AWK script

siba.s.nayak · #1 (**permalink**) 11-18-2008

I have written an awk script. If i run it from command prompt with awk -f then it working fine. but when run the same statements in a script and named file as a1.awk and tried to run it awk -f a1.awk temp.txt > temp2.txt I doesn't work.

The script is like this
awk -F'|' '
BEGIN{

}

{ if($4=="1"){
print "*********" a[$3]

if( a[$3] < $6 ){
a[$3]=$7;
b[$3]=$2;
}
else if ( a[$3] == $7 ){
if( $9 == 1 ){
b[$3]=$2;
}
}
}
next;

}
END {
for ( x in b ) {
print x "|" b[x]
}
}

' temp1.txt> /var/tmp/temp2.txt

The above things works fine but when I put same thing in a script like
a1.awk
and run the script awk -f a1.awk temp1.txt > temp2.txt
No output is written to output file.
Please help me.

You list the working code, but not the code that's broken

makes it a little hard to help.

I'll provide a simplified, working, example... maybe the problem will pop out at you?

My input file (called z.in):

Code:

10,ten
3,three
1,one

From the command line:

Code:

cat z.in |awk '{FS=","; sum += $1} END {print sum}'
13

Putting the awk junk in a script. Contents of z.awk:

Code:

{FS=","; sum += $1} END {print sum}

and the result:

Code:

awk -f z.awk z.in
13

Putting it all in a script. Contents of z.ksh:

Code:

#!/bin/ksh

awk -f z.awk z.in

And running it:

Code:

./z.ksh
13

Place the code in a script, make it executable and run it as:

Code:

./scriptname

The script should look like:

Code:

#!/bin/sh

awk -F'|' '
BEGIN{... }
}
.
# Your code
.
{ 
' temp1.txt> /var/tmp/temp2.txt
