Quick note: How to find queries, SP's or jobs that use a linked server?

Here is the query below that can pull all above results.

Declare @VName varchar(256)
Declare Findlinked cursor
LOCAL STATIC FORWARD_ONLY READ_ONLY
     FOR
Select name
   From sys.servers
   Where is_linked = 1
      
Open Findlinked;
Fetch next from Findlinked into @VName;

while @@FETCH_STATUS = 0
Begin
   SELECT OBJECT_NAME(object_id) 
      FROM sys.sql_modules 
      WHERE Definition LIKE '%'+@VName +'%' 
      AND OBJECTPROPERTY(object_id, 'IsProcedure') = 1 ;
      
   Fetch next from Findlinked into @VName;
End

Close Findlinked
Deallocate Findlinked

SSIS Jobs are different, Here is one for SSIS jobs with Job Name and Details

LOCAL STATIC FORWARD_ONLY READ_ONLY

Select name AS name
   From sys.servers
   Where is_linked = 1
      
Open Findlinked;
Fetch next from Findlinked into @VName;

while @@FETCH_STATUS = 0
Begin
   SELECT OBJECT_NAME(object_id) as ProcedureName 
      FROM sys.sql_modules 
      WHERE Definition LIKE '%'+@VName +'%' 
      AND OBJECTPROPERTY(object_id, 'IsProcedure') = 1 ;
      
   Fetch next from Findlinked into @VName;
END
Close Findlinked

Open Findlinked;
Fetch next from Findlinked into @VName;

while @@FETCH_STATUS = 0
Begin
   SELECT j.name AS JobName,js.command 
      FROM msdb.dbo.sysjobsteps js
         INNER JOIN msdb.dbo.sysjobs j
            ON j.job_id = js.job_id
      WHERE js.command LIKE '%'+@VName +'%'
   Fetch next from Findlinked into @VName;
