You want to print information about ChromeOS devices at your school from Org Units based on graduation year.

Example 1 CSV File OrgUnit.csv, exactly the data you want, keypattern and keyvalue are not required.

OrgUnit
/Students/2020
/Students/2021
...

For each row, the value from the OrgUnit column is used as the Org Unit name.

gam csvkmd cros_ous OrgUnit.csv keyfield OrgUnit print cros

Example 2 CSV File GradYear.csv, you have to convert GradYear to Org Unit name /Students/GradYear, keyvalue is required.

GradYear
2020
2021
...

For each row, the value from the GradYear column replaces the keyField name in the keyvalue argument and that value is used as the Org Unit name.

gam csvkmd cros_ous GradYear.csv keyfield GradYear keyvalue "/Students/GradYear" print cros

Example 3 CSV File GradYear.csv, you have to convert GradYear to Org Unit name /Students/LastTwoDigitsOfGradYear, keypattern and keyvalue are required.

GradYear
2020
2021
...

For each row, the value from the GradYear column is matched against the keypattern and the matched segments are substituted into the keyvalue argument and that value is used as the Org Unit name.

gam csvkmd cros_ous GradYear.csv keyfield GradYear keypattern '20(..)' keyvalue '/Students/\1' print cros

Example 1 Print information about all ChromeOS devices with a serial number that starts with HY3 or 5CD.

gam crosqueries "id:HY3,id:5CD" print cros allfields nolists

Example 2 Print information about all ChromeOS devices in two Org Units that contain spaces in their names.

gam crosqueries "\"orgUnitPath='/Students/Middle School/2021'\",\"orgUnitPath='/Students/Middle School/2020'\"" print cros allfields nolists

This is equivaluent to:

gam cros_ous "'/Students/Middle School/2021','/Students/Middle School/2020'" print cros allfields nolists
