Pipe binary file matches grep results to file
I am using grep to match a pattern, but the output is strange.

Code:
$ grep -r -o "pattern" *

Gives me:
Code:
Binary file foo1 matches
Binary file foo2 matches
Binary file foo3 matches

To find the lines before/after, I then have to use the following on each file:
Code:
$ strings foo1 | grep -A1 -B1 "pattern"

How can I recursively perform this operation with strings? Or, is there an alternative?

zegrep

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME

     zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files

SYNOPSIS

     zgrep [grep-flags] [--] pattern [files ...]

     zegrep [grep-flags] [--] pattern [file ...]

     zfgrep [grep-flags] [--] pattern [file ...]

DESCRIPTION

     zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).

     The grep-flags and pattern arguments are passed on to grep(1).  If an -e flag is found in the grep-flags, zgrep will not look for a pattern
     argument.

     zegrep calls egrep(1), while zfgrep calls fgrep(1).

EXIT STATUS

     In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.

SEE ALSO

     egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
