title: How to remove a specific string common in multiple lines in a CSV file using shell script?
body: <p>I have a csv file which contains 65000 lines (Size approximately 28 MB). In each of the lines a certain path in the beginning is given e.g. "c:\abc\bcd\def\123\456". Now let's say the path "c:\abc\bcd\" is common in all the lines and rest of the content is different. I have to remove the common part (In this case "c:\abc\bcd\") from all the lines using a shell script. For example the content of the CSV file is as mentioned.</p>
  
  <pre><code>C:/Abc/Def/Test/temp\.\test\GLNext\FILE0.frag                   0   0   0
  C:/Abc/Def/Test/temp\.\test\GLNext\FILE0.vert                   0   0   0
  C:/Abc/Def/Test/temp\.\test\GLNext\FILE0.link-link-0.frag       16  24  3
  C:/Abc/Def/Test/temp\.\test\GLNext\FILE0.link-link-0.vert       87  116 69
  C:/Abc/Def/Test/temp\.\test\GLNext\FILE0.link-link-0.vert.bin   75  95  61
  C:/Abc/Def/Test/temp\.\test\GLNext\FILE0.link-link-0            0   0
  C:/Abc/Def/Test/temp\.\test\GLNext\FILE0.link-link-6            0   0   0 
  </code></pre>
  
  <p>In the above example I need the output as below</p>
  
  <pre><code>FILE0.frag                  0   0   0
  FILE0.vert                  0   0   0
  FILE0.link-link-0.frag      17  25  2
  FILE0.link-link-0.vert      85  111 68
  FILE0.link-link-0.vert.bin  77  97  60
  FILE0.link-link-0               0   0
  FILE0.link                  0   0   0
  </code></pre>
  
  <p>Can any of you please help me out with this?</p>
