awk FNR Question 1

[johngiggs]

I am attempting to skip lines 1-6 in a file so that they are not parsed by my awk script. I attempted to use every variation of FNR and next that I could think of, however I couldn't get it to work. Below is my very basic awk script.

BEGIN{printf ("%-17s %-10s %-15s %-15s %-10s %-8s\n", "Policy", "Type", "Stg Uni
t", "Vol Pool", "Priority", "Active")}
{printf ("%-17s %-10s %-15s%-15s %-10s %-8s\n", $1, $2, $3, $4, $7, $8)}

I tried using some of the examples below as the first line in the script, but nothing has worked thus far.

{if (FNR<6) next}

{FNR==6}

Any help would be greatly appreciated.

Thanks,

John

skip lines 1-6
BEGIN{printf ("%-17s %-10s %-15s %-15s %-10s %-8s\n", "Policy", "Type", "Stg Uni
t", "Vol Pool", "Priority", "Active")}
FNR>6{printf ("%-17s %-10s %-15s%-15s %-10s %-8s\n", $1, $2, $3, $4, $7, $8)}

Hope This Helps, PH.

PH,

Thank you for your suggestion, but that doesn't seem to work either. Does anyone have any other suggestions?

Thanks,

John

This works; I tested it.

BEGIN { fmt = "%-17s %-10s %-15s %-15s %-10s %-8s\n"
  printf fmt, "Policy", "Type", "Stg Unit",
    "Vol Pool", "Priority", "Active" }
FNR < 7 { next }
{ printf fmt, $1, $2, $3, $4, $7, $8 }

It must work, because that's the way Awk works.

FNR < 7 { next }

If the number of the record just read from the current file is less than 7, skip the rest of the code, jump to the top of the loop, and read the next record.

PH,

I didn't realize that nawk was installed on the server, so I tested the script with nawk and it worked fine. Have a star!!

futurelet,

I believe your solution only works with nawk as well.

Thank you both for your help.
