I'm writing a script which is becoming a little on the lengthy side for easy management (>100 lines). Instead of having half-a dozen nested IFs, I've chosen to use a sequence of single-level IFs and a few control variables that are set during the IFs.

However, I don't want to have to trawl through all these IFs to be able to edit the main body of the program. I can use a function, but this still has to be defined before it's used.

Is there any way I can push this stuff down to the bottom of the script somewhere and leave me with all the nice stuff at the top to edit?

Thanks,
Steve

No, but you can put the fns in another sh file and include it at the top of your main script in one line via

. fns.sh
or
source fns.sh

Note that the first version (ie dot space filename) also works in ksh and prob other shells as well.
