Question

For this Linux script, answer the questions following it:

# Sort lines 7 - 26 of the file

BEGIN {
idx = 1;
while (getline line<"makefile" ) {
data[idx] = line;
idx++;
}
for (idx2 = 7; idx2 <= 26; idx2++) {
data2[idx2 - 6] = data[idx2];
}
count = asort(data2);
for (idx3 = 1; idx3 < 7; idx3++) {
print data[idx3];
}
for (idx3 = 1; idx3 <= 20; idx3++) {
print data2[idx3];
}
for (idx3 = 27; idx3 < idx; idx3++) {
print data[idx3];
}

}

1) What variables are used by the script? If no variables are used then write "none"

2) How many pattern blocks, including the BEGIN and END blocks, are included in the script? If no blocks are used then write "none".

3) List the awk functions used in the script, and describe the purpose of each function. If no functions are used then write "none".

4) Are there any errors in the script? Does the script accomplish the task that was intended?

yes see attachment , to perform this script successfully it need full script as this has only 7-26 lines

5) Are there any improvements that should be made to the script? What are they?
seems sorting the data to an array , from seeing this lines logic seems ok
