I came across this problem now several times and I would like to find a way to automate/script this things that involves a change of identity or environment (I am not sure how to call that precisely).
An easy example would be a script where a part has to be executed with su
. (make install
for instance). To achieve this one could use sudo
. However there are other environment changes that do not have such an escape solution. Probably well known is the python virtualenv where one could easily imagine a script like
source virtEnv/bin/activate
python myScript.py
or simply a script that invokes screen
. Now I am compiling gstreamer which I would like to automate in a script, because I will have to deploy this installation in several other computers later
for i in gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly gst-python gnonlin gst-ffmpeg
do
gst-head
cd ./$i
git checkout tags/1.1.1
./autogen.sh
make -j7
exit
done
Where gst-head
is the gst-uninstalled
script that loads a local pkg_config (if I am right) and puts me in a separate environment. If I put that in a script the script will stop its execution there and continues once I do exit
from that environment.
make
not executed? What does not work in the script you have posted?
