If you want to count the number of lines on which one or more of these strings occur
Code:
for i in $(find /path/to/dir) ; do grep -E '(abc|cde)' ;done | wc -l

If you just want a count of files in which one of the strings occurs
Code:
for i in $(find /path/to/dir) ; do echo $i:$(grep -E '(abc|cde)') ;done |cut -d \: -f1|uniq| wc -l

NAME

       lookbib - find references in a bibliographic database

SYNOPSIS

       lookbib database

DESCRIPTION

       A  bibliographic reference is a set of lines, constituting fields of bibliographic information.	Each field starts on a line beginning with
       a `%', followed by a key-letter, then a blank, and finally the contents of the field, which may continue until the next line starting  with
       `%'.

       The lookbib utility uses an inverted index made by indxbib to find sets of bibliographic references.  It reads keywords typed after the `>'
       prompt on the terminal, and retrieves records containing all these keywords. If nothing matches, nothing is  returned  except  another  `>'
       prompt.

       It is possible to search multiple databases, as long as they have a common index made by indxbib(1).  In that case, only the first argument
       given to indxbib is specified to lookbib.

       If lookbib does not find the index files (the .i[abc] files), it looks for a reference file with the same name as the argument, without the
       suffixes.  It creates a file with a .ig suffix, suitable for use with fgrep (see grep(1)). lookbib then uses this fgrep file to find refer-
       ences.  This method is simpler to use, but the .ig file is slower to use than the .i[abc] files, and does not allow  the  use  of  multiple
       reference files.

FILES

       x.ia

       x.ib

       x.ic	index files

       x.ig	reference file

BUGS

       Probably all dates should be indexed, since many disciplines refer to literature written in the 1800s or earlier.
