other solutions in python would also be appreciated.
  Thank you in advance!</p>
