What about if there are more lines with the same name like MIN_PASSWORD_LENGTH?

In that case, all that changes is the field separator in awk. So, this:

Code:

... awk '{ if ...

becomes:

Code:

... awk -F= '{ if ...

Now, I assumed (perhaps incorrectly) that any additional lines called "MIN_PASSWORD_LENGTH" would be commented out. For example:

Code:

MIN_PASSWORD_LENGTH=7
#MIN_PASSWORD_LENGTH=2
#MIN_PASSWORD_LENGTH=3
#MIN_PASSWORD_LENGTH=6

The grep that I used accounts for that. The ^ character in the grep tells it to return those lines that start with MIN_PASSWORD_LENGTH. So, the first line of the 4 above would be returned; the other 3 would be entirely ignored. Does that do what you need, or would there be more than 1 uncommented line starting with MIN_PASSWORD_LENGTH? Post to let us know if that's the case-- I'm sure we can put something together that works.
