I'm pretty sure that shouldn't be there ls -lart /usr/bin/\[ -rwxr-xr-x 1 root root 55784 May 4 12:22 '/usr/bin/[' Reproducible: Always
No, it's intended. It's shell test in non-builtin form similar to /bin/echo and such. e.g. /usr/bin/[ -n nonempty ] && echo yes Mostly same as /usr/bin/test bare a few difference (--help works with [).
Thanks, I didn't even think it might have been real - seen so many strange file names when scripting has gone wrong :D
