Try this.

At terminal prompt,

vi .cshrc

type SHIFT g and return
type O
type alias cd 'cd \!*; echo -n "^[]0;`pwd`^G"'
type ESC
type SHIFT zz

shift and esc - press correct keyboard

to type ^[

CTRL-v and ESC

to type ^G

CTRL-v and CTRL-G

Quit terminal and relaunch~

You can see the title window is dynamically changes when you change your working directory.

Sorry for confusion. To make this easy, I made a small script.

download 'termtip' from

homepage.mac.com/wujekim

% chmod +x termtip
% ./termtip
% source ~/.cshrc

You can remove 'termtip' file now. Don't run termtip twice.

Maybe if you explained what this did I would try it. However, for all I know this could be one long "rm -rf /"

So what does it do?

Don't see why or how this could work.

In fact, it doesn't.

How's that for the Gratuitous Stupid Post of the Day Award?

Thank you for enlightenment. Next time, don't think with your hands.

Now, can somebody perhaps explain what those commands actually do, step by step? Thank you.

cwasko · Jan 28, 2002, 11:02 AM

Alrighty, well, after looking at this, there are some problems with the initial post.

I got it to work, and this is what I did:

<BLOCKQUOTE>code:<HR><pre>
% cd ~
% vi .cshrc

<command>SHIFT-o</command>
alias cd 'cd \!*; echo -n "^[]0`pwd`^G"'
cd ~
<command>ESC</command>
<command>SHIFT-zz</command>
[/code]

Where I've deliniated the areas with the 'command' tag, simple type these commands in with no returns after completion; obviously do not type the <command> stuff.

As originally stated:

To get the '^[' sequence, type: CONTROL-v ESC
To get the '^G' sequence, type: CONTROL-v CONTROL-g

Now, for a better description of what this does: When you have a terminal window open, this will put the path of the current directory in the title bar of the window. This way, if you have multiple terminal windows open, then you can tell which one is in which directory without having to 'remember'.

For those that care, this is what I changed from the original post: First, I have the user do a 'cd ~'. This ensures that the user is in their root directory, which is where the .cshrc file needs to be for this to work. Then, I added the '*' to the aliased cd command. The '*' is required and this is what 'copies' the arguments from the as-typed 'cd' command to the new aliased 'cd' command. I also added a 'cd ~' at the end of the .cshrc file. This makes sure that the user is in their home directory when a new terminal is open and it also makes sure that the directory is prepended to the Terminal Window's title.

Well, just by looking at it, you have a keyboard virus. Email me and I'll arrange for you to have your machine sent to my home to be disinfected. Don't worry, it happens to all users once in a while. OK?

What passes arguments in Bash? This works for me in cshrc, but in bash I get
 bash: cd: 1*: no such file or directory

Well, eventhough it may seem like I know something, I figured it out through trial and error. I did look up a few things to figure out that the '*' was required for csh. You could try just deleting the '*' for Bash.

netgo · Jan 28, 2002, 02:55 PM

Thank cwasko.

You can change pwd to proper unix command to change the window title.

Actually this tip is Xterminal escape sequence and works well in Aqua.

Xeo · Jan 28, 2002, 03:38 PM

Is this supposed to work for tcsh as well as csh? I assumed it would but I can't get it working. I know how to edit my .cshrc file so that's not the problem. I get a weird looking prompt (only because echo isn't printing a newline). Here is what comes before my regular prompt:

^[]0;/Applications^G

The only thing I can assume is that it won't work for tcsh. I used the exact command cwasko posted.

[edit: I just tried it with csh instead of tcsh. Same problem. Doesn't work.]

netgo · Jan 28, 2002, 03:57 PM

xeo, it should work in both csh and tcsh environment. Please make sure that you correct escape sequence. ctrl-v ctrl-esc and ctrl-v ctrl-g

Don't copy and paste. You will lose control character info.

rantweasel · Jan 28, 2002, 08:55 PM

A alternative to this, for tcsh users, is to add the following line to your .tcshrc file:

set prompt = "%n@%m %~>"

You'll get a prompt that looks like:

<BLOCKQUOTE>code:<HR><pre> username@hostname /current/working/directory/using/tilde/for/home> [/code]

it's nifty. Man tcsh (or whatever shell you prefer) for many more variations on this...

Xeo · Jan 28, 2002, 09:21 PM

Ahh, I see. I copied and pasted. I didn't realize I needed specific keyboard input like that. Anyway it still didn't work for me. I only tried once so it was probably a mistype again. However, I downloaded that shell script and now it works.

