NAME
talk - talk to another user
SYNOPSIS
talk talk_party [ttyname ]
DESCRIPTION
The talk utility is a two-way, screen-oriented communication program.
The command argument talk_party can take one the following forms:
user
user@host
host!user
host:user
host.user
where user is a login name and host is a host name.
The optional command argument, ttyname, can be used to specify the terminal to be used when contacting
a user who is logged in more than once. In absence of this argument,
talk will try to contact the user on
the user’s most recently used terminal.
When first invoked,
talk sends the following message to the party it tries to connect to (callee):
Message from Talk_Daemon@ callee_host
...
talk: connection requested by caller@caller_host
talk: respond with: talk caller@caller_host
At this point, the recipient of the message can reply by typing:
talk caller@caller_host
Once communication is established, the two parties can type simultaneously, with their output displayed in
separate regions of the screen. Characters are processed as follows:
• Typing characters from LC_CTYPE classifications print or space will cause those characters to be sent
to the recipient’s terminal.
• Typing <control>-L will cause the sender’s screen to be refreshed.
• Typing the erase, kill or kill word character will delete the last character, line or word on the sender’s
terminal, with the action propagated to the recipient’s terminal.
• Typing the interrupt character will terminate the local talk utility. Once the talk session has been ter-
minated on one side, the other side of the talk session will be notified that the session has been ter-
minated and will be able to do nothing except exit.
• Other non-printable characters typed on the sender’s terminal are converted to printable characters
before they are sent to the recipient’s terminal.
Permission to be a recipient of a
talk message can be denied or granted by using the mesg utility. How-
ever, a user may need other privileges to be able to access other users’ terminals. The
talk utility will fail
when the user lacks the appropriate privileges.
