Sorry, Chris, I just received this.
I'm not sure. Bourne compliant shells are going to read /etc/profile but it
may be a matter of the implementation for the ~/.profile file. Does anyone on
the list know the answer to Chris' question?

I've found that bash is happier when I wrap ANSI (or ANSIesque)
escape and control sequences inside \[ . . . \]. To quote from the
bash man page:
\[ begin a sequence of non-printing characters, which
could be used to embed a terminal control sequence
into the prompt
\] end a sequence of non-printing characters

ok, my head hurts now. This explains why when I forget that the
cmd shell I'm in didn't start from bash that bash looks wierd when
I start it....
iow in bash.exe:
if (args.contains("--login")) {
source = {"/etc/profile", "~/.profile"};
} else {
source = "~/.bashrc";
}
ANYWAY... the circumstance I'm concerned with was the default bash
shell that comes up when the user clicks on that funky little Cygwin
icon on their desktop. So '--login -i' are the arguments; in which
case the pattern is:
/etc/profile sources ~/.profile
/etc/profile sources ~/.bashrc
bash sources ~/.profile
(I guess since I don't have a ~/.bashrc I never noticed it
wasn't being run twice. ;)
In which case I'd think the 'fi' element in my changed /etc/profile
can move up one line:
if [ "$SHELL" != "/bin/bash" ]; then
test -f ./.profile && . ./.profile
fi
test -f ./.bashrc && . ./.bashrc

No, it doesn't always. If --login then ./.bashrc is not performed but
./.profile is, and without --login ./.bashrc is performed but not ./.profile.
Also, without --login the /etc/profile isn't performed and shouldn't be a
concern.

environment is a clean install of 1.1.4 from the "latest"
as of 7 Sept, window is set to 132 columns wide, $COLUMNS is
also set to 132. PS1 is set to:
'<0x1b>]0;\w<0x07><0x1b>[1m<0x1b>[34m\w<0x1b>[0m $ '
cd /tmp
mkdir -p
one/two/three/four/five/six/seven/eight/nine/ten/eleven/twelve/thirteen/fourteen/fifteen/sixteen/seventeen/eighteen/nineteen/twenty/twentyone/
{wrapping bug #1: mkdir command is wrapped between x and t of sixteen,
at column 110}
cd one/
cd two/
cd ...
repeating this by means of: "up arrow, esc, backspace, tab, enter"
after cd ten you'll see wrapping bug #1b,
command is wrapped at column 61
after cd eleven you'll see wrapping bug #2,
prompt is wrapped at column 58
each cd after that you'll see the prompt is
wrapped *earlier* than before
until after cd eighteen, when it tries to wrap at
a negative column and the result is some binary
looking junk in the prompt. This is also the point
where the titlebar stops being in sync; it appears
that from here forward each prompt begins with the
trailing junk that's been truncated from the titlebar.
if the titlebar manipulations are removed from PS1 then
everything goes well up until cd eighteen and nineteen,
where there are some issue with crlfs being left out, but
once you get past there then the prompt is properly wrapped
and everything is ok.
if all ansi codes are removed (PS1='\w $') then there are
no problems at all.
On a related note:
the default /etc/profile sets up these ansi codes by
default for all terminals, I'd suggest that at the bare
minimum these be skipped if the term type is incapable.
I've set mine up as:
if [ "$TERM" == "cygwin" ]; then
PS1='' #cygwin version with ansi codes
else
PS1='\w $'
fi
export PS1
and as long as I'm in that file, I just saw the other
patch I put in my copy....
if [ "$SHELL" != "/bin/bash" ]; then
test -f ./.profile && . ./.profile
test -f ./.bashrc && . ./.bashrc
fi
this has the advantage for those who run bash of not
sourcing these files twice, as bash does so itself.
