A user frequently runs a two-step process: first, they change to a project directory and set a variable, then they run a build script. They want to encapsulate this into a single command that persists for the current session. Which approach should they use?

Create an alias for the entire sequence

Set the variable and run the build script manually each time

Define a shell function in ~/.bashrc

Write the commands to a script and execute it with `bash script.sh`

A user wants to prevent duplicate commands from being saved in the shell history and also wants the history to be shared across multiple terminal sessions. Which configuration should be added to ~/.bashrc?

export HISTCONTROL=erasedups and export PROMPT_COMMAND='history -c'

export HISTIGNORE='ls' and export PROMPT_COMMAND='history -w'

export HISTSIZE=1000 and export HISTFILESIZE=2000

export HISTCONTROL=ignoredups and export PROMPT_COMMAND='history -a'
