I need to unlock account through command line

geth --unlock 0x1554ce5a208c80D6087d73296E65405002cd640e --password /home/a/.ethereum/pa

but that command command just trying to start daemon, fail and close

Fatal: Error starting protocol stack: listen tcp :30303: bind: address already in use

how to execute correctly this command?

    You just have a program already listening on port tcp:30303, probably an already running geth instance in background. This is probably not a problem with unlock.
