I'd just like to mention the lbr uitility which I found which runs under linux

https://www.svgalib.org/rus/lbrate.html

lbrate extracts/decompresses files from the CP/M LBR format. (It can also list and test such archives.) It does this in an `unzip'-like manner, mostly hiding the details of individually compressed and renamed files, and transparently deals with the required decompression/renaming.

lbrate is also (I believe) the only non-CP/M program to fully support decompressing files from all three CP/M compression schemes (Q, Z, Y). With this in mind, it can decompress such files directly, treating them as if they were single-entry LBRs.

Yes, I use it all the time but under Windows.

On my github site you will find two further utilities which you may find useful. Both run under windows and linux.

mlbr at https://github.com/ogdenpm/mlbr
It supports a number of additional features as indicated below

Usage: mlbr -v | -V | [-x | -d | -z] [-D dir] [-f] [-i] [-k] [-n] [-r] [--] file+
-v / -V show version information and exit
-x extract to directory
-d extract lbr to sub directory {name} - see below
-z convert to zip file {name}.zip
-D override target directory
-f forces write of skipped library content
-i ignore crc errors
-I ignore crc errors and corrupt decompression
-k keep original case of file names (default is to lower case)
-n don't expand compressed files
-r recursively extract lbr, creates nested sub directories for -d or -z
-v show verison details and exit
-- terminates args to support files with a leading -
file+ one or more lbr, squeezed, crunched or crLzhed files
names can include * or ? wildcard characters
{name} is file with leading directory and extent removed

Listing of file details, including validation checks is always done
The -x or -d options allow files to be extracted
When files contain comments or are renamed to avoid conflicts
the details are written to a file {name}.info

mklbr at https://github.com/ogdenpm/mklbr
It supports creation of lbr files, including renaming and timestamping. Note it does not compress files itself
