This si my shell (bash) script:
# shell script to install all the packages in ~/R/allpackages,
# to ~/R/allinstall . Should be run from ~/R/Recommend .
#
for FILE in ~/R/allpackages/*z
do
if [ -f $FILE ]
then
nice R CMD INSTALL --library=~/R/allinstall --no-test-load \
--no-configure --html --no-libs --no-exec --resave-data $FILE \
|| echo "Problems encountered during processing of $FILE" &
fi
done
#
As you can see, I did spawn the subprocesses with nice!
Why didå nt that work?
Any tips on how to write the script so that it becomes "nice"?
