Running a script as root at bootup

  • 772

I have a simple script to help me do some power saving:

#!/bin/bash
echo 1 > /sys/module/snd_hda_intel/parameters/power_save
echo min_power > /sys/class/scsi_host/host0/link_power_management_policy
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs

I want this to run on every boot as root, tried running it by adding:

/bin/bash /root/power-save.sh

in

/etc/rc.local

and also tried by adding following to root's crontab:

@reboot /bin/bash /root/power-save.sh

no use..

linux ubuntu root boot

  1. You can run the commands directly in rc.local instead of running a script. Just put

    echo 1 > /sys/module/snd_hda_intel/parameters/power_save
echo min_power > /sys/class/scsi_host/host0/link_power_management_policy
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs

    in rc.local.
