Shell Programming and Scripting

I have a script part of which runs awk, I'd like to put a prompt within the awk section (something along the ines of continue), I can run the system() command e.g., system("clear") to clear the screen, however if I try something like system("echo enter to continue \c l read ans") I get nothing other than stty: tcgetattr: Not a typewriter (which also shows prior to clear but still clears screen), is there an alternative to do this ?

Code:

  printf("Enter to continue");
  getline ans < "-"

Thanks for the help, the Enter to continue prints correctly now, however there is no pause for input ?

Tried this on SUN

awk 'BEGIN{printf("Enter to continue: ");
getline ans < "-"
print ans
}'
Enter to continue: xxxxxxx
xxxxxxx


worked fine

Are you using Standard input for some other purpose? That would defeat this program.

If on Solaris, make sure to use 'nawk' (not 'awk')

nawk -f gefa.awk myInputFile

gefa.awk:

Code:

{
  printf("Enter to continue")
  getline ans < "-"
  printf("ans->[%s] line->[%s]\n", ans, $0)
}

Hi this is my code (I'm on AIX 5.3) if it's of any help;

awk -F, < $aclocat '
{
{ if ($1 ~ "Locat") {col1=$1 ; col2=$2 ; col3=$3 ; col4=$4 ; col5=$5 ; col6 = $6 ; col7 = $7 ; col8=$8 ; col9=$9}
if (substr($1,1,5) != "locat") {
if (mycount < 45)
{
printf "%-8s %-7s %-3s %-8s %-9s %-3s %-8s %-6s %-16s\n",$1,$2,$3,$4,$5,$6,$7,$8,$9
}
else {
mycount = 1
printf("Enter to continue");
getline ans < "-"


printf "%-8s %-7s %-3s %-8s %-9s %-3s %-8s %-6s %-16s\n",col1,col2,col3,col4,col5,col6,col7,col8,col9
}
}
mycount++
}
}'

try loosing the '<' on cli:

Code:

awk -F, $aclocat
