rshell

rshell is a program I wrote that functions alomost the same sa BASH terminal. it can run commands, and use seperators such as ; , || ,and &&. it also take in comments, which is indicated after the sign #. everything after # in a command line is a comment, and will not execute with the commands.

each command can take in arguments using space to seperate each term.

inputing true in the command line means "command" executed. inputing false in the command line means "command" did not executed.

to exit the program, simply type exit as a command.

##EDGE CASES: 1. seperator comes in pair: having &&& will consider having a seperator && and a command &, which will return false. the same apply for |||. 2. however, having ;;; will means nothing, and the program does nothing. 3. having single command with connector, for example && ls;, the command ls will be executed, so as in the case of ls &&;. the same apply to seperator ||. 4. however, having a space before or after the connector will result in false, such as && ls; or ls && ;.

#Bugs

2. spaces and tab by itself wont be ignored. and be run as error command.
3. comment by is self will report as error command.
