[FUG-BR] grep

[Ricardo A. Reis]

Celso,

   O grep e' pobre de regexp mais isso ele faz hehe

man grep
------
   -e pattern_list Specifies one or more patterns  to  be  used
                     during  the  search  for  input. Patterns in
                     pattern_list must be separated by a  NEWLINE
                     character.  A  null pattern can be specified
                     by  two  adjacent  newline   characters   in
                     pattern_list.  Unless the -E or -F option is
                     also specified, each pattern is treated as a
                     basic  regular  expression.  Multiple -e and
                     -f options are accepted by grep. All of  the
                     specified  patterns  are  used when matching
                     lines,  but  the  order  of  evaluation   is
                     unspecified.

Ex.

grep -e ricardo -e root /etc/passwd
root:x:0:0:Super-User:/:/bin/ksh
ricardo:x:100:100:Ricardo A. Reis:/export/home/ricardo:/usr/bin/bash
