Is there a way to switch user identity within a script (executed as root as part of an installation process) to execute some commands without calling an external script, then return to root to run other commands?
Sort of:
#!/bin/bash
some commands as root
SWITCH_USER_TO user
some commands as user including environment variables checks, without calling an external script
SWITCH_USER_BACK
some other stuff as root, maybe another user id change...1 Answer
No. But you can use sudo to run a shell and use a heredoc to feed it commands.
#!/bin/bash
whoami
sudo -u someuser bash << EOF
echo "In"
whoami
EOF
echo "Out"
whoami
