Shell Programming and Scripting

I have one file of numbers

4
5
2
...

And another file of strings

aaaaa bbbbb
ccccc ddddd
eeeee ffffff
...

I'd like to print the stings from each line in reverse order with some decoration the number of times listed in the first file

such as:

Yeah bbbbb aaaaa
Yeah bbbbb aaaaa
Yeah bbbbb aaaaa
Yeah bbbbb aaaaa
Yeah ddddd ccccc
Yeah ddddd ccccc
Yeah ddddd ccccc
Yeah ddddd ccccc
Yeah ddddd ccccc
Yeah fffff eeeee
Yeah fffff eeeee


I'm trying with:

awk '
NR==FNR{
a[NR]=$0
next
}
{
for(i=1;i<NR;i++)
print "Yeah", $2,$1
}
' filenumbers filestrings > outfile

This isn't working.

Thanks for your help

It is unclear what the file with numbers is for. How does "Yeah" derive from the number "5" or the number "4"?

Sorry. The number in line one of the file with numbers is the number of times I'd like to print out the manipulation of the strings in line one from the file with the strings. The 'Yeah' is an example of appended text that doesn't appear in the file with strings that I'd like to add to each line of the outfile.

For example if '5' appears in line one of the file with numbers and '2' appears in line 2 of the file with numbers I'd like to print out the modified stings in line one of the file with strings 5 times followed by the modified strings from line 2 two times

File with numbers:
5
2

_____

File with strings:
aa bb
cc dd
_____

Example outfile:

1) bb aa
2) bb aa
3) bb aa
4) bb aa
5) bb aa
1) dd cc
2) dd cc

Thank you.

Your awk script never uses a[index] for anything after declaring it. You probably want the loop condition to read i <= a[NR]

For what it's worth, I don't think the original problem description was unclear at all.

Code:

awk '{
   if (NR != FNR) {
      for (i = 1; i <= f[FNR]; ++i) {
         printf("Yeah")
         for (j = NF; j >= 1; --j)
            printf(" %s", $j)
         print ""
      }
   } else
      f[NR] = $1
}' filenumbers filestrings

Thank you so much that worked great. As you can tell I'm very new to this.

One thing to avoid is switching the files LOL

awk '{
if (NR != FNR) {
for (i = 1; i <= f[FNR]; ++i) {
printf("Yeah")
for (j = NF; j >= 1; --j)
printf(" %s", $j)
print ""
}
} else
f[NR] = $1
}' filestrings filenumbers >out

and walk away...

Good way to fill up your drive
