[gelöst] Mint 18.1: Symbolik Link löschen

[Lazman]

Moin,

ich habe einer Anleitung folgend folgenden Symbolischen Link erstellt:

sudo ln -s /usr/local/lib/fpc/3.0.0/ppcross386 /usr/bin/

Wie lösche ich diesen Link wieder?

Gruß Heiko

sudo rm /usr/bin/ppcross386 (and a subsequent "hash -r" if you find bash still expects to find ppcross386 in /usr/bin after that)

Hello,

thank you.

sudo rm /usr/bin/ppcross386

i understand this, but
i don't understand this.

(and a subsequent "hash -r" if you find bash still expects to find ppcross386 in /usr/bin after that)

Greeting
Heiko

You would have understood if you had run into the problem it solves so the quickest reply I could provide is "never mind then". But to wit: bash doesn't scan your entire $PATH each time you invoke an executable, rather, re-invoke one it already knows about. First time you run "pccross386" from the command line bash finds it in /usr/bin and remembers this fact for a subsequent invocation. Even if you then in fact delete /usr/bin/pccross386 as per above, said subsequent invocation would merely tell you bash: /usr/bin/pccross386: No such file or directory also if you by that time had already recreated the link in another directory on your $PATH, such as /usr/local/bin. That is, you'd find it impossible to invoke /usr/local/bin/pccross386 simply as "pccross386" until you told bash through hash -r to forget its cache of stored locations; to forget the now outdated fact that pccross386 lives in /usr/bin.

As said: if you had run into the issue you'd have noticed it...
