LABEL(1)

NAME
label, awd - set window label

SYNOPSIS
label string
awd [ sysname ]

DESCRIPTION
Label sets the label of the current win (see acme(1)) or X terminal window (e.g., 9term(1) or xterm(1)) by echoing a special control sequence to standard output.

Acme and 9term windows assume the label is a directory name. When unrooted file names are plumbed in the window, they are evaluated relative to the directory named in the label.

The label may have a suffix /-sysname, which is not interpreted as part of the directory during plumbing. Awd sets the window name to the current directory with a /-sysname suffix, using the name of the current system by default.

EXAMPLE
One can use the following sh(1) function to keep the label up-to-date in response to cd commands:

        _cd () {
        	\cd "$@" &&
        	case $- in
        	*i*)
        		awd
        	esac
        }
        alias cd=_cd
        cd .

Rc(1) installs a similar fn cd at startup if there is not already a function named cd:

        fn cd {
        	if(builtin cd $1){
        		if(flag i) $PLAN9/bin/9 awd || status=''
        		status=''
        	}
        }
