I want to write a shell script to execute some commands in sequence (the next one starts only after the previous has finished and so on). I've never written a bash script before and I couldn't find the appropriate sequence.
I know that in the terminal you do things like yarn this && yarn that && yarn other
and it works but I don't know the equivalent inside a shell script.
#!/bin/sh
direnv allow
# now wait for direnv allow to finish
direnv reload
# now wait for direnv reload to finish
yarn start:server
The shell will execute each command one after another serially as written. Servers often daemonize, ie fork() and have the parent return. They usually have -f
flag to suppress that behavior, precisely because you may want that serial behavior.
