Yields entries in the form of "/dev/hda1" etc. Use this if you are on a new system and don't know how the storage hardware (ide, sata, scsi, usb - with ever changing descriptors) is connected and which partitions are available. Far better than using "fdisk -l" on guessed device descriptors. Show Sample Output
13hwinfo --block --short -
Loop is needed if you have more then one card. Show Sample Output
4for I in `/sbin/lspci |awk '/VGA/{print $1}'`;do /sbin/lspci -v -s $I;done -
This command lists the names of your USB devices connected and what file in /dev they are using. It's pretty useful if you don't have an automount option in your desktop or you don't have any graphical enviroment. Show Sample Output
2ls -la /dev/disk/by-id/usb-* -
This command tell you if your hardware is 32 or 64 bits even if you install a 32bits OS on a 64 bits hardware. If your distro don't support the -q switch, try doing :
grep &>/dev/null '\<lm\>' /proc/cpuinfo && echo 64 bits || echo 32 bits2grep -q '\<lm\>' /proc/cpuinfo && echo 64 bits || echo 32 bits -
probably only works if you have one graphics card. used this: http://www.cyberciti.biz/faq/howto-find-linux-vga-video-card-ram/ as reference can be expanded, for example:
lspci -v -s `lspci | awk '/VGA/{print $1}'` | sed -n '/Memory.*, prefetchable/s/.*\[size=\([^]]\+\)\]/\1/p'will just get the amount of prefetchable memory compare to:lshw -C displaywhich does not give the size (it does give byte ranges and you could calculate the size from that, but that's a pain) Also uses a command which is not standard on linux; wheras lspci is a core utility provided by most systems Show Sample Output1lspci -v -s `lspci | awk '/VGA/{print $1}'` -
Find installed network devices. Show Sample Output
1sudo lshw -C network -
1dbus-send --session --print-reply --dest="org.gnome.SettingsDaemon" /org/gnome/SettingsDaemon/Power org.gnome.SettingsDaemon.Power.Screen.SetPercentage uint32:30
-
CPU flags: rm --> 16-bit processor (real mode) tm --> 32-bit processor (? mode) lm --> 64-bit processor (long mode)
1cat /proc/cpuinfo | grep " lm " > /dev/null && echo 64 bits || echo 32 bits -
Formats the output from `ioreg` into XML, then parses the XML with `xmllint`'s xpath feature. Show Sample Output
1ioreg -ad2 -c IOPlatformExpertDevice | xmllint --xpath '//key[.="IOPlatformUUID"]/following-sibling::*[1]/text()' - -
Avoids cat abuse ;)
0grep " lm " /proc/cpuinfo > /dev/null && echo "64-bit" || echo "32-bit" -
Info about Bluetooth devices. Show Sample Output
0hciconfig;hciconfig -a hci0;lsmod |grep bt;dmesg | grep tooth -
Gets the Hardware UUID of the current machine using system_profiler. Show Sample Output
0system_profiler SPHardwareDataType | awk '/UUID/ { print $3; }' -
0ioreg -d2 -c IOPlatformExpertDevice | awk -F\" '/IOPlatformUUID/{print $(NF-1)}'
-
-1ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6
-
-1uname -m
-
Prints the type of computer you have. I think this should be used more in distros and other applications because it is so easy to get. This can also be asked by tutorials as an easy way to get your base hardware. Some alternatives:
sudo dmidecode -s system-product-nameandsudo smbios-sys-info-lite | sed -n 's/^Product Name: *\(.*\)/\1/p'Show Sample Output-2cat /sys/devices/virtual/dmi/id/board_name -
CPU flags: rm --> 16-bit processor (real mode) tm --> 32-bit processor (? mode) lm --> 64-bit processor (long mode)
-4if [[ lm = $(cat /proc/cpuinfo | grep " lm ") ]] ; then echo "64 bits" ; else echo "32 bits" ; fi
