Best practice for bracket comparisons?
So, I have no formal higher education in programming at all and am self taught. I am now wondering what would be considered best practices? Like should I hard code a variable, then compare it to what I want to know or achieve, or should I just put the commands with in the brackets?

Example, a script I am writing now loops through /Users to get all local (synchronized) accounts and checks their group membership of the admin group. If they are a member of the admin group a receipt file gets placed on the machine, and the policy is logged as being ran on that machine. If the results return back nothing the script just exits. Then I can build a policy report of every machine in my enterprise that has local admin accounts and go from there.

I know how to code all of this, but I am not sure what would be considered, "best practice."

Like, should I just construct it like this: if [[ some command with a loop == 1 ]] or if [[ $variable == 1 ]] then hard code my variable in the script?

It works either way I suppose.

Thanks for taking the time to read this.

Tom

NOTES

       YP/NIS, NIS+ and LDAP users should be aware that it's possible to have conflict with users configured in here with the result that an error
       will occur.

       You  should  ensure that local user's home accounts are located on local filesystems - e.g. creating a new entry in /home when it's mounted
       with automount will not work and as such the user may not be created.
