Ok, so this is not really an OpenBSD question but I am doing this on an OpenBSD system and I am about to lose my mind...
I have done some basic shell scripting before but I've not had to deal with actual integer math before and now it is killing me. The script takes a parameter in (year number) and is supposed to subtract 1900 from it and then multiply the result by 365. (This is part of a larger script that deal with converting dates to a single numeric value, but this one problem is an example of the problems I am having with this entire script.) So, this is what I have: #!/bin/sh month=$1 day=$2 year=$3 dayscount=$(expr ($year - 1900) * 365) echo $dayscount exit This will generate a "syntax error: `$year' unexpected" error. I have tried all sorts of variations and I am not getting it!!! HELP!!! BTW, obviously I need a good book on SH programming. Any suggestions? Thanks, Peter
