I have two files as input with data that looks like this:
file1.txt
Code:
1
2
3
4
file2.txt
Code:
a,aa
b,bb
c,cc
d,dd
e,ee
f,ff
instead of me doing 2 while loops to get the combinations
Code:
while read line_file1
do
while read line_file2
do
1stpos="$(echo $line_file2 | cut -d "," -f1)"
2ndpos="$(echo $line_file2 | cut -d "," -f2)"
printf "%-20s%-20s%-20s" ${1stpos} ${2ndpos} $(line_file1) >> output.txt
done < file2.txt
done < file1.txt
The output should look like this:
Code:
a aa 1
b bb 1
c cc 1
d dd 1
e ee 1
f ff 1
a aa 2
b bb 2
c cc 2
d dd 2
...
<-- assuming that the output file is in a fixed length format since columns are not aligned
can this be done using awk? or sed? to speed up the process of looping; because in reality, data is could be very enormous and could lead to performance issues. please help.... thanks!
