I found a file named "[" in the /usr/bin directory. Performing a file on this gives: "[: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=0x6cd5d3670a4730dab4dd427c82783e01eccf922b, stripped"
Does anyone know if this is a legitimate file? I've never seen a file name like this.
I'm running a System 76 Bonobo with 13.04.
