Given these functions:
TTY=`tty | sed -e s:/dev/ttyp::`
host=`hostname | tr a-z A-Z | sed -e s/.BBN.COM//`
function pwd() {
# This has two ESCAPEs and one BACKSPACE in it.
echo -n "^[]lBASH@${host}(${TTY}):$PWD^[\^H"
}
function cd() {
builtin cd $*;
pwd;
}
When I say "type pwd" my window banner gets all messed up.
That's because you didn't use the -e flag on the echo command which
would allow you to type in those escapes in ASCII representation:
function pwd () {
echo -n -e "\033]lBASH@${host}(${TTY}):$PWD\033\010"
}
Thanks for the neat function!
Also, while I'm here:
function bxmf() {
make -k "$@" >foo 2>&1 &
# It doesn't seem quite right that this next line is really needed...
: ;
}
It isn't. You have mentioned this a couple of times. In 1.03, you
don't even need to end the list with a terminator, but even in prior
versions the newline character (or ampersand) is enough.
function bxmf () { make -k "$@" >foo 2>&1 & }
