I have found the term "LSB executable" or "LSB shared object" in the output of the
file command in Linux. For example:
$ file /bin/ls /bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=4637713da6cd9aa30d1528471c930f88a39045ff, stripped
What does "LSB" mean in this context?
