exemple test=132

[Thomas-Chqt]

Should do :

bash-3.2$ test=123
bash-3.2$ echo $? "'$test'"
0 '123'

bash-3.2$ te.st=123
bash: te.st=123: command not found
bash-3.2$ echo $? "'$test'"
127 ''

bash-3.2$ test=123
bash-3.2$ echo $test
123
bash-3.2$ test=
bash-3.2$ echo $? "'$test'"
0 ''

bash-3.2$ te st=123
bash: te: command not found
bash-3.2$ echo $? "'$test' '$te' '$st'"
127 '' '' ''

bash-3.2$ test=123 ls -l
total 5560

@jizots in the case of a environment set before a regular command without pipe like test=123 ls -l i can do it after the lexer by just removing one token but i case of using with a pipe like test=123 | ls -l or pwd | test=123 you need to do it inside the execution by just checking if its a good identifier, if it is, just ignore it, if not, use it as a command (it will print command not found)

OK. I will modify code.
