Hadoop: ls: print files size in human readable form

‘-h’ option is used to print the files size in human readable form.

 

Example

hadoop fs -ls -h /user/cloudera/demo1

$hadoop fs -ls -h /user/cloudera/demo1
Found 6 items
-rw-r--r--   1 cloudera cloudera          2 2022-03-22 23:58 /user/cloudera/demo1/a.txt
-rw-r--r--   1 cloudera cloudera      4.5 M 2022-03-22 23:57 /user/cloudera/demo1/apacheNifi.docx
-rw-r--r--   1 cloudera cloudera      5.9 M 2022-03-22 23:57 /user/cloudera/demo1/atlas.docx
-rw-r--r--   1 cloudera cloudera      8.7 M 2022-03-22 23:57 /user/cloudera/demo1/atlasClient.docx
-rw-r--r--   1 cloudera cloudera      6.7 M 2022-03-22 23:58 /user/cloudera/demo1/gradle.docx
-rw-r--r--   1 cloudera cloudera      8.6 M 2022-03-22 23:58 /user/cloudera/demo1/maven.docx

 

You can add -S option to sort the files by their size in descending order.

$hadoop fs -ls -S -h /user/cloudera/demo1

-rw-r--r--   1 cloudera cloudera          2 2022-03-22 23:58 /user/cloudera/demo1/a.txt

  You can add -r option along with -S to sort the files by their size in ascending order.

 

$hadoop fs -ls -S -r -h /user/cloudera/demo1

-rw-r--r--   1 cloudera cloudera          2 2022-03-22 23:58 /user/cloudera/demo1/a.txt
