Most versions of grep can handle a file of patterns, so that standard *nix utlities can be used:
Producing:
The files are filtered for the lines that contain strings of interest. Then, in order to count with uniq, we need to sort the result.
If you need better filtering, you may need to change the patterns in the strings file, or -- in some versions of grep -- use the "word" option "-w".
Adjust as necessary for your environment according to your man pages ... cheers, drl

Hi,
I have a list of zipped files. I want to grep for a string in all files and get a list of file names that contain the string. But without unzipping them before that, more like using something like gzcat.

strtok
STRTOK(3) BSD Library Functions Manual STRTOK(3)NAME
strtok, strtok_r -- string tokens
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h>
char *
strtok(char * restrict str, const char * restrict sep);
char *
strtok_r(char *str, const char *sep, char **lasts);
DESCRIPTION
The strtok() function is used to isolate sequential tokens in a nul-terminated string, str. These tokens are separated in the string by at
least one of the characters in sep. The first time that strtok() is called, str should be specified; subsequent calls, wishing to obtain
further tokens from the same string, should pass a null pointer instead. The separator string, sep, must be supplied each time, and may
change between calls.
The strtok() function returns a pointer to the beginning of each subsequent token in the string, after replacing the separator character
itself with a NUL character. Separator characters at the beginning of the string or at the continuation point are skipped so that zero
length tokens are not returned. When no more tokens remain, a null pointer is returned.
The strtok_r() function implements the functionality of strtok() but is passed an additional argument, lasts, which points to a user-provided
pointer which is used by strtok_r() to store state which needs to be kept between calls to scan the same string; unlike strtok(), it is not
necessary to limit tokenizing to a single string at a time when using strtok_r().
EXAMPLES
The following will construct an array of pointers to each individual word in the string s:
#define MAXTOKENS 128
char s[512], *p, *tokens[MAXTOKENS];
char *last;
int i = 0;
snprintf(s, sizeof(s), "cat dog horse cow");
for ((p = strtok_r(s, " ", &last)); p;
(p = strtok_r(NULL, " ", &last)), i++) {
if (i < MAXTOKENS - 1)
tokens[i] = p;
}
tokens[i] = NULL;
That is, tokens[0] will point to "cat", tokens[1] will point to "dog", tokens[2] will point to "horse", and tokens[3] will point to "cow".
SEE ALSO index(3), memchr(3), rindex(3), strchr(3), strcspn(3), strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3)STANDARDS
The strtok() function conforms to ANSI X3.159-1989 (``ANSI C89''). The strtok_r() function conforms to IEEE Std 1003.1c-1995 (``POSIX.1'').
BUGS
The System V strtok(), if handed a string containing only delimiter characters, will not alter the next starting point, so that a call to
strtok() with a different (or empty) delimiter string may return a non-NULL value. Since this implementation always alters the next starting
point, such a sequence of calls would always return NULL.
