fesh running drudg fails if output already exists

[varenius]

Tried running fesh with "-f" to overwrite skd, snp and prc files. Got this:

oper@fold:~$ fesh -s On -d r11013
/usr2/sched/r11013.skd exists, delete or use '-f' to get fresh schedule
oper@fold:~$ fesh -s On -d -f r11013

After manually removing snp and prc I tried again, and then it worked.

I'm sorry for the trouble. I believe the issue is that you gave your station code as On instead of on. That conflicts with drudg mapping to lower case. The -h output mentions that STATION and -s should be lower case, but that is still a bit of a rough edge for an unsuspecting user.

We could either map the station code to lower case or refuse one with upper case. I am inclined to the former since that is what drudg does anyway and the latter seems a bit unfriendly (why give an error for something the program could have fixed).
