This project is a custom Linux bash terminal program, implemented in C++, which supports the sequential and parallel execution of programs together with a pipeline.

• Pipeline: Execute commands in a pipeline using the | delimiter.
• Sequential Execution: Execute commands one after another using the ; delimiter.
• Parallel Execution: Execute commands simultaneously using the , delimiter.
• Subshell Execution: Group commands into a child shell using parentheses, supporting either sequential or parallel execution.

Commands can be connected using the | delimiter, where the output of one command serves as the input to the next.

ps aux | grep python | wc -l

This will count the number of Python processes running.

Commands can be executed sequentially by separating them with a semicolon ;.

echo "Hello"; sleep 5; echo "World"

This will print "Hello", wait for 5 seconds, and then print "World".

Commands can be executed in parallel by separating them with a comma ,.

echo "Hello", sleep 5, echo "World"

All three commands will execute simultaneously.

Commands can be grouped into a subshell using parentheses (). The subshell can then be executed sequentially, in parallel, or as a pipeline.

(echo "Hello"; sleep 3; echo "World")

(echo "Hello", sleep 2, echo "World")

(echo "Hello" | sleep 2 | echo "World")

Sequential, parallel, and pipeline executions can be combined for more complex command execution flows.

echo "Hello" | cat ; cat config.txt; cat manifest.txt | grep "Ship" | tr /a-z/ /A-Z/

This will print "Hello", display the contents of config.txt, and then process manifest.txt to search for "Ship" and convert the results to uppercase.

echo "Hello" | cat , cat config.txt , cat manifest.txt | grep "Ship" | tr /a-z/ /A-Z/

This will execute the commands in parallel with pipelines incorporated.
