A user has an alias 'ls' that includes '--color=auto'. They run a script that calls 'ls' and notice the output is not colored. The script sources ~/.bashrc. What is the most likely reason?

The script uses 'command ls' which bypasses aliases.

The PATH in the script does not include the alias directory.

The script runs in a subshell that does not inherit aliases.

Aliases are not expanded in non-interactive shells by default.

What is the purpose of the `${VAR}` syntax compared to `$VAR`?

It prevents the variable from being expanded

It allows the variable name to be followed by additional characters without ambiguity

It is the only way to expand a variable

It is used only for environment variables, not shell variables

A user runs 'type -a ls' and gets three outputs: 'ls is aliased to `ls --color=auto'', 'ls is /usr/bin/ls', and 'ls is /bin/ls'. What does this indicate?

The output indicates a conflict that must be resolved.

The alias takes precedence over both external commands.

The external commands take precedence over the alias.

The alias and external commands are all used simultaneously.

A script needs to assign the output of 'date +%Y' to a variable YEAR, then print 'Year: 2025'. The script currently has: YEAR=$(date +%Y); echo "Year: $YEAR". However, the output is 'Year: 2025' with a trailing newline. What is the issue?

The command substitution includes a trailing newline, which is stored in YEAR.

The double quotes around $YEAR cause the newline to be preserved.

The echo command adds a newline by default.

The date command outputs a newline that is not stripped by $().
