using awk multiplication
Suppose i have a file A
1*2*3*4
2*4*4*22
and second file B
2*3*4*5
4*4*6*7
By multiplying file A by file B that is file A by first column in file B respectively
output shud be
2*6*12*20
8*16*24*154
my code is
[CODE][/
for a in A
do
for FILE in B
do
awk 'NR==FNR {
x[FNR] =$1
next
}
{for (f=1;f<=NF;f++)
$f*= x[FNR]
} 1' OFS='*' FS='*' $a $FILE >file_output
done
done
CODE]
then output was
2*3*4*5
8*8*12*14

--compress[=no,xz,gz,lzo]
Compress GRUB files using the specified compression algorithm.
--directory=DIR
Use images and modules in DIR.
--grub-mkimage=FILE
Use FILE as grub-mkimage(1). The default is /usr/bin/grub-mkimage.
--rom-directory=DIR
Save ROM images in DIR.
--xorriso=FILE
Use FILE as xorriso.
--grub-glue-efi=FILE
Use FILE as grub-glue-efi(3).
--grub-render-label=FILE
