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?

task_current_syscall

TASK_CURRENT_SYSCALL(9) 					   Machine State					   TASK_CURRENT_SYSCALL(9)

NAME

       task_current_syscall - Discover what a blocked task is doing.

SYNOPSIS

       int task_current_syscall(struct task_struct * target, long * callno, unsigned long args[6], unsigned int maxargs, unsigned long * sp,
				unsigned long * pc);

ARGUMENTS

       target
	   thread to examine

       callno
	   filled with system call number or -1

       args[6]
	   filled with maxargs system call arguments

       maxargs
	   number of elements in args to fill

       sp
	   filled with user stack pointer

       pc
	   filled with user PC

DESCRIPTION

       If target is blocked in a system call, returns zero with *callno set to the the call's number and args filled in with its arguments.
       Registers not used for system call arguments may not be available and it is not kosher to use struct user_regset calls while the system
       call is still in progress. Note we may get this result if target has finished its system call but not yet returned to user mode, such as
       when it's stopped for signal handling or syscall exit tracing.

       If target is blocked in the kernel during a fault or exception, returns zero with *callno set to -1 and does not fill in args. If so, it's
       now safe to examine target using struct user_regset get calls as long as we're sure target won't return to user mode.

       Returns -EAGAIN if target does not remain blocked.

       Returns -EINVAL if maxargs is too large (maximum is six).
