.@chris I’ve parsed a lot of things like this with awk / nawk / gawk.

Put multiple lines in an awk script (.awk) that match patterns and set variables.

Then after you e matched the last line, do what you want with the variables. E.g.

($1 == “Running”){
runningMode=$4
state=$7}

($1 == “Power”){
powerManagementMode=$5
print state, powerManagementMode, runningMode

runningMode=“”
state=“”
powerManagementMode=“”
}

The idea is match lines that should have known value(s) in specific field(s) and use set variables to the proper values on the matched line.

Once you see the last line (in a set) then use the variables and set the variables to default / control values.

I’ve had great success with this as a #sysadmin

This is just for an idea, all typose are my cats fault. Negative warranty provided. 😉


Spent some time tweaking #nginx a little to eke out a few milliseconds of performance. Makes a difference? Not really. Fun? Yes! #sysadmin #nerd


I’m looking for a template based way of reformatting data from a text form / mask to some variables. The input is “beautiful”, the output should be just variable names and values. I want to un-format.
Does any #sysadmin have an idea how to approach this in 2024, with as little additional tools as possible?
I didn’t touch that territory for a long time so I’m not coming up with a good idea except intuitively using #awk but I feel that there should be better approaches by now.

Ever wonder when your system last updated a package when using a Debian or Ubuntu Linux? Let's check Firefox, for example. Type this:

```
grep -B4 firefox /var/log/apt/history.log
```
