Thanks in advance for any advice you have to share.

I have been trying to write a script into Hazel to sum the numbers in a text file. I don't have much experience and have tried a lot of different solutions in both bash and Applescript without any results.

Here is an example text file from which I would like to add the numbers preceded by ": $"

**15.44.04** Art materials : $9 Transport : $4.50 **15.44.21** Art materials : $18 Art materials : $25 Food : $11.50 **20.03.53** Miscellaneous : $20 **20.04.02** Food : $10

I woiuld like to append the text "**Total: " with the sum of the values to the end of the file.

Is something like this possible using bash or Applescript?

Thanks again,

Robert

To run the script with Hazel, you can keep the shell as /bin/sh and use $1 to refer to the file being processed:

awk -F\$ '{x+=$NF}END{print "\n**Total: $"x}' "$1" >> "$1"

The script above is only meant to be used with files that don't already have a **Total line at the end. This would replace an existing **Total line:

t=$(sed '/^\*\*Total: /d' "$1") awk -F\$ '{s+=$NF}1;END{print "\n**Total: $"s}' <<< "$t" > "$1"

sed /pattern/d deletes lines. If the text after the sed command ends with two linefeeds, $() removes both of them. awk -F\$ sets the field separator, like BEGIN{FS="$"} . $NF (number of fields) is the value of the last field.
