List directories recursively showing its sizes using only ls and grep

ls -lhR | grep -e "total\|:$"
ls -lhR Lists everithing using -l "long listing format" wich includes the space used by the folder. Displays it in -h "human readable form" (i.e. 2.2G, 32K), and -R recurses subfolders. grep -e using a regex, show lines containing the word "total" or a ":" at the end of the line (those with the name of the folder) only.
Sample Output
.:
total 60K
./documents:
total 2.2G
./error:
total 32K

  • This will check if there are any empty directories, or newly emptied directories, in a list of directories. It will then delete all of those directories. It works with gnu find and OSX/BSD find.

  • Here's an annotated version of the command, using full-names instead of aliases. It is exactly equivalent to the short-hand version. # Recursively list all the files in the current directory. Get-ChildItem -Recurse | # Filter out the sub-directories themselves. Where-Object { return -not $_.PsIsContainer; } | # Group the resulting files by their extensions. Group-Object Extension | # Pluck the Name and Count properties of each group and define # a custom expression that calculates the average of the sizes # of the files in that group. # The back-tick is a line-continuation character. Select-Object ` Name, Count, @{ Name = 'Average'; Expression = { # Average the Length (sizes) of the files in the current group. return ($_.Group | Measure-Object -Average Length).Average; } } | # Format the results in a tabular view, automatically adjusted to # widths of the values in the columns. Format-Table -AutoSize ` @{ # Rename the Name property to something more sensible. Name = 'Extension'; Expression = { return $_.Name; } }, Count, @{ # Format the Average property to display KB instead of bytes # and use a formatting string to show it rounded to two decimals. Name = 'Average Size (KB)'; # The "1KB" is a built-in constant which is equal to 1024. Expression = { return $_.Average / 1KB }; FormatString = '{0:N2}' } Show Sample Output

What Others Think

What is wrong with du -h ?
michelsberg · 282 weeks and 4 days ago
I don't have permission to run du (or to install it) on the server.
Sebasg · 282 weeks and 4 days ago
Ok, I thought du would exist on any relevant *nix since it is in the coreutils.
michelsberg · 282 weeks and 4 days ago
very good
aelam · 282 weeks and 4 days ago
you're right, i understand it's use. for those have root on machine: du -csh /var/* [me@this] 22 19:39 Tue Jan 22 > sudo du -shc /var/* 2.0M /var/backups 548M /var/cache 700K /var/crash 4.0K /var/games 195M /var/lib 4.0K /var/local 0 /var/lock 6.7M /var/log 4.0K /var/mail 4.0K /var/metrics 4.0K /var/opt 0 /var/run 88K /var/spool 11M /var/tmp 763M total

To memorize it better, german speakers can use ls -Roh | grep "insgesamt\|:$" ("Roh" means raw) ls -o is almost identical to ls -l, but does only list owner info (and no group name).
