我的系统是centos7。我想比较备份和现有文件夹的ACL。
我注意到一个问题：while(1)
{
fprintf( logfile, "Looped!\n");
}
的结果不是按字母顺序排列的，因此用户fprintf( logfile, "Called as %s\n", executable );
fprintf( logfile, "Assigned pid %lu\n", pid );
fprintf( logfile, "Input File: %s\n", inputfilename );
fprintf( logfile, "Output File: %s\n", outputfilename );
fprintf( logfile, "Default BUFFER: %lu\n", BUFFER );
fprintf( logfile, "Crypt output sixe: %lu\n", CRYPT_OUTPUT_SIZE );
fprintf( logfile, "\n" );
/* Try to set up space for strings */
fprintf( logfile, "Attempting to allocate %lu chars(%u) for plaintext string...\n", BUFFER,sizeof(char) );
char *plaintext_string = (char *) calloc( BUFFER, sizeof(char) );
if( plaintext_string == NULL )
{
fprintf( logfile, "Errno %d; Error %s; Trying to allocate %lu chars(%u) for plaintext string\n",
errno, strerror(errno), BUFFER,sizeof(char) );
return(STRERROR);
}
fprintf( logfile, "Success; Now attempting to allocate %lu bytes for encrypted string...\n", CRYPT_OUTPUT_SIZE );
char *encrypted_string = (char *) calloc( CRYPT_OUTPUT_SIZE, sizeof(char) );
if( encrypted_string == NULL )
{
fprintf( logfile, "Errno %d; Error %s; Trying to allocate %lu chars(%u) for encrypted string\n",
errno, strerror(errno), (unsigned long) CRYPT_OUTPUT_SIZE, sizeof(char) );
return(STRERROR);
}
fprintf( logfile, "\n" );
fprintf( logfile, "Entering main loop\n" );
while( TRUE )
{
int res = fscanf( inputfile, "%s", plaintext_string );
if( res == EOF )
{
fprintf( logfile, "Reached EOF in %s; Breaking from loop\n", inputfilename );
break;
}
if( plaintext_string == NULL )
{
fprintf( logfile, "Errno %d; Error %s; String read in from %s was NULL\n", errno, strerror(errno), inputfilename);
free(plaintext_string);
free(encrypted_string);
fclose(logfile);
fclose(inputfile);
return(STRERROR);
}
strcpy( encrypted_string, crypt( plaintext_string, SALT ) );
if( encrypted_string == NULL )
{
fprintf( logfile, "Errno %d; Error %s; Encrypted string was NULL\n", errno, strerror(errno) );
free(plaintext_string);
free(encrypted_string);
fclose(logfile);
fclose(inputfile);
return(STRERROR);
}
fprintf( outputfile, "%s\n", encrypted_string );
/* Clear the strings so no data is held */
*plaintext_string = NULL;
*encrypted_string = NULL;
}
很难进行比较。
理想的字母顺序为：按文件夹名称字母顺序的文件夹列表。文件夹列表中的文件按文件名字母顺序排列。如下：
getfacl如何使beyond compare结果以文件夹名和文件名的字母顺序排列？
