awk printing redirection in awk script

[alfie002]

Hello All,

I thought I had this working, but it doesn't want to redirect the output to a series of files.

Background is: I have a text file from which I want to extract 2 variables, $4 and $6. For each instance of $4 I want to print the contents of the variables $4 and $6 to an external file named using the $4 variable.

I have the bulk of the script working, but I cannot get the script to generate and print the contents of the $4 and $6 variables to the individual files..

I have attached a copy of the code below.

BEGIN {
}
{
contact_name=$4
contact_number=$6
file_name=$4".vcf"
{ print "N:"$4"\n" "TEL;CELL;VOICE:"$6 > $file_name }
}
END {
}

Any help would be appreciated.

Regards

Alf

PS: I am running awk with the -f parameter and submitting the source data file on the command line when the script is run.

Replace this:
> $file_name
By this:
> file_name

Seems you don't need the contact_XXX variables, so the whole awk program could be as simple as this:
{ print "N:"$4"\nTEL;CELL;VOICE:"$6 > $4".vcf" }


Hope This Helps, PH.

Hello there,

many thanks for your reply. I have quickly tried this as follows and the following error is generated.

awk '{ print "N:"$4"\nTEL;CELL;VOICE:"$6 > $4".vcf" }' PhoneBook.ncc

awk: cmd. line:1: (FILENAME=PhoneBook.ncc FNR=1) fatal: expression for `>' redirection has null string value

It doesn't like the redirection. I am running this script of Redhat Linux, but surely this shouldn't be a problem. in terms of compatibility ??

Thanks and regards

Alf

And this ?
awk 'NF>5{print "N:"$4"\nTEL;CELL;VOICE:"$6 > $4".vcf"}' PhoneBook.ncc

Hope This Helps, PH.

OK, works on gawk, not on nawk.
You may try this instead:
awk 'NF>5{out=$4".vcf";print "N:"$4"\nTEL;CELL;VOICE:"$6 > out}' PhoneBook.ncc

Hope This Helps, PH.

Hi

This is a usual error when reading, but is possible to be the same. Try to enclose the expression between parenthesis :

{ print "N:"$4"\nTEL;CELL;VOICE:"$6 > [red]([/red]$4 ".vcf"[red])[/red] }
