Got below error:
Makefile:2: *** missing separator. Stop.
Check the Makefile using cat -e -t -v:
zzh@ZZHPC:/zdata/Github/zimplebank$ cat -e -t -v Makefile createdb:$ docker exec -it postgres16 createdb --username=root --owner=root zimple_bank$ $ dropdb:$ docker exec -it postgres16 dropdb zimple_bank$ $ .PHONY createdb dropdb
make defines a tab is required to start each recipe. All actions of every rule are identified by tabs. If you prefer to prefix your recipes with a character other than tab, you can set the .RECIPEPREFIX variable to an alternate character.
Replaced the identation spaces to tabs:
