UNIX for Dummies Questions & Answers

Yep, correct!

OKay, so I grunched this thread other than the first few posts.
In there no one mentioned how this line here:

Code:

{printf "grep %s junk.all.dat | awk '$4<=%s{print $1, $2, $3, $4, $5}' | wc -l >> fitnumb.dat\n"}

Is missing some arguments. At any rate... The %s are formatting strings that printf interprets to mean "print the associated argument as a string".

In this command, however, there are no arguments to printf.
On my system, this doesn't even work.

But making some modifications and attempting to stick with the original intent, I got this to work:

Code:

2158 -> cat a.awk
{
printf( "grep %s junk.all.dat | awk '$4 <= %s{print $1, $2, $3, $4, $5}' | wc -l >> fitnumb.dat\n",
  $1, $2 );
}

2159 -> date | awk -f a.awk
grep Mon junk.all.dat | awk '$4 <= May{print $1, $2, $3, $4, $5}' | wc -l >> fitnumb.dat

I'm probably late to the game -- but HTH.
