How to run a .awk file?

Question

I am converting a CSV file into a table format, and I wrote an AWK script and saved it as my.awk. Here is the my script:

#AWK for test
awk -F , \'
    BEGIN {
           


        

Answer 1

The file you give is a shell script, not an awk program. So, try sh my.awk.

If you want to use awk -f my.awk life.csv > life_out.cs, then remove awk -F , ' and the last line from the file and add FS="," in BEGIN.

Answer 2

If you put #!/bin/awk -f on the first line of your AWK script it is easier. Plus editors like Vim and ... will recognize the file as an AWK script and you can colorize. :)

#!/bin/awk -f
BEGIN {}  # Begin section
{}        # Loop section
END{}     # End section

Change the file to be executable by running:

chmod ugo+x ./awk-script

and you can then call your AWK script like this:

`$ echo "something" | ./awk-script`

Answer 3

Put the part from BEGIN....END{} inside a file and name it like my.awk.

And then execute it like below:

awk -f my.awk life.csv >output.txt

Also I see a field separator as ,. You can add that in the begin block of the .awk file as FS=","
