Using input from read to allow user to designate a specific volume
I am attempting to script the creation of MacOS installation flash media using read to allow the user to designate the name of the volume and store it in the variable VOLNAME. When I run the script, and input the name of the volume, I get the error:
Code:
': not a valid identifier: `VOLNAME
HSInstaller: line 7: VOLNAME: command not found
Code:
#!/bin/sh
# script for creating High Sierra installation media
# Get name of USB drive Volume
echo "Volume name to be used to create installation media (current volume content will be erased)"
read VOLNAME
sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/$(VOLNAME)
I was able to use a similar substitution in a script to connect a network share without issue:
Code:
#!/bin/sh
# script for connecting to file shares.
# Get UserID and password.
echo " UID"
read UID
echo "Password"
read -s password
# Have user provide path
echo "Provide the network path to the directory you wish to connect to."
echo "use the following format:server/directory/directory"
echo "for example AR101/Dir/Team"
read NetPth
open smb://$UID:$password@$NetPth
I've had no issues with the second script. Not sure why the first is unable to use the input given. Any advice would be appreciated.
