 +====== Grep Lines Before and After ======
  
 +I often need to grep a file and return a few lines before and a few lines after the line I'm looking for. There are three relevant command line Arguments that allow you to do that.
 +
 +Grep's //-B 1// option will give you one line before; //-A 1// will give you one line after; and -C 1 will give you both one line before and one line after.
 +
 +Here's an example.
 +
 +  grep -B 2 -A 3 '​captcha'​ ./​myfile.txt
