I'm not sure I understand.

Could you not find a followed by b followed by c with just:
Code:
grep abc ...

-v negates results:

Code:
# cat file
abc
def
# grep abc file
abc
# grep -v abc file
def

-l (ell) will return the filename(s) with matches, instead of the matches themselves.

If you want only to extract the exact abc match (assuming that's variable, and thus useful), use the -o option, if available, otherwise switch to sed, or another tool.

Use the -q option if you only care about the result, and not the output.

zgrep

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)
