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)
what will the cmd below do?
ls *.3
1 members mentions that to seek all permutations and combinations of the mp3 extension ill have to use curly braces, {} and not, .
what then will do? (13 Replies)
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.

I'm trying to make a small script to see if you say a specific word, in bash.
Here is my code so far :

ffi_prep_closure
ffi_prep_closure(3) BSD Library Functions Manual ffi_prep_closure(3)NAME
ffi_prep_closure -- Prepare a ffi_closure for execution.
SYNOPSIS
#include <ffi/ffi.h>
ffi_status
ffi_prep_closure(ffi_closure *closure, ffi_cif *cif, void (*fun)(ffi_cif*,void*,void**,void*), void *user_data);
DESCRIPTION
closure is prepared to execute fun. cif contains information describing the data types, sizes and alignments of the arguments to and return
value from the function that will be called from fun, and must be initialized with ffi_prep_cif before it is used with ffi_prep_closure.
user_data may point to additional data to be used in fun. If no additional data is needed, user_data may be NULL. When closure is invoked,
fun is called with cif, an array of pointers to arguments, a pointer to a return value, and user_data.
Some architectures do not allow the execution of data by default. In such cases, it is necessary to manually alter the permissions of the
page that contains closure prior to its execution.
RETURN VALUES
Upon successful completion, ffi_prep_closure returns FFI_OK. If the ABI specified in cif does not refer to a valid ABI, FFI_BAD_ABI will be
returned. Available ABIs are defined in <ffi/ppc-ffitarget.h> and <ffi/x86-ffitarget.h>.
EXAMPLES
#define MACOSX // for fficonfig.h on Darwin
#include <ffi/ffi.h>
#include <sys/mman.h> // for mmap()
unsigned char
foo(unsigned int, float);
static void
foo_closure(ffi_cif*, void*, void**, void*);
int
main(int argc, const char **argv)
{
ffi_cif cif;
ffi_closure *closure;
ffi_type *arg_types[2];
ffi_arg result;
ffi_status status;
// 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;
// Allocate a page to hold the closure with read and write permissions.
if ((closure = mmap(NULL, sizeof(ffi_closure), PROT_READ | PROT_WRITE,
MAP_ANON | MAP_PRIVATE, -1, 0)) == (void*)-1)
{
// Check errno and handle the error.
}
// 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.
}
// Prepare the ffi_closure structure.
if ((status = ffi_prep_closure(closure, &cif, foo_closure, NULL)) != FFI_OK)
{
// Handle the ffi_status error.
}
// Ensure that the closure will execute on all architectures.
if (mprotect(closure, sizeof(closure), PROT_READ | PROT_EXEC) == -1)
{
// Check errno and handle the error.
}
// The closure is now ready to be executed, and can be saved for later
// execution if desired.
// Invoke the closure.
result = ((unsigned char(*)(float, unsigned int))closure)(42, 5.1);
// Free the memory associated with the closure.
if (munmap(closure, sizeof(closure)) == -1)
{
// Check errno and handle the error.
}
return 0;
}
// Invoking the closure transfers control to this function.
static void
foo_closure(ffi_cif* cif, void* result, void** args, void* userdata)
{
// Access the arguments to be sent to foo().
float arg1 = *(float*)args[0];
unsigned int arg2 = *(unsigned int*)args[1];
// Call foo() and save its return value.
unsigned char ret_val = foo(arg1, arg2);
// Copy the returned value into result. Because the return value of foo()
// is smaller than sizeof(long), typecast it to ffi_arg. Use ffi_sarg
// instead for signed types.
*(ffi_arg*)result = (ffi_arg)ret_val;
}
// The closed-over function.
unsigned char
foo(unsigned int x, float y)
{
unsigned char result = x - y;
return result;
}
