I want to download a provisioning script that reads some configuration parameters via
read, and execute it:
curl http://example.com/provisioning.sh | sh
The problem is, that the
read command in the script is call with the
-i parameter to provide a default:
read -p "Name: " -i joe name
If I download the script, set the
+x permission and run it, everything's fine.
If I run it with
cat provisioning.sh | sh or
sh provisioning.sh, it fails with:
read: Illegal option -i
Why wouldn't read support providing a default if it's run via sh?
But whatever, I'll remove the
-i, being left with
read -p "Name: " name
Now if I run the script via
cat provisioning.sh | sh, it won't do anything. Why is that?
