Hi all,
I have a tar file and inside that tar file is a folder with additional tar.gz files. What I want to do is look inside the first tar file and then find the second tar file I'm looking for, look inside that tar.gz file to find a certain directory. I'm encountering issues by trying to... (1 Reply)
I would like to confirm my file.tar is been tar-ed correctly before I remove them. But I have very limited disc space to untar it.
Can I just do the listing instead of actual extract it? Can I say confirm folder integrity if the listing is sucessful without problem?
tar tvf file1.tar

Coming from this thread, just wondering if there is an option to check if the Tar of the files/directory will be without any file-errors without actually making the tar.
Scenario:
Let's say you have a directory of 20GB, but you don't have the space to make Tar file at the moment, and you want... (14 Replies)

alphasort
scandir(3) Library Functions Manual scandir(3)NAME
scandir, alphasort - Scans or sorts directory contents
LIBRARY
Standard C Library (libc.a)
SYNOPSIS
#include <sys/types.h> #include <sys/dir.h>
int scandir ( char *dir_name, struct dirent * (*name_list[ ]), int (*select) ( struct dirent *dir ), int (*compare) (
struct dirent **dir1, struct dirent **dir2 ) );
int alphasort ( struct dirent **dir1, struct dirent **dir2 );
PARAMETERS
Points to the directory name. Points to the array of pointers to directory entries. Points to a user-supplied function that is called by
the scandir() function to select which entries to include in the array. Points to a user-supplied function that sorts the completed
array. Points to a dirent structure. Points to a dirent structure.
DESCRIPTION
The scandir() function reads the directory pointed to by the dir_name parameter. It then uses the malloc() function to create an array of
pointers to directory entries. The scandir() function returns the number of entries in the array and, through the name_list parameter, a
pointer to the array.
The select parameter points to a user-supplied function that the scandir() function calls to select which entries to include in the array.
The selection routine is passed a pointer to a directory entry and returns a nonzero value for a directory entry that is included in the
array. If the select parameter is a null value, all directory entries are included.
The compare parameter points to a user-supplied function that is passed to the qsort() function to sort the completed array. If the compare
parameter is a null value, the array is not sorted.
The memory allocated to the array can be deallocated by freeing each pointer in the array, and the array itself, with the free() function.
The alphasort() function alphabetically compares the two dirent structures pointed to by the dir1 and dir2 parameters. This function can be
passed as the compare parameter to either the scandir() function or the qsort() function. A user-supplied subroutine may also be used.
RETURN VALUES
The scandir() function returns -1 if the directory cannot be opened for reading or if the malloc() function cannot allocate enough memory
to hold all the data structures. If successful, the scandir() function returns the number of entries found.
The alphasort() function returns the following values: Less than 0 (zero): The dirent structure pointed to by the dir1 parameter is lexi-
cally less than the dirent structure pointed to by the dir2 parameter. 0 (zero): The dirent structures pointed to by the dir1 parameter
and the dir2 parameter are equal. Greater than 0 (zero): The dirent structure pointed to by the dir1 parameter is lexically greater than
the dirent structure pointed to by the dir2 parameter.
