How to add text to a file after every 10 lines ? 1

[lotamoka]

I have file like this
libv lib11 BW1079 rem=bulk checkl=no force=yes
libv lib11 BW1560 rem=bulk checkl=no force=yes
libv lib11 BW1924 rem=bulk checkl=no force=yes
libv lib11 BW1947 rem=bulk checkl=no force=yes
libv lib11 BW1951 rem=bulk checkl=no force=yes
libv lib11 BW1960 rem=bulk checkl=no force=yes
libv lib11 BW1965 rem=bulk checkl=no force=yes
libv lib11 BW1968 rem=bulk checkl=no force=yes
libv lib11 BW2013 rem=bulk checkl=no force=yes
libv lib11 BW2021 rem=bulk checkl=no force=yes
libv lib11 BW1079 rem=bulk checkl=no force=yes
libv lib11 BW1560 rem=bulk checkl=no force=yes
libv lib11 BW1924 rem=bulk checkl=no force=yes
libv lib11 BW1947 rem=bulk checkl=no force=yes
libv lib11 BW1951 rem=bulk checkl=no force=yes
and i want to add following text after 10th line

echo "Please Remove the Tapes from the Library"
echo "Press enter when the tapes have been removed\c"
read
sleep 2
echo " Ejecting the next 10 Tapes"

Is there any way we can do with awk ?

Hi

awk '{print}!(NR%10){print "all the text you want"}' /input/file > /output/file

Hi Feherke
What would be above command when text to be added is from another file ?
Your help very much appreciated.

Hi

A brutal way :

awk '{print}!(NR%10){system("cat [green][i]otherfile[/i][/green]")}' /input/file > /output/file

Hi

Ok, here is the nice way too :

awk 'FNR==NR{s=s $0 RS;next}{print}!(FNR%10){print s}' otherfile /input/file > /output/file

Hi

awk '
{                      [gray]# do it for all input records[/gray]
  [b]print[/b]                [gray]# print the current record *[/gray]
}
!(NR%10) {             [gray]# do it if the record number is divisible with 10 **[/gray]
  system([i]"cat test1"[/i])  [gray]# execute external command[/gray]
}
' test

[gray]*[/gray] - [tt]print[/tt] is the same as [tt]print $0[/tt]
[gray]**[/gray] - [tt]!(NR%10)[/tt] is the same as [tt]NR%10==0[/tt]
