I am trying to extract many rar files at once, but with no successful. I am trying in the order:

>ls *.rar|xargs unrar x
>ls *.rar|xargs unrar e
>unrar e -r *.rar
>for f in *.rar;do unrar e “$f”;done

no ones works. Rar answers every times saying that there are not file to exctract.

>Extracting from damned_file.rar

 No files to extract

If I try to extract the file one by one, then all works fine

>unrar e damned_file.rar
 extracting damned_file.rar                        
 extracting dmaned_file.txt                            OK
 All OK
>

My version of rar is

UNRAR 4.10 freeware      Copyright (c) 1993-2012 Alexander Roshal

What I am doing wrong?

PS: The command

find . -name "*.rar" -exec unrar e {} \;

works fine, but the question remain the same. Why the previous commands fails?

Here is my go-to for loop:

for file in *.rar; do unrar e "$file"; done

xargs puts arguments behind the command provided to it up until the maximum command length for your current shell, so the command would be:

xargs unrar e damned_file.rar another_damned_file.rar yadf.rar

However, unrar only takes a single rar file as argument. The find command you specified runs unrar for every single file it finds, so the command is unrar e damned_file.rar, unrar e another_damned_file.rar.
