Creating textfile from arguments

Hi all

I'm new to this forum and I really hope someone can help me out with a (for you guys) fairly easy question.

I want to have a script that takes 1-14 arguments, all numbers 1-14, say

myscript 1 3 4 5 7

what the script shall do is basically generare a textfile that contains 16 instances of a string with each argument appended, e.g.

Code:
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp1
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp3
hejhopp4
...
etc

Does anyone have a clue?

Regards
Tobbe

Is this homework/classroom stuff?

Example with ksh as a start:
Code:
#!/usr/bin/ksh

STR=hejhopp
C=1
MAX=16

for E in $@; do
        while [ $C -le $MAX ]; do
                let C+=1
                print $STR$E
        done
        C=1
done

You can check the input with case/esac. Try it out and ask if you get stuck.

With ksh93:
Code:
#!/usr/bin/ksh93
maxargs=14
strng=hejhopp
(( $# > maxargs )) && { echo "More than $maxargs arguments not allowed"; exit 2; }
for i in "$@"
do
 for((j=1;j<=16;j++))
 do
  print "$strng$i"
 done
done

Hi again

Thanks a million for your input. And no, its not for school, I finished that 10 years ago.

I'm not used to scripting like this, that's the sad truth.

I realized that I need to alter the script a bit. When the argument is 10 or above, the string shall change from comp10 to comp1 as the output shall be (depending on the arguments) comp101, comp102, .... , comp110, comp111 etc.

I tried myself, see below (I used your code as base elixir_sinari)

Code:
#!/usr/bin/ksh93
maxargs=14
#strng=comp10
(( $# > maxargs )) && { echo "More than $maxargs arguments not allowed"; exit 2; }
for i in "$@"
 do
  for((j=1;j<=16;j++))
   do
    if [ ${i} < 10 ]
      then
      strng=comp10
      else
      strng=comp1
    fi
    printf "$strng$i"
    printf "\n"
   done
done

However, I get the following error:

Code:
...
compc13
myscript2: line 9: 10: No such file or directory
...

Sorry for being a total noob on this, but can anyone see what I'm doing wrong?
