reuse the history
 

Hi all


I want to reuse command in the shell historys
Which command I can only select "traceroute 192.168.0.5" to run?

$ history |grep traceroute
26 traceroute 192.168.0.5
27 traceroute -n 192.168.0.5
28 traceroute 192.168.0.10
29 traceroute yahoo.com
46 traceroute 192.168.0.33


eg:

history |grep traceroute | awk '{ print$2 " " print$3}' | grep 26

Thank you

I would type "Ctrl-R" (interactive search history starting with more
recent events), then type "trace", then type "Ctrl-R" again until I
find the command I'm looking for, in your case, 4 times. Once you
start using "Ctrl-R" you will probably never want to use "history |
grep ..." and "!..." again.

HTH,
