How to cut part of line?

Grzegorz Michalak

I need to cut line in specific moment, I want to display GPU name, but only name, nothing else.

inxi -Gx | grep Device showing:

Device-2: NVIDIA GK107GLM [Quadro K1100M] vendor: Dell driver: nouveau

I want it to show something like this

NVIDIA GK107GLM [Quadro K1100M]

How to cut this to show only name? Is there a way to print range, in this case from word Device to word vendor.

Please [edit] your question and show the example output of `inxi -Gx | grep Device` and the expected output, [formatted as code](https://stackoverflow.com/editing-help#code). This question is about shell programming / text processing and not specifically related to Ubuntu, so it might better fit on https://stackoverflow.com/

Tryt to do it this way:

inxi -Gx | sed -n 's/.*Device-.*: \(.*\) vendor.*/\1/p'

Yes, thats it! Thank you very much. Can you describe how this works? This command

Sure. 1. -n param suppresses automatic printing of pattern space(no auto output from sed command) 2. sed is looking for this pattern `.*Device-.*: \(.*\) vendor.*` 3. `/\1/` - sed replaces all the matched line to the first match group (a part of pattern in brackets `(.*\)`) 4. `/p` param in the end prints the current pattern space( print matched lines)

Something like:

D=$(inxi -Gx | grep Device)

if [[ $D =~ ^Device-2:([[:print:]]*)vendor:([[:print:]]*)driver:([[:print:]]*)$ ]]
then
  echo "Found Device: ${BASH_REMATCH[1]}"
else
  echo "Did not find device"
fi

What version of bash are you using? (`bash --version`)

Grzegorz Michalak

5.0.3. it should work on newer bash?

Wayne Vosberg

It does work with 5.1.4(1). Looking back at the change log regexp matching and BASE_REMATCH *may* be new as of 5.1.

maybe you missed semicolon `]]; then`

I just realized I have a RaspberryPI with bash 5.0.3(1). It works there as well. Are you sure you entered the `if [[ ... ]]` line correctly? If so, try adding `set -x` to the beginning of the script - the output then may provide a clue.

inxi -Gx | grep Device | cut -d ':' -f 2 | sed 's/ vendor//'

This cuts the output into fields using ":" as a delimiter, then it gives you the second field. Use sed then to strip the specific word off the end.

If you know the length then you can cut a range using cut, see man cut for details.
