Useful find examples

Find file, exclude directory

Inside the directory packages, find tsconfig.json files except if they are inside node_modules directory. Excludes node_modules in any level:

$ find ./packages -name tsconfig.json -not -path '*/node_modules/*'
./packages/tsconfig.json

Find files and store in array

Find files whose extension is .md and store them in a bash array:

$ mapfile -d $'\0' mds < <(find . -iname '*.md' -print0)

We make use of the mapfile shell builtin with the shell-quoting $'' syntax to specify NUL byte as delimiter (produced by -print0), redirection and process substitution <(…).
