Question

AWK syntax problem.

Answer 1

I am writing to write a AWK command line to take a line from a file (X.dat) and transfer it to another document (Y.dat) based the number in column 5, I am using a loop to separate the lines and use the variable in my condition.

The code looks like this:

for j in 3.0 4.0 5.0 6.0 6.5 7.0 8.0 9.0
do
awk "$5==${j} {print $0}" X.dat >Y.dat.

The error message is:
awk: =='3.0' {print}
awk: ^ syntax error
awk: =='4.0' {print}
awk: ^ syntax error
awk: =='5.0' {print}
awk: ^ syntax error
awk: =='6.0' {print}
awk: ^ syntax error
awk: =='6.5' {print}
awk: ^ syntax error
awk: =='7.0' {print}
awk: ^ syntax error
awk: =='8.0' {print}
awk: ^ syntax error
awk: =='9.0' {print}
awk: ^ syntax error

Answer 2

Issue fixed. It was a matter of global and local variables. The fixed code was the following:

for j in 3.0 4.0 5.0 6.0 6.5 7.0 8.0 9.0
do
awk "\$5==${j} {print $0}" X.dat >Y.dat.
