To add multiple columns in csv file
Hi Guys,

Can you help to add static values at the end of the csv file with headers

Code:
input_file
id,name
1,neo
2,pull

Expected
id,name,status,entry,g_id
1,neo,done,2019-11-01T07:14:23,pass
2,pull,done,2019-11-01T07:14:23,pass

My try but not able replacing properly and unable to achieve for adding another columns

Code:
awk '{printf "%s", $0 "\done\n"}' input_file
