path syntax?

Tavis · 09-01-2002, 02:17 AM

After not following instructions in 10.1 and losing most of my terminal prefs in switching to 10.2, i decided to follow instructions and set up the ~/Library/init/tcsh directory and put my aliases and path files in there. Now i can't figure out how to write the path file to get the shell to recognize it. I've tried set path= (blah blah blah), i tried set $path= (blah blah blah) and i tried just blah blah blah. nothing seems to work. I test this by quitting terminal and restarting it, since these files should be read by every new shell that is opened, but perhaps i need to log out and log back in to see the changes?

Try this: set path = ($path path_to_directory)

i.e. set path = ($path ~/Applications/bin) would add the ~/Applications/bin directory to your path.

This appends the new path to your existing path variable.

Go here:

for a simple tutorial on how to set and unset environment and shell variables.

I know i'm using the right syntax now, but i still get the default path when i use the echo command. I have the path file in ~/Library/init/tcsh/path. Is that the right place. Do I need to put the path file somewhere else?

Please see this hint.

Pay particular attention to this section:

Quote:


	It turns out that the files which used to live at: /usr/share/init/tcsh have been moved to: /usr/share/tcsh/examples/ With this change in path, the startup scripts fail to read the ~/Library/init/tcsh files. The README file in the examples directory gives the simple solution: This directory contains some useful tcsh files. In order to use this configuration: % echo "source /usr/share/tcsh/examples/rc" > ~/.tcshrc % echo "source /usr/share/tcsh/examples/login" > ~/.login % echo "source /usr/share/tcsh/examples/logout" > ~/.logout To do this system-wide, do the same instead to /etc/csh.cshrc, /etc/csh.login, and /etc/csh.logout. Once I ran the three "source" commands, my previously defined prompt, shortcuts and paths were back to normal.

And this section:

Quote:


	There is a typo in /usr/share/tcsh/examples/aliases. Change the line that says: if ("$TERM_PROGRAM" == "Apple_Terminal") then to: if ("$?TERM_PROGRAM" == "Apple_Terminal") then

Hi, don't worry about the tcsh-path in MacOSX 10.2!
Look at this site, download the files and place the .tcsrc-files in your home-directory or follow the install-instructions:
http://tcshrc.sourceforge.net/
Now you can have all your custom tcsh-configurations back.

I've run all of the echo commands, I've fixed the typo in my alias file, and i double checked that there are no superfluous spaces in the path to ~/Library/init/tcsh/path. And i still only get the default path. Any other ideas?

Tavis,

I've noticed on several machines that I was not able to run the echo command directly. I had to use a text editor on the files in question. This is most likely because the files already existed. I'll walk you through one example - you can extrapolate the rest.

Code:

[hschickel1:~] hugh% more /etc/csh.cshrc
# System-wide .cshrc file for csh(1).

if ($?prompt) then
        set promptchars = "%#"
        if ($?tcsh) then
                set prompt = "[%m:%c3] %n%# "
        else
                set prompt = "[%m:%c3] `id -nu`%# "
        endif
endif
[hschickel1:~] hugh%

This is the original csh.cshrc file. We want to change it. So...

sudo mv /etc/csh.cshrc /etc/csh.cshrc.original - change the name of the file

sudo pico /etc/csh.cshrc - open the pico text editor and create the file /etc/csh.cshrc

Type or paste:
source /usr/share/tcsh/examples/rc

<control>-x - to exit
y - to accept
<enter> - to write the file

Code:

[hschickel1:~] hugh% more /etc/csh.cshrc
source /usr/share/tcsh/examples/rc
[hschickel1:~] hugh%

Do the same for each.

Hugh
