Could you please try the following code.

Code:
$ cat check_count_first_row_check121.ksh
echo "enter week"
read week
echo ""
awk -vs1="$week" 'BEGIN{print s1} 1' check_count_first_row_check121

Output will as follows.

Code:
$ ksh check_count_first_row_check121.ksh
enter week
week1
 
week1
02.05.2014,apple,homeworbook,red pen,yellow
10.05.2014,cookies,language book,water pain,red
10.05.2014,carot,science,purple,green

Note: Where check_count_first_row_check121.ksh is the script name and check_count_first_row_check121 is the input file name.


Thanks,

Assuming that the whatever follows "week" is the line number, try:
Code:
#!/bin/ksh
 echo "enter week" 
read week 
line=$(echo $week | awk '$1 ~ /week/ {print $2}')
[ ! -z $line ] && sed -n "$line p" inputfile >>file
