using awk to modify field with condition












0














INPUT



New,9,1

Old,11,0


OUTPUT



New,09,1

Old,11,0


I would like to append to filed number 2 after first , in case if it's single digit so i would like to add 0 before the digit as the output shown.



I were able to achieve that using awk but i lost , as separator.



using the following command 



awk -F ',' '{if(length($2)==1)$2="0"$2;print $0}' inputfile





awk sed regular-expression

  • a small change in your awk command will do the needful awk -F ',' 'BEGIN { OFS=","};{if(length($2)==1)$2="0"$2;print $0}' Using OFS will ensure that the commas are printed

            Boot-repair Failure: Unable to locate package grub-common:i386

            Image
            0 I am on a system dual-booting Windows and Debian (usually using the latter), and a recent Windows update appears to have wreaked havoc on the Debian boot system. I managed to boot Windows again, but not Linux. Following online suggestions, I created a Live USB of Ubuntu, and booted from that. Then I have installed and run the boot-repair utility. The utility instructs me to type several lines including sudo chroot "/mnt/boot-sav/sda6" apt-get purge -y grub*-common grub-common:i386 To which I receive the error E: Unable to locate package grub-common:i386 I am given to understand the issue may have to do with having UEFI vs BIOS (I believe I have UEFI), but do not understand this well. In any case I have subsequently run the boot-repair BootInfo Summary utility which created the following file h...
