[ubuntu] export path doesn't work on ubuntu 12.04

view story

http://ubuntuforums.org – Hi at all, I'm trying to launch a binary file form shell in this way: #/opt/some/binary/file/binaryfile but shell answer: #/opt/some/binary/file/binaryfile /opt/some/binary/file/binaryfile : no such file o directory but the path is ok and the binary file is in that path. I'm tried also: chmod 777 -R /opt/ without success. Where is my mistake? (Hardware)
