Part 1.2 : Syntax errors

Syntax errors of tokens (check in lexer)

NO ERRORS

• starting with redirection : no error > file.txt, < file.txt, << file.txt, >> file.txt : in bash, no error
• starting with pipe generates error : | echo coucou
• | >, | <, | >>, | << : no error

1st stack of errors

• redirection followed by pipe => error
• < |, > |, >> |, << | : error
• 2 pipes qui s'enchainent : error | | msg : bash: syntax error near unexpected token |'`

2nd stack of errors

• redirection without any string afterwards => error
• echo < , echo >, echo >> , echo << : error
• echo | : same error for pipe msg : bash: syntax error near unexpected token newline'`

3rd stack of errors

• redirection following another redirection => error
• msg : depends on the 2nd redirection token
• echo < >>, echo > >>, echo >> >>, echo << >> : all have same error msg : bash: syntax error near unexpected token `>>'
