How to count number of file in a bucket-folder with gsutil

The gsutil ls command with options -l (long listing) and -R (recursive listing) will list the entire bucket recursively and then produce a total count of all objects, both files and directories, at the end:

$ gsutil ls -lR gs://pub

TOTAL: 144 objects, 102723169 bytes (97.96 MB)

If you really just want the total, you can pipe the output to the tail command:

$ gsutil ls -lR gs://pub | tail -n 1
TOTAL: 144 objects, 102723169 bytes (97.96 MB)

UPDATE

gsutil now has a du command. This makes it even easier to get a count:

$ gsutil du gs://pub | wc -l
232

You want to gsutil ls -count -recursive in gs://bucket/folder? Alright; gsutil ls gs://bucket/folder/** will list just full urls of the paths to files under gs://bucket/folder without the footer or the lines ending in a colon. Piping that to wc -l will give you the line-count of the result.

gsutil ls gs://bucket/folder/** | wc -l

If you have the option to not use gsutil, the easiest way is to check it on Google Cloud Platform. Go to Monitoring > Metrics explorer :

• Resource type : GCS Bucket
• Metric : Object count Then, in the table below, you have for each bucket the number of document it contains.
