#bzip3 continues to amaze me:
-rw-r--r-- 1 ~~~ ~~~ 100M Apr 1 2025 outbox.json
$ simplify $(bzip3 < outbox.json |wc -c)
4.57 MiB
$ simplify $(xz -9e < outbox.json |wc -c)
4.69 MiB
$ simplify $(zstd --ultra -22 < outbox.json |wc -c)
5.06 MiB
(I didn't time it, but it was much faster than the other two)
Also, just in case anyone's curious, simplify (poor name pick, but I couldn't think of anything better) is just a bash function for converting byte counts to an SI unit:
function simplify { #Reduces a big bytes count down to megabytes or whatnot
local steps num
[ $1 ] || ( warn "simplify() called without parameters\n (requires a number of bytes with no unit name)"; return 1 )
steps=0
num=$1
while [[ $(echo "$num > 1024" |bc) == 1 ]] #bc has to be used because num is a float
do
let steps++
num=$(echo "$num/1024" |bc -l)
done
#Cut off after two decimal place:
num=$(echo "$num" |sed 's/\(\.[0-9][0-9]\)[0-9]*$/\1/')
printf "$num "
case $steps in
0) echo b;;
1) echo KiB;;
2) echo MiB;;
3) echo GiB;;
4) echo TiB;;
5) echo PiB;;
6) echo EiB;;
7) echo ZiB;;
8) echo YiB;;
*) echo "1024 ^ $steps bytes";;
esac
