Whenever sorting, always ask if you are doing numerical or alphabetical sorting.
e.g. I wanted to find the biggest files in the project_s repo. So I ran
$ du project_s 192./.composer/cache/files/phpspec 16 ./.composer/cache/files/fideloper/proxy 1632 ./.composer/cache/files/maximebf 84496 ./.composer/cache/files 854328 ./.composer/cache/repo/https---repo.packagist.org 854328 ./.composer/cache/repo 938832 ./.composer/cache 938840 ./.composer 2810896 .
Next I sorted by piping into sort and sorting on first key
$ du project_s | sort -k 1 968 ./node_modules/jsdom/node_modules/acorn/dist 9696 ./node_modules/terser 971280 ./node_modules 976 ./node_modules/handlebars/dist/amd/handlebars/compiler 984 ./node_modules/array-includes/node_modules/es-abstract/2019 9912 ./node_modules/lodash 992 ./vendor/phpunit/phpunit/tests/end-to-end/regression
As you can see, the order was not what I expected because
text not numbers. Therefore I had to tell sort to sort numerically with
sort -k 1 -n
$ du project_s | sort -k 1 -n 968 ./node_modules/jsdom/node_modules/acorn/dist 976 ./node_modules/handlebars/dist/amd/handlebars/compiler 984 ./node_modules/array-includes/node_modules/es-abstract/2019 992 ./vendor/phpunit/phpunit/tests/end-to-end/regression 9696 ./node_modules/terser 9912 ./node_modules/lodash 971280 ./node_modules
Note that this applies within vim too - e.g.
! sort -n
