I built a little Bash script to let you do this: https://til.simonwillison.net/bash/go-script

cat file.txt | ./goscript.sh -c 'script.Stdin().Column(1).Freq().First(10).Stdout()'

It supports this too:

cat file.txt | ./goscript.sh top10.goscript

And this, saved as top10.goscript and made executable:

#!/tmp/goscript.sh
script.Stdin().Column(1).Freq().First(10).Stdout()

Then run like this:

cat file.txt | ./top10.goscript 

It's a fun little hack in Bash, but maybe something like this could be useful as an actual Go program distributed as part of this project.
