be able to "tail" last N lines of a file

[danielb2]

so I can use ranges to print the lines, but how would I for example print the last 10 lines of a file?

I can do this:

bat file.txt-r $(echo $(wc file.txt | awk '{print $1}') - 10 | bc):

but is there no better way?

I agree, it would be cool if we could do Python-style negative-number ranges like this:

bat file.txt -r -10:

which would mean: "10 lines from the end until the end". It would be great if you could open a feature request for this.

Until then, your solution seems fine. Another option would be to use tail on the input. This might require you to explicitly set the language:

tail -n10 file.txt | bat -l<language>

Or you could use tail on the output, but you would need to get rid of the borders (e.g. with -p/--plain) to make sure that the last line of bats output isn't counted. And you need to force colorization, e.g. with -f:

bat -fp file.txt | tail -n10

SO there's no way for bat to know what the last 10 lines of a file are?
