Forward function declarations in a Bash or a Shell script?
Great question. I use a pattern like this for most of my scripts:
#!/bin/bashmain() { foo bar baz}foo() {}bar() {}baz() {}main "$@"You can read the code from top to bottom, but it doesn't actually start executing until the last line. By passing "$@" to main() you can access the command-line arguments $1, $2, et al just as you normally would.
When my bash scripts grow too much, I use an include mechanism:
File allMyFunctions:
foo() {}bar() {}baz() {}File main:
#!/bin/bash. allMyfunctionsfoobarbaz
