Deleting Bulk Photos

[Rob]

I'm trying to mass delete Google User photos that they have set themselves. Instead of doing it individually, I'm trying to do it with GAM.

gam org "x/high school/users/students/2017" delete photo 

and 

gam group x...@domain.com delete photo

Both return the following error:

Getting all users in the G Suite organization (may take some time on a large domain)...

Got 184 users...

184 users are directly in the OU.

Deleting photo for x...@domain.com (1/184)

ERROR: 404: Resource Not Found: photo - notFound

Am I missing something obvious here? It appears because the first user it detects (x) for this example does not have a photo, so it errors out. Is there a way to force it to continue?

Rob,

You've hit one of Gam's weak spots, error handling. There is a fairly straightforward solution by using CSV files. When Gam processes a CSV file, each row is handled independently so errors in one row don't affect processing other rows.

You need to make a CSV file that contains the list of users, then you user gam to process the CSV file.

1: echo "primaryEmail" > user.csv

2: gam org "x/high school/users/students/2017"  print >> user.csv

3: gam csv user.csv gam user "~primaryEmail" delete photo

1: Create a CSV file user.csv with a single row "primaryEmail", this is the header row

2: Use the gam print command to produce the list of desired users and append to user.csv

3: Process the CSV file, each row is run in a separate process, so errors in one row don't affect other rows

As there are multiple processes running in parallel, the processing is quick.

In my advanced Gam a significant fraction of the code is handling exactly this situation. See: https://github.com/taers232c/GAMADV-X

1: gam org "x/high school/users/students/2017" delete photo 

Process each user serially, handle errors, don't stop. This solution will run slower than the CSV file solution as the file is handled serially, for small numbers of user this is probably fine.

If you want parallel processing for greater speed you can do this:

1: gam org "x/high school/users/students/2017"  print users primaryEmail > user.csv

2: gam csv user.csv gam user "~primaryEmail" delete photo

1: Create the CSV file in a single step.

2: Process the CSV file, each row is run in a separate process

If you want grate speed an a log of what happened you can do this:

1: gam org "x/high school/users/students/2017"  print users primaryEmail > user.csv

2: gam redirect stdout ./DeletePhotos.log multiprocess redirect stderr stdout csv user.csv gam user "~primaryEmail" delete photo

1: Create the CSV file in a single step.

2: Process the CSV file, each row is run in a separate process. Intelligently combine the stdout/stderr output from all of the processes into a single log file.
