After 4 years of running a pretty stable linux on my notebook I realized that the time had come that too much software and dependencies have been on my system so I set up a clean system. By doing so I also switched to a tiling window manager called awesome (with which I am pretty happy so far). One problem (not really since it is the purpose of going to awesome) though is that everything has to be done from the command line. in particular when I join a network I have to use the network manager command line interface nmcli to set up my wireless connection or my wired connection. That is not too much of a problem but since I did a backup of all my old network connections I had quite a list of connections too look for in order to find the uuid of the network I wanted to join and enable the network with the suitable command. So I wanted to delete all the connections from hotels, airports and places that I am not visiting anymore. Obviously I could have done this by hand. But its much more fun to do it automatically and on the long term it is really faster when you are mastering your bash tools (:
So here we go with a step by step explanation of the following command that will remove all your network connections that you have never used:

$ for i in `nmcli c | grep "never" | grep -o -- "[0-9a-fA-F]\{8\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{12\}"` ; do nmcli connection delete uuid $i ; done

ok let us first see the connections that I had in my manager

$ nmcli connection

which would give me the following list

the interesting part is the fourth column which is luckily saying never if a connection was never used. so that is an easy grep:

nmcli c | grep "never"

from this list I need the second colum in particular the uuids. I could have done this with some awk magic but I decided greping for uuids should be easier so lets pipe the output to another grep:

nmcli c | grep "never" | grep -o -- "[0-9a-fA-F]\{8\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{12\}"

as we can see the regular expression is really straight forward. there are two arguments given first of all -o that is to only output what was matched and not the complete lines and the — helps for greping hyphens. The cool thing is with having the web and search engines you don’t even have to build this regular expression on your own. Click on my search query for an blog article explaining the background: grep regular expression uuid
Next we have to iterate over the result and use it in the nwcli connection delete command. From the docu of nmcli we know

Usage: nmcli connection { COMMAND | help }
COMMAND := { list | status | up | down | delete }
list [id | uuid ]
status [id | uuid | path ]
up id | uuid [iface ] [ap ] [--nowait] [--timeout ]
down id | uuid
delete id | uuid

so the code should look something like:

nmcli connection delete uuid 954559e9-5f8c-4f9b-b2bc-36ff23f18d4a

only that 954559e9-5f8c-4f9b-b2bc-36ff23f18d4a will be replaced by all the uuids from my grep statements.
so let’s put this big grep in a loop and just echo everything to see if it is working. just use backticks around the grep and make a loop:

$ for i in `nmcli c | grep "never" | grep -o -- "[0-9a-fA-F]\{8\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{12\}"` ; do echo $i ; done

that looks great so replace the echo with the real command:

nmcli connection delete uuid $i

this will lead to the follwing final command which is identical to the one on the top of the article but just with some line breaks for better readability.

$ for i in `nmcli c | \
grep "never" | \
grep -o -- "[0-9a-fA-F]\{8\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{4\}-[0-9a-fA-F]\{12\}"` ; \
do nmcli connection delete uuid $i ; \
done

Now I only have a few connections in my network manager so that I can easily switch connections from the command line depending on where I am:

$ nmcli c
