Quante volte abbiamo digitato il comando tar per estrarre un archivio, e ci siamo accorti di averlo fatto in una directory sbagliata?<\/p>\n

E se magari la \u201cdirectory sbagliata\u201d fosse una con un centinaio di files? Non serve imprecare, e rimboccarsi le maniche per cancellare i files giusti, ma basta dare un semplice comando in \u201cpipeline\u201d.<\/p>\n

\n

tar tf – | while read filename; do rm -rf \u201c$filename\u201d; done<\/p>\n<\/blockquote>\n

oppure pi\u00f9 rapidamente (se non ci sono spazi nei filename):<\/p>\n

\n

tar tf – | xargs rm -rf<\/p>\n<\/blockquote>\n

Vediamo nel dettaglio cosa stiamo facendo. Nella prima istruzione, il parametro \u201ct\u201d di tar indica di non estrarre realmente l\u2019archivio ma solo di leggerne il contenuto; quest\u2019ultimo verr\u00e0 mandato in \u201cpipe\u201d al comando successivo che rimuover\u00e0 solo i files contenuti nell\u2019archivio in questione.<\/p>\n
