Estou tentando usar o comando dirs com a opção + N. O manual diz:
dirs [-clpv] [+n] [-n]
Without options, displays the list of currently remembered directories. The default display is on a single line with directory names separated by spaces. Direc-
tories are added to the list with the pushd command; the popd command removes entries from the list.
+n Displays the nth entry counting from the left of the list shown by dirs when invoked without options, starting with zero.
dirs -v mostra:
0 /dir1/
1 /dir2/
2 /dir3/
No entanto, dir + n 1, dir + N 1, dir -v + n 1, dir -v + N 1 fornecem:
bash: dirs: +n: invalid number
dirs: usage: dirs [-clpv] [+N] [-N]
Alguém sabe o que estou fazendo de errado?
obrigado