There is a bug in the shell script though. It doesn't exactly copy the `pwd` into the .cshrc file. Since it's a shell script, it first executed that as a command and included the result. Every window had the path to my home directory in it. I manually edited my .cshrc file to include `pwd` in place of that path and now it works.

You should fix that shell script though.

Xeo · Jan 28, 2002, 09:25 PM

I have a custom prompt too. I like having only what I need as a prompt. I recommend using ManOpen or manThor or something like that to view the man pages on tcsh and other shells. They are very long and trying to view them in the terminal can be difficult. You can search for "prompt" with those GUI apps too and get you right where you want to be.

When will thou blasphemous vi users realize that The One True Editor is emacs!

Seriously, I never use vi, I use either emacs or TextEdit, and I may consider using pico, but vi has always felt so kludgy. Please change the instructions to the following:

<BLOCKQUOTE>code:<HR><pre>cd ~/
open .tcshrc[/code]

then add the following text to the file:

<BLOCKQUOTE>code:<HR><pre>Insert Text Here[/code]

so that it is more generally understandable.

Thanx

vi is too little, emacs is too much. Pico is juuust right!

And for a change of pace, I put
<BLOCKQUOTE>code:<HR><pre>
alias bbedit 'open -a /applications/BBEdit/BBedit'
[/code]
in my aliases.mine file and open files in bbedit from the command line. It roxxors.

I like the idea of having the path in the title. Having a prompt that long is kind of a bother for me.

You know with BBEdit 6.5 there is the bbedit command line tool.

Wevah · Jan 29, 2002, 12:57 AM

Yep, and it works much better than using the above alias...

I'm not very good at terminal command stuff. But I like the simplicity of this. I also like the permanence of the .cshrc file. What would I have to type in the ..cshrc file to get the above prompt permanently?

Thanks!

exactly that:

set prompt = "whatever you like"

it's your .cshrc file yeah, not ..cshrc file. That was probably just a typo I know but just in case...

Awesome! I didn't realize that the .cshrc file was always automatically read to the terminal. Does that mean I could instruct it to open a telnet prompt or something like that?

I just tried it and it works! I guess what I'm asking is: Does each line in the .cshrc file represent a terminal command/script? And if so, how do you put pauses in? Also, can you specify that only the first terminal window you open runs a particular script?

Thanks again. This is like candy!

The lines in the .cshrc file are the exact same format as you'd type them on the command line if you were doing it manually.

All the commands are automatically run whenever a new terminal is opened. This means you COULD set a command to telnet to some other machine, but you'd telnet to that machine EVERY TIME you opened a new terminal - probably not what you want.

You can't add pauses because if you did you'd have to wait for the entire .cshrc file to finish before you got your prompt. This means if you have a 1 minute pause in your script, you'd be waiting at least one minute before you were able to do anything on the command line, each time you opened a terminal window.

You can add logic to the script to conditionally run commands based on whatever criteria you decide. A good book on shell scripting is a wonderful read

wil · Feb 2, 2002, 01:21 PM

What I'd like to do is have the prompt mirrored in the window title. Terminal windows could be stacked but the current state of each would be easily spotted by glancing at their titles. Not sure how to go about it though!

netgo · Feb 2, 2002, 04:40 PM

Will, after run my small script termtip, change 'pwd' to 'echo $prompt' it will display your prompt on window title.

Mine is:

set prompt="(%c05): "

Very close to yours. I prefer the space afterwards so what I type doesn't attach directly to the prompt. I would prefer [] instead of () but it was a compromise my roommate and I had.

Xeo · Feb 2, 2002, 06:02 PM

Originally posted by netgo:

set prompt = "\! `whoami`@`hostname` : "

My question is why not just use the built in representations of "whoami" and "hostname" unless you aren't using tcsh.

`hostname` could be replaced with %m for the hostname up to the first dot or %M for the whole thing.

`whoami` could be replaced with %n.

That's why these shortcuts are there. The whole list of shortcuts are in the man pages of tcsh.

even better is:

cwdcmd is a command that is run every time the current directory is changed. This way the window title is updated, not just when you use cd, but also on pushd and popd.

Optimized version:

No embedded control characters or backquoted pwd command.

Granted, but only a small few Mac users will appreciate this and make use of it (but i assume many more will understand how useful it can be).

tinrib · Mar 28, 2002, 09:56 PM

can I have the hostname of the computer I am currently logged into (via SSH) in the titlebar? I tried adding $HOSTNAME instead of $PWD but of course once I am logged into another computer it doesn't work! (duh!).

This would be really cool as I often am logged in to 4 or 5 different servers at a time.
