  `grep(1)']  To  rapidly  scan  a  file  or  set  of  files  looking  for  a  particular 
  string  or  pattern  (when  browsing  through  a  large  set  of  files,  one

  information  science>    A  {Unix}  command  for 
  searching  files  for  lines  matching  a  given  {regular 
  expression}  (RE).  Named  after  the  {qed}/{ed}  editor 
  subcommand  "g/re/p",  where  re  stands  for  a  regular  expression, 
  to  Globally  search  for  the  Regular  Expression  and  Print  the 
  lines  containing  matches  to  it  There  are  two  other  variants, 
  fgrep  which  searches  only  for  fixed  strings  and  {egrep}  which 
  accepts  extended  REs  but  is  usually  the  fastest  of  the  three 
 
  Used  by  extension  to  mean  "to  look  for  something  by  pattern".
