Вот решение для сравнения 2 файлов:

#read file1 to df1
#your header seems no good with blank, so i rename it
df1 = pd.read_csv('file1',  sep=',' header=1, names=['PID','STARTED','%CPU','%MEM','COMMAND']])
#df1 is your first file, df2 the second
df_compare = df1.merge(df2.drop_duplicates(), on=['PID','STARTED','%CPU','%MEM','COMMAND'],
                   how='right', indicator=True)

print(df_compare)

#in result, you'll have a column '_merge' with both or right_only
#right_only means only in df2 and not in df1
#after you just filtered:

filter = df_compare._merge == 'both'
df_compare = df_compare[filter].drop(['_merge'],axis=1)

#in df_compare, you have the repeateted rows from df2 and df1, you could reindex if you want
print(df_compare)  

или другое решение (лучше, я думаю):

df_compare = df1[df1.index.isin(df1.merge(df2, how='inner', on=['PID','STARTED','%CPU','%MEM','COMMAND']).index)]
print(df_compare)
