set $PATH via ./paths.sh

[pip010]

I want to set paths via my own script (paths.sh):

export PATH=$PATH:/usr/bin/python2.5:~/www/bin

export PYTHONPATH=$PYTHONPATH:/usr/bin/python2.5:~/www/site-packages

echo -e "PATH-->$PATH \n PYTHONPATH--->$PYTHONPATH"

mainly because I fo not have an access to my home folder, so no bash.rc

my question is why after running the script ./paths.sh
there is no effect!!

if I execute the commands manually one by one, it is all OK.

maybe I'm missing something in the script?

source your file, instead of running it, e.g.:

. paths.sh

[pip010]

hmm it works!
so whats the difference?

When you run it (./paths.sh), you are doing everything in a new shell (which then exist when the script completes). When you source it (. paths.sh), you are doing everything in your current shell. This is how profiles scripts work (/etc/bashrc, ~/.bashrc, etc.), they are sourced at login time.
