A developer needs to temporarily change the default text editor used by git to nano for the current session only, without affecting other terminals or future sessions. Which command should the developer run?

export EDITOR='nano' > ~/.bashrc

A system administrator notices that a custom script located in /usr/local/bin is not found when run by a non-login shell (e.g., a script invoked from cron). The admin confirms /usr/local/bin is in the PATH for interactive shells. What is the most likely reason and the correct fix?

The script is not executable; run chmod +x /usr/local/bin/script.

The script is owned by another user; change ownership to root.

The PATH is set in ~/.bashrc, which is not sourced by non-interactive shells; add the export to /etc/profile or use the full path in the cron job.

The script has a syntax error; fix the script and re-run.

An admin runs a script that produces verbose output. The admin wants to save the output to a log file while still seeing it on the screen, and also wants to capture any error messages. Which command accomplishes this?

./script.sh 2>&1 | tee logfile.txt

./script.sh 2> logfile.txt | tee logfile.txt
