title: How to copy contents from one CSV into another CSV with powershell?
body: <p>i have 2 csv files:
  each got 3 columns ,
  i want to compare the first column and if it matches it will copy the content in the other columns
  for example:</p>
  <p>1 csv:</p>
  <pre><code>column1   column2    column3
  aaa       bla        baba
  ccc       bla        babab3
  abc       bla        bababa3
  </code></pre>
  <p>2 csv:</p>
  <pre><code>column1   column4     column5
  abc       dla2        blabla2
  ddd       dla         blabla
  ccc       dla1        blabla1
  aaa       dla1        blabla1
  </code></pre>
  <p>updated csv:</p>
  <pre><code>column1   column2   column3   column4   column5 
  aaa       bla        baba     dla1      blabla1
