modify and rename file

[Josewr]

I need to modify a file and rename it. Tried:

awk -f modfile oldname new=newfile.fmt
(Tried also: awk -f modfile oldname new="newfile.fmt")

and modfile has lines such as

{print " mod1 " > new}
{print " mod2 " > new}

The modfile works if I change the lines to read:

{print " mod1 " > "newfile.fmt"}
{print " mod2 " > "newfile.fmt"}
rather then passing it from the command line

Thanks

Hi

Just an idea. Specify the new name as [tt]-v new="newfile.fmt"[/tt]. As you wrote it, the [tt]new[/tt] variable will be created after the BEGIN blocks, but if you specify with the [tt]-v[/tt], will be created before the execution of BEGINs.

Sorry, but I had tried that also. I was just trying to simplify the Posting. This are the important lines on the program look like:

BEGIN {getline
print $0 > new}

{if (length($2) >= 76){
{print "-- * " > new}
{print "-- * 8/3/05 Jose Changed to New Specs, 18 May 2005. " >new}
{print "-- * " > new}
{print "-- * " > new}
}}

{print $0 > new}

And the command line:

gawk -f ModifyFile1.awk OldFileName.fmt -v new="NewFile.fmt"

I get the following error:

gawk: ModifyFile1.awk:3: (FILENAME=OldFileName.fmt FNR=1) fatal: expression for `>' redirection has null string value

Therefore, is not reading the variable on the first line.
I may have more {} than I need. I am new at this.
Thanks.

Try this:
gawk -v new="NewFile.fmt" -f ModifyFile1.awk OldFileName.fmt

Hope This Helps, PH.
