[linux] script cdback cd.to.previous.dir *was* Re: [linux] pracovny adresar po opusteni mc

[Peto - www.lentus.sk]

Ahoj.
OK, nieco podobne potrebujem aj ja v zsh {resp. kvoli univerzalnosti v 
bash/tcsh}.

1. Existuje nejaky prikaz/opsna pre cd --back [nieco ADVANCED v zsh?]
{
cd /4/232/3434/5465
cd
ooops, zase
cd /4/232/3434/5465 [namiesto tohto, radsej cd --back  -> najma, ak si 
nepmatam, kde som vlastne bol]
}

2. vid 1 s tym, ze to pojde aj v bashi a tcsh?
{keby sa niekomu xcelo urobit script, myslim, ze vela ludi by to ocenilo :)}
