Does anyone know how to view and modify your library path?

view it by:
cat /etc/ld.so.conf

after changes invoke:
/sbin/ldconfig



sometimes this path is in LD_LIBRARY variable

when you say `view`, do you mean list the directories in your path, or simply list the files in /lib ?

Well that depends on what PATH you want to set. If you know the name of your variable then figure out what shell you are running (ksh, csh, bash... etc). If you don't know that then type 'echo $SHELL' and that should output the default shell that is used (more than likely bash). If it's bash... then you do the following, however, remember to replace PATH with the environment variable you intend on modifying:

export PATH=$PATH:/new/path/added/ <enter>

And that should work... to check type echo $PATH and see if your path has been added.

If you have a csh shell then you can do the following:

setenv PATH=$PATH:/new/path/added/ <enter>

Now these paths won't be permanent... if you want to do this permanently then put these lines your .cshrc or .bashrc files.

I mean how do you add a path (like for your PATH environment, its export PATH= $PATH/dir/).

I've got a similar problem, I can't get the path changes to save, and I don't have a .tschrc file, only .bashrc and .bash_profile. I'm quite sure that I'm running tcsh, cos when I type echo $SHELL, it returns /bin/tcsh.

How can I add path changes to .tschrc if I don't have one?

stolen thread

make one.
emacs ~/.tschrc
or change to bash
edit /etc/passwd
make for your username like
username:x:<number>:<number>::/home/username:/bin/bash

better to add the lib path to /etc/ld.so.conf
and as root run ldconfig
that to set the lib path variable

LD_LIBRARY_PATH
for runtime lib path

is usefull but an older and slower way of doing it
ld.so.conf is compiled and cached (faster and smarter)
developers use LD_LIBRARY_PATH mostly for temporary changes for testing

I don't seem to be able to make this work. I've made a .tcshrc file, which looks a bit like this:
################################################################
# .tcshrc

# User specific aliases and functions

alias rm 'rm -i'
alias cp 'cp -i'
alias mv 'mv -i'

# Source global definitions
if [ -f /etc/tcshrc ]; then
. /etc/tcshrc
fi

################################################################

Now when I open a shell, i get this message:

if: Expression Syntax.

What's wrong with my if statement? Have I missed something out?

Also, I need to add these statements to the .tcshrc in order to get a program to run:
setenv LD_LIBRARY_PATH $HOME/EMAN/lib
set path = (. $HOME/EMAN/bin $HOME/bin /bin)

But when I add these to the .tcshrc nothing changes. What exactly am I doing wrong?
