egrep -- Extended pattern search

egrep [-Abcefhily] [pattern] [file ...]

Options:
     -A        Build error list for interactive editing using MicroEMACS, like
               -A option to the cc command
     -b        Each output line has block number of match
     -c        Print only a count of the matching lines
     -e        Next argument is pattern
     -f        Next argument is file with one pattern per line
     -h        Suppress printing of file names on matched lines
     -i        Ignore case when matching alphabetic characters in pattern
     -l        Print only names of files containing matches
     -n        Print line number of file with each matched line output
     -s        Suppress output, just return status
     -v        Negate the sense of match
     -y        Lower-case letters in pattern match upper- and lower-case

The pattern is a pattern roughly like that found in ed.  If no file is
specified, stdin is read.  egrep is like grep -a, but is an order of magnitude
faster.
