I want write my own alias called oepnserver. The functions of the oepnserver are:
- show my ip address
- use python module to start a server on current folder.
The detailed code is listed below:
alias openserver="ifconfig wlan0 |grep inet |awk '{print $2}' && python3 -m http.server 54188"
When I type oepnserver, my terminal only shows:
inet 172.34.162.200 netmask 255.255.224.0 broadcast 172.34.191.255 Serving HTTP on 0.0.0.0 port 54188 (http://0.0.0.0:54188/) ...
However, my expectation was
172.34.162.200 Serving HTTP on 0.0.0.0 port 54188 (http://0.0.0.0:54188/) ...
I also try to use the ifconfig wlan0 |grep inet |awk '{print $2}' along, and I get the correct output.
Should I use another way to combine these two commands instead of &&? Or I just made some typo?

Based on your shown code I am trying to optimize it which could be done by single awk.
ifconfig wlan0 | awk '/inet /{print $2}' && your python code
Also IMHO you should try to make this as a function rather than alias.
