Which shell are you using?
As danmero states you will overwrite the output file for every grep.
Here is an alternative which uses find to expand the filenames.
I'm trying to figure out how to build a small shell script that will find old .shtml files in every /tgp/ directory on the server and delete them if they are older than 10 days...
The structure of the paths are like this:
/home/domains/www.domain2.com/tgp/
/home/domains/www.domain3.com/tgp/... (1 Reply)

Just a quick question:
if I want to do a comparison with a wildcard in a shell script, do i just use '*'? Heres what I have:
elif ; then
continue
but that doesnt evaluate right. It tries to compare against the literal '/apps*' instead of anything that begins with '/apps' (2 Replies)
Can someone please explain the wildcards in this. How is this recursive? When I put this in my terminal it recursively displayed everything.

ffi_call
ffi_call(3) BSD Library Functions Manual ffi_call(3)NAME
ffi_call -- Invoke a foreign function.
SYNOPSIS
#include <ffi/ffi.h>
void
ffi_call(ffi_cif *cif, void (*fn)(void), void *rvalue, void **avalue);
DESCRIPTION
The ffi_call function provides a simple mechanism for invoking a function without requiring knowledge of the function's interface at compile
time. fn is called with the values retrieved from the pointers in the avalue array. The return value from fn is placed in storage pointed to
by rvalue. cif contains information describing the data types, sizes and alignments of the arguments to and return value from fn, and must
be initialized with ffi_prep_cif before it is used with ffi_call.
rvalue must point to storage that is sizeof(long) or larger. For smaller return value sizes, the ffi_arg or ffi_sarg integral type must be
used to hold the return value.
EXAMPLES
#define MACOSX // for fficonfig.h on Darwin
#include <ffi/ffi.h>
#include <stdio.h>
unsigned char
foo(unsigned int, float);
int
main(int argc, const char **argv)
{
ffi_cif cif;
ffi_type *arg_types[2];
void *arg_values[2];
ffi_status status;
// Because the return value from foo() is smaller than sizeof(long), it
// must be passed as ffi_arg or ffi_sarg.
ffi_arg result;
// Specify the data type of each argument. Available types are defined
// in <ffi/ffi.h>.
arg_types[0] = &ffi_type_uint;
arg_types[1] = &ffi_type_float;
// Prepare the ffi_cif structure.
if ((status = ffi_prep_cif(&cif, FFI_DEFAULT_ABI,
2, &ffi_type_uint8, arg_types)) != FFI_OK)
{
// Handle the ffi_status error.
}
// Specify the values of each argument.
unsigned int arg1 = 42;
float arg2 = 5.1;
arg_values[0] = &arg1;
arg_values[1] = &arg2;
// Invoke the function.
ffi_call(&cif, FFI_FN(foo), &result, arg_values);
// The ffi_arg 'result' now contains the unsigned char returned from foo(),
// which can be accessed by a typecast.
printf("result is %hhu", (unsigned char)result);
return 0;
}
// The target function.
unsigned char
foo(unsigned int x, float y)
{
unsigned char result = x - y;
return result;
}
