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

Once you start using "Ctrl-R" you will probably never want to use "history | grep ..." and "!..." again.
