Is there a way to use bash “read” command in the %post installation? how to redirect the standard output to a terminal for user interaction?
Sure it’s possible.
%post
iotty=`tty`
exec > $iotty 2> $iotty
read -p "Enter your first name: " firstname
read -p "Enter your last name: " lastname
echo "Your name is: $firstname $lastname"
If the installation has a GUI running, you can use zenity in some form to avoid TTY switching.
Thank you, the installation is graphical. I used the above suggestion but the installation hangs and regarding to the zenity, how to use it during the %post
kickstart?
Something like:
%post
firstname=$(zenity --entry --text=“Enter your first name”)
lastname=$(zenity --entry --text=“Enter your last name”)
zenity --info --text=“Your name is: $firstname $lastname”
Thank you all. The tty also worked - all I had to do was to switch the display (Alt-Ctl-f1)
