For loop in bash (can be used on command line or in script)

There are so many versions of Bash around and it can be frustrating, to me at least, to do some things for not knowing what is available on a given machine. Well here is one, the for loop. Here are a few different ways to do the same thing (and I am sure there are many others) . The first two below work on current linux machines but only the third works on Solaris 5.8′s version of Bash. Enjoy

for ((i=0;i<=5;i+=1));  do echo anda$i; done;
for seq 6 7;  do echo anda$i; done;
for i in 8 9 10 11 12; do cvs tag -d  anda$i; done;
