I  try to extract all files in  all sub directories   by  this command   $ find -name *.bz2 -print  -exec bizp2 -d *.bz2 {}\;find: missing argument to `-exec'but it doesnot work :(btw I do not understand  the usage of {};
how to unzip all files in sub directories
exec
There are two errors in your command:leave out the *bz2 option to bzip2, the {} will be replaced by any file find returnsadd a space between {} and \;so the full command would be find -name *bz2 -print -exec bzip2 -d {} \;
