Reading 2 input files but not getting expected value 1

[pdtak]

I'm reading 2 input files but not getting expected value.
I should get an alpha value on file_1_data[*] but not getting any.

Please help.

>cat test6.sh
awk '
FILENAME==ARGV[1] { file_1_data[$1]=$0; print "----- 1 Line " NR " -----" $1; next }
FILENAME==ARGV[2] { file_2_data[$1]=$0; print "----- 2 Line " NR " -----" $1; next }
END {
# do actual data processing here
print "----- Line " NR " -----"
print "----- file_1_data[1] " file_1_data[1]
print "----- file_1_data[2] " file_1_data[2]
print "----- file_1_data[3] " file_1_data[3]

If you want to look up the data by line numbers then you need to index the original array by line numbers, i.e. use file_1_data[FNR]=$0 insetad of file_1_data[$1]=$0.

Also, consider using a for loop to print:

    for (i=1; i<=10; i++) {
        print "-----   file_1_data["i"] "  file_1_data[i]
    }

Alternativly:

awk '
    FILENAME==ARGV[1] { file_1_data[$1]=$0; print "----- 1 Line " NR " -----" $1; next }
    FILENAME==ARGV[2] { file_2_data[$1]=$0; print "----- 2 Line " NR " -----" $1; next }
    END {
        # do actual data processing here
        print "----- Line " NR " -----"
        for(i in file_1_data)
          print "-----   file_1_data["i"] "  file_1_data[i]
        for(i in file_1_data)
          print "-----   file_2_data["i"] "  file_2_data[i]
        print "\n"
    }
' infile1 infile2
