shell

hi all,

i have made a shell script but i need to know if i need a wait command in-between my commands, because the first command takes ages to copy over something (about 5 minutes) and the next command is the next line, so will it not complete the copy off?

many thanks

rob

Shell commands are, unless they get executed in the background or otherwise handed off (say 'at' service), executed sequentially.

so should i put in a wait command in-between, whats the command syntax?

no, you should not do that. The normal flow means every command will wait for the previous to complete. So you do not need to do anything. But probably you started some background processes, which will run independently and therefore you need to check if that one already completed or not. Without knowing your script we assume you have no backround jobs and therefore all the commands will be executed strictly one by one, one after another...

vim-cmd vmsvc/power.shutdown VMID
mkdir /vmfs/volumes/datastore1/clone
vmkfstools -i /vmfs/volumes/datastore1/source/server.vmdk /vmfs/volumes/datastore1/dest/clone/server.vmdk
**the above line the copy is quite a long time as its copying a virtual hard drive**
cp /vmfs/volumes/datastore1/source/server.vmx /vmfs/volumes/datastore1/dest/clone
vim-cmd solo/registervm /vmfs/volumes/datastore1/dest/clone/server.vmx
vim-cmd vmsvc/power.on VMID

i believe wait is not necessary; please post the output of your modified script below:
