You can do something like that :
Code:
while read student_id && read student_account && read student_info
do
   (( student_count++ ))
   echo "student #$student_count id=$student_id account=$student_account info=$student_info"
done < cat.txt
echo "Final student count: $student_count"

Input file:
Code:
11
12
+380486461001
12
13
+380486461002
13
14
+380486461003

Output:
Code:
student #1 id=11 account=12 info=+380486461001
student #2 id=12 account=13 info=+380486461002
student #3 id=13 account=14 info=+380486461003
Final student count: 3

AMC-EXPORT(1)						       Auto Multiple Choice						     AMC-EXPORT(1)

NAME
AMC-export - exports marks for AMC multiple choice exams. SYNOPSIS
auto-multiple-choice export --data project-data-dir --module module --fich-noms students-list.csv [--noms-encodage list-encoding] --o output-file DESCRIPTION
The AMC-export.pl command exports marks from an Auto Multiple Choice exam. --data project-data-dir gives the directory where data files are (see for example AMC-prepare(1)). --module module selects a module for export. See below for the modules included in the AMC standard distribution. --fich-noms students-list.csv sets the students list file. --noms-encodage list-encoding selects an encoding for file students-list.csv (default is utf-8). --o output-file gives the output file name. --option-out options gives an option for selected module, in the form key=value (see below for possible options for each module). To specify multiple options, use --option several times. --sort sort-type sort the students names, depending on sort-type. If sort-type is l, use line number from students list file to sort. If sort-type is m, use mark (and name if marks are equal) to sort. If sort-type is i, use student number to sort. If sort-type is n, use name to sort (or line from students list if equal). --useall all if all is 0 or empty, only students with a scaned answer sheet appears in the output. If all is 1, all students in the students list appears in the output. MODULES
OpenDocument With "--module ods", an OpenDocument (for use by OpenOffice or LibreOffice for example) is produced. The following options are recognized: nom gives a name for the exam, to be written on the beginning of the sheet. code gives an short name for the exam, to be used as a tab name. columns sets the list of columns that are to be added to each student. Default value is student.key,student.name. stats with a true value, a table will be added with statistics for all questions. statsindic with a true value, a table will be added with statistics for all indicative questions. CSV With "--module CSV", a CSV file is produced. The following options are recognized: columns sets the list of columns that are to be added to each student. Default value is student.copy,student.key,student.name. decimal sets the decimal point (default is a dot). encodage sets the encoding to use for output (default is utf-8). separateur sets the character used between colums (default is a comma). entoure sets the character used to enclose strings (default is a double quote). ticked if not empty, additional columns (with "CHECKED:" prefix) are included to give all the checked boxes on all the sheets. This can be used by an external program to retrieve all the checked boxes when marks are not sufficient. Use value 01 to get 0;0;1;1;0 if boxes 3 and 4 are checked, and value AB to get CD if boxes 3 and 4 are checked. List With "--module List", a PDF file is produced with a list of marks for all students. The following options are recognized: pagesize The page size. Default value is a4. nom gives the name of the exam, to be printed at the top of the page. ncols The number of columns. Default value is 2. decimal sets the decimal point (default is a dot). AUTHORS
