Bash formating string | Azure CLI | Etag | IfMatch | azure devops

So I am trying to automatically update an azure devops wiki using azure CLI. In order to do so I need to get the wiki etag:

az devops wiki page show\
        --path 'my_project - Slab Quality Prediction/test' \
        --wiki my_project.wiki \
        --query 'eTag'

Output:

"\"1156501f9cxxxxxbdca3456d6xxxxdd63\""

And if I manually copy this output and past in the command

az devops wiki page update\
    --path 'my_project - Slab Quality Prediction/test' \
    --wiki my_project.wiki \
    --version "\"1156501f9cxxxxxbdca3456d6xxxxdd63\"" \
    --file-path test.md \
    --encoding utf-8

It works perfectly.

Great, now just need to automate that, right?

etag=$(
    az devops wiki page show\
        --path 'my_project - Slab Quality Prediction/test' \
        --wiki my_project.wiki \
        --query 'eTag'
    )

az devops wiki page update\
    --path 'my_project - Slab Quality Prediction/test' \
    --wiki my_project.wiki \
    --version $etag \
    --file-path test.md \
    --encoding utf-8 \
    --debug &> thebug

Wrong, look at the error.

Error message:

Pre-condition `IfMatch` header provided in the request is an invalid page version. Please provide the version of the wiki page as the `IfMatch` header for the request.
Parameter name: IfMatch

If you look at the debug option, you can see why the error, it's because the etag it is not set correctly:

version that show on debug: ... '--version', '"\\"1156501f9cxxxxxbdca3456d6xxxxdd63\\""', ...
what should be: "\"1156501f9cxxxxxbdca3456d6xxxxdd63\""

I did not foud a way to right format this guy so the bash would understand.

In the end it was not needed the (""), so I just use the following commands:

etag=$(
    az devops wiki page show\
        --path 'my_project - Slab Quality Prediction/test' \
        --wiki my_project.wiki \
        --query 'eTag'
    )

az devops wiki page update\
    --path 'my_project - Slab Quality Prediction/test' \
    --wiki my_project.wiki \
    --version ${etag:3:-3} \
    --file-path test.md \
    --encoding utf-8
