Could any one help me to add entry at the end of the line.
This is linux os.
Below is the contents of the file /boot/grub2/grub.cfg
### BEGIN /etc/grub.d/10_linux ### menuentry 'Red Hat Enterprise Linux Server (3.10.0-327.el7.x86_64) 7.2 (Maipo)' --class red --class gnu-linux --class gnu --class os --unrestricted $menuentry_id_option 'gnulinux-3.10.0-327.el7.x86_64-advanced-75a4fe9b-ade6-4db0-a19c-e2dce64b4f2f' { load_video set gfxpayload=keep insmod gzio insmod part_msdos insmod xfs set root='hd0,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1 --hint='hd0,msdos1' 0ee3bceb-d7b7-4e56-ae16-a17ed5f395ea else search --no-floppy --fs-uuid --set=root 0ee3bceb-d7b7-4e56-ae16-a17ed5f395ea fi linux16 /vmlinuz-3.10.0-327.el7.x86_64 root=UUID=75a4fe9b-ade6-4db0-a19c-e2dce64b4f2f ro crashkernel=auto rhgb quiet LANG=en_US.UTF-8 initrd16 /initramfs-3.10.0-327.el7.x86_64.img } menuentry 'Red Hat Enterprise Linux Server (0-rescue-3b0570b9c0c44fd7b8426ed7d80f55ff) 7.2 (Maipo)' --class red --class gnu-linux --class gnu --class os --unrestricted $menuentry_id_option 'gnulinux-0-rescue-3b0570b9c0c44fd7b8426ed7d80f55ff-advanced-75a4fe9b-ade6-4db0-a19c-e2dce64b4f2f' { load_video insmod gzio insmod part_msdos insmod xfs set root='hd0,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1 --hint='hd0,msdos1' 0ee3bceb-d7b7-4e56-ae16-a17ed5f395ea else search --no-floppy --fs-uuid --set=root 0ee3bceb-d7b7-4e56-ae16-a17ed5f395ea fi linux16 /vmlinuz-0-rescue-3b0570b9c0c44fd7b8426ed7d80f55ff root=UUID=75a4fe9b-ade6-4db0-a19c-e2dce64b4f2f ro crashkernel=auto rhgb quiet initrd16 /initramfs-0-rescue-3b0570b9c0c44fd7b8426ed7d80f55ff.img }
I need to add entry at the end of the line “text1” and “text2”.
linux16 /vmlinuz-3.10.0-327.el7.x86_64 root=UUID=75a4fe9b-ade6-4db0-a19c-e2dce64b4f2f ro crashkernel=auto rhgb quiet LANG=en_US.UTF-8 text1 text2
after edit my file should look like:

With sed expression:
sed '~linux16 /vmlinuz-3.10.0-327.el7.x86_64~{s/$/ text1 text2/;}' /boot/grub2/grub.cfg
