man comando

ed hai l'help

si poi posso cercare so google...

Ma visto che non ho trovato niente qualcuno ha volgia di aiutarmi?

ls -lR /lib | grep -e '^-' | sort -k 5 -n | tail -n 1 | cut -d' ' -f8


Così lo trovo, ma non uso du.
c'è un modo in du per ottenere solo i fiel e non le directory?

[patel]

una cosa del genere ti va bene ?
du -h / | grep '[[:digit:]]G\b'

DU(P)                      POSIX Programmer?s Manual                     DU(P)

NAME
       du - estimate file space usage

SYNOPSIS
       du [-a | -s][-kx][-H | -L][file ...]

DESCRIPTION
       By  default,  the  du  utility shall write to standard output the size of the file space allocated to, and the size of the file space
       allocated to each subdirectory of, the file hierarchy rooted in each of the specified files. By default,  when  a  symbolic  link  is
       encountered  on  the command line or in the file hierarchy, du shall count the size of the symbolic link (rather than the file refer-
       enced by the link), and shall not follow the link to another portion of the file hierarchy. The size of the file space allocated to a
       file  of  type directory shall be defined as the sum total of space allocated to all files in the file hierarchy rooted in the direc-
       tory plus the space allocated to the directory itself.

       When du cannot stat() files or stat() or read directories, it shall report an error condition and the final exit status is  affected.
       Files  with  multiple  links  shall  be counted and written for only one entry. The directory entry that is selected in the report is
       unspecified. By default, file sizes shall be written in 512-byte units, rounded up to the next 512-byte unit.

OPTIONS
       The du utility shall conform to the Base Definitions volume of IEEE Std 1003.1-2001, Section 12.2, Utility Syntax Guidelines.

       The following options shall be supported:

       -a     In addition to the default output, report the size of each file not of type directory in the  file  hierarchy  rooted  in  the
              specified file. Regardless of the presence of the -a option, non-directories given as file operands shall always be listed.

       -H     If  a  symbolic link is specified on the command line, du shall count the size of the file or file hierarchy referenced by the
              link.

       -k     Write the files sizes in units of 1024 bytes, rather than the default 512-byte units.

       -L     If a symbolic link is specified on the command line or encountered during the traversal of a file hierarchy,  du  shall  count
              the size of the file or file hierarchy referenced by the link.

       -s     Instead of the default output, report only the total sum for each of the specified files.

       -x     When evaluating file sizes, evaluate only those files that have the same device as the file specified by the file operand.

       Specifying  more  than  one  of  the mutually-exclusive options -H and -L shall not be considered an error. The last option specified
       shall determine the behavior of the utility.
