finding environmental variables

Operating system: Linux: Environment: Variable: Path: Set: How to set the PATH variable in Linux?

The PATH environment variable contains a list of directories used by
the shell to locate
executable files typed on the command line.

If you then type a command on the command line, each of this
directories is searched,
from left to right, until the executable with the same name is found.

---

The format of the path in general is:

PATH=::...

so a list of directories separated by colons

---
---

To set the PATH environment variable:

---

Steps: Overview:

1. -Open a console

2. -If necessary login with the wanted userid:

1. type

su

and supply a password

2. To check the current value of the PATH
environment variable, type:

echo $PATH

that will show the current path

e.g.

/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/roo
t/bin

3. -To set the new path

1. to APPEND your new directory at the END of the current path
type the command:

PATH=$PATH:

e.g.

PATH=$PATH:/mydirectory

will add '/mydirectory' at the end of the existing
path

2. to APPEND your new directory at the BEGINNING of the current
path
type the command:

PATH=:$PATH

e.g.

PATH=/mydirectory:$PATH

will add '/mydirectory' at the beginning of the existing
path

3. to OVERWRITE the current path
(so use with caution, possibly write down the old path first),
type the command:

PATH=

e.g.

PATH=$HOME/bin:/bin/:/usr/bin

---

PS do not use spaces

---

$HOME/bin

and

/bin

and

/usr/bin

trying to install GTK+ 2.4 on mandrake 9.2, having quitte a few problems...it asks me to modify my LD_LIBRARY_PATH environment variable.....where can i find this, and what am i supposed to modify it to?
It probably isn't set at all ...

As for the value: if it wants you to set it, it
is likely to say what to set it to as well...

export LD_LIBRARY_PATH=


To see whether it actually is set try
echo $LD_LIBRARY_PATH
or
env | grep LIBRARY
