 I always forget commands that I rarely use. Moreover, it is difficult to search them from shell history. There are many similar commands, but they are all different.
 
 e.g. 
-- `$ awk -F, 'NR <=2 {print $0}; NR >= 5 && NR <= 10 {print $0}' company.csv` (What I am looking for)
-- `$ awk -F, '$0 !~ "DNS|Protocol" {print $0}' packet.csv`
-- `$ awk -F, '{print $0} {if((NR-1) % 5 == 0) {print "----------"}}' test.csv`
+- `awk -F, 'NR <=2 {print $0}; NR >= 5 && NR <= 10 {print $0}' company.csv` (What I am looking for)
+- `awk -F, '$0 !~ "DNS|Protocol" {print $0}' packet.csv`
+- `awk -F, '{print $0} {if((NR-1) % 5 == 0) {print "----------"}}' test.csv`
 
 In the above case, I search by `awk` from shell history, but many commands hit.
