KO : | ne fonctionne pas lorsquil est suivi d'un '|' ex: export BANANE=1 | cat -e --> la variable n'est pas crée
OK : >
OK : >>
OK : < fonctionne lorsqu'il est suivi d'un '<' ex: export B00=3 < file --> creer la variable BOO=3
- echo avec variables. ex BOO=2 si la variable n'existe pas, n'effiche rien
echo BOO -> BOO
echo "BOO" -> BOO
echo $BOO -> 2
echo $"BOO" -> BOO
echo "$BOO" -> 2
- pwd prend des arguments mais ne les traite jamais. Les redirections et l'appending fonctionnent, sauf '<'. En effet, pwd ne prend pas d'argument.
