The code that you provided stops at line 8 with exit 1:
Code:
...
    printf("%s: %s\n", name, str1);         //puts() always adds newline at the end of the string
        //printf("%d\n", i); 
    i++;                                    //increment of record count
    if (i > 8) exit (EXIT_FAILURE);       //truncate the input file, need improved

If I remove that then I get a sgmentation fault.
In the code that you provided there are two mistakes, here is one correction
Code:
typedef struct {
    char ID[32];
...

Further, you mix up line numbers with record numbers.
If variable i is supposed to increment with every record starting with "Sample Name" then you can have
Code:
    if (strstr(name, "Sample Name") != NULL) {
        i++;                                    //increment of record count
        strcpy(record[i].ID, name);
    }

and no increment for every line!
And in order to start with index 0 the initialization should be
Code:
    static int i = -1;           //initialize counter

viewperl

VIEWPERL(1)							   User Commands						       VIEWPERL(1)

NAME

       viewperl - quickly view syntax highlighted Perl code

SYNOPSIS

       viewperl [OPTION]... FILE...

DESCRIPTION

       View a Perl source code file, syntax highlighted.

       -c, --code=CODE
	      view CODE, syntax highlighted

       -l, --lines
	      display line numbers

       -L, --no-lines
	      supress display of line numbers (default)

       -m, --module=FILE
	      consider FILE the name of a module, not a file name

       -n, --name
	      display the name of each file (default)

       -N, --no-name
	      supress display of file names (implied by --no-reset)

       -p, --pod
	      display inline POD documentation (default)

       -P, --no-pod
	      hide POD documentation (line numbers still increment)

       -r, --reset
	      reset formatting and line numbers each file (default)

       -R, --no-reset
	      supress resetting of formatting and line numbers

       -s, --shift=WIDTH
	      set tab width (default is 4)

       -t, --tabs
	      translate tabs into spaces (default)

       -T, --no-tabs
	      supress translating of tabs into spaces

       --help display this help and exit

       Note that module names should be given as they would appear after a Perl `use' or `require' statement.  `Getopt::Long', for example.

       Each string given using -c is considered a different file, so line number and formatting resets will apply.
