Description LLaq2YZE 2019-11-26 01:06:14 UTC 
BusyBox prints help text instead of compressing the file:


$ busybox lzma myfile 
BusyBox v1.31.1 () multi-call binary.

Usage: lzma -d [-cfk] [FILE]...

Decompress FILE (or stdin)

        -d      Decompress
        -c      Write to stdout
        -f      Force
        -k      Keep input files


I'd expect that BusyBox creates myfile.lzma and exits without error.

bbox does not support lzma *compression*, it can only decompress. Help text shows that -d option is mandatory:

$ busybox lzma myfile 
BusyBox v1.31.1 () multi-call binary.

Usage: lzma -d [-cfk] [FILE]...

Decompress FILE (or stdin)

        -d      Decompress
