使用 xargs 解压多个文件

Question

I'm trying to unrar a tonne of files in a directory using xargs...

having little luck with this command:

find /home/jchristian/bfdata/2014/*.rar -print0 | xargs -0r unrar x

gives the following output:

UNRAR 5.00 beta 3 freeware      Copyright (c) 1993-2013 Alexander Roshal
Extracting from /home/jchristian/bfdata/2014/bfinf_horse_140106to140112_140115120001.rar

No files to extract

Yes, When I run unrar with that file outputted above - It extracts gracefully...

unrar x     /home/jchristian/bfdata/2014/bfinf_horse_140106to140112_140115120001.rar

Extracting  bfinf_horse_140106to140112_140115120001.csv               OK 
All OK

Any ideas?

Answer 1

this should work

find /home/jchristian/bfdata/2014/ -name *.rar | xargs -n 1 unrar x

find need a path and an expression, so

find /home/jchristian/bfdata/2014/*.rar -print0

will return nothing

Answer 2

You could skip the xargs step by using find -exec

find /home/jchristian/bfdata/2014 -name \*.rar -exec unrar x {} \;

You need e or x after unrar
