To get the space by directory, you can use the du command. It summarize disk usage of each FILE, recursively for directories.

With a redirection, you can export the result and find the directories that used the most space.

du mydirectory > du.csv

the space for one directory

For one directory:

du -hs

where the options mean:

  • s: summary
  • h: human readable

the top disk usage by directory

The following command gives the top 10 subdirectory from the current directory by disk usage.

du | grep logs | sort -n | cut -f 2- | while read a; do du -sh "$a"; done | tail
3.3M    ./instances/instance1/diagnostics/logs/OracleBIJavaHostComponent
6.3M    ./instances/instance1/diagnostics/logs/OPMN/opmn
6.3M    ./instances/instance1/diagnostics/logs/OPMN
14M     ./instances/instance1/diagnostics/logs/OracleBIPresentationServicesComponent/coreapplication_obips1
14M     ./instances/instance1/diagnostics/logs/OracleBIPresentationServicesComponent
25M     ./instances/instance1/diagnostics/logs
40M     ./Oracle_BI1/cfgtoollogs/oui
40M     ./oracle_common/cfgtoollogs/oui
40M     ./oracle_common/cfgtoollogs
40M     ./Oracle_BI1/cfgtoollogs


  • du list the subdirectory with the disk usage
  • grep filters the result for only the logs subdirectory
  • sort sort the result
  • tail shows only the 10 last lines

For OBI:


Loop through children

  • files
for filename in /$baseDir/dirPath/*.txt; do
    echo $filename
  • directory
for childPath in /my/directory/path/*; do
    if [ -d "$childPath" ]; then

Check if a path is a directory

if [ -d /my/path ]; then
  echo 'This is a directory'
  echo 'This is not a directory'
