I have gotten the following to work:
for i in {2..10} do echo \"output: $i\" done
It produces a bunch of lines of output: 2
output: 2
Well, as I didn't have the seq command installed on my system (Mac OS X v10.6.1 (Snow Leopard)), I ended up using a while loop instead:
seq
while
max=5 i=1 while [ $max -gt $i ] do (stuff) done
*Shrugs* Whatever works.
