To concatenate two or more PDF files together into one, try
# gs -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=concatenated.pdf file1.pdf file2.pdf [file3.pdf [...]]
With the -dBATCH -dNOPAUSE option, ghostscript won’t show a prompt and you won’t have to press return after each page. Comes in handy if the PDFs are long.
On my Gentoo notebook, stopping cpufreqd fails:
# /etc/init.d/cpufreqd stop * Stopping CPU Frequency Daemon ... [ !! ]
It seems that start-stop-daemon fails to terminate the cpufreqd processes, so let’s help it a bit. Simply add the following bold line to the stop() function in your /etc/init.d/cpufreqd script
stop() {
ebegin "Stopping CPU Frequency Daemon"
kill -9 `ps -A | grep cpufreqd | sort -n | head -n 1 | awk ‘{print $1}’`
start-stop-daemon –stop –exec /usr/sbin/cpufreqd
eend ${?}
}
Now cpufreqd should shut down nicely:
# /etc/init.d/cpufreqd stop * Stopping CPU Frequency Daemon ... [ ok ]
