raspberryTools

Note:

There is a very useful tools collection available, called usb-tools Running Raspbian from USB Devices : Made Easy which contains four very nice tools called usb-boot, sdc-boot, mbr2gpt and set-partuuid.

raspberryTools

Collection of some useful tools for Raspberry Pi. For sample outputs of the tools click the links.

raspiNetInfo.sh - Collect network information for people who want to help in network problem determination and test for common network configuration errors
checkWLANAndRestart.sh - Check on regular base for WLAN connection and either restart network interface or reboot Raspberry if there is no connection
checkThrottled.sh - Check Raspberry throttled bits with vcgencmd get_throttled and display their meaning if throtteling happened since boot or since last script invocation
testCPUTemperature.sh - Generates 100% CPU load on a Raspberry and monitors the CPU temperature. Useful to test the effectiveness of a heat sink and/or fan.
retrieveTerrabytesWritten.sh - Either retrieves the Total Bytes Written of all existing SSDs on the system or a specific SSD. Helps to get an idea when the SSD will reach it's end of life.
retrieveLifetimeWrites.sh - Either retrieves the LifetimeWrites of one or all existing ext2/ext3 and ext4 partitions. Helps to get an idea when the SD card or disk will reach it's end of life.
findRaspis.sh - Scan the local net for Raspberries and print the IPs, macs and hostnames sorted by IP. A config file can be used to add an additional descriptions for the hostname
smsRelay.py - Receives all SMS and forwards them to an eMail. UMTS stick and python2 required. Depends on Python2 and therefore is outdated. Use smstools and eventhandler file smsevent instead.
checkPARTUUIDsInDDImage.sh - Retrieve PARTUUIDs of Raspberry dd Backup image partitions /boot and / and check if they match in /boot/cmdline.txt and /etc/fstab
syncUUIDs.sh - Check whether /boot/cmdline.txt and /etc/fstab on a device match the UUIDs or PARTUUIDs used on the device partitions. Option -u will synchronize the files. Useful when an image was cloned to another device and fails during boot.
raspiKernelInfo.sh - Retrieve info about the running system on a Raspberry
raspiHandleKernels.sh - Delete and reinstall unused kernels in a bookworm image to speed up apt upgrade processing

findRaspis.sh

findRaspis.sh
Scanning subnet 192.168.0.0/24 for Raspberries ...

IP address      Mac address       Hostname (Description)
192.168.0.8     b8:27:eb:b4:e8:74 troubadix (Networking server)
192.168.0.10    b8:27:eb:3c:94:90 idefix (Homeautomation server)
192.168.0.12    dc:a6:32:8f:28:fd asterix (LAN server)

syncUUIDs.sh

Check UUIDs (UUIDs are OK):

sudo ./syncUUIDs.sh  /dev/mmcblk0
/dev/mmcblk0p1 has PARTUUID 5e1ad0e3-01
/dev/mmcblk0p2 has PARTUUID 5e1ad0e3-02
Boot PARTUUID 5e1ad0e3-01 already used in /etc/fstab
Root PARTUUID 5e1ad0e3-02 already used in /etc/fstab and /cmdline.txt

Check UUIDs (UUIDs are not OK):

sudo ./syncUUIDs.sh  /dev/mmcblk0
/dev/mmcblk0p1 has PARTUUID 5e1ad0e3-01
/dev/mmcblk0p2 has PARTUUID 5e1ad0e3-02
PARTUUID 1e1ad0e3-01 should be updated to 5e1ad0e3-01 in /etc/fstab on /dev/mmcblk0p2
PARTUUID 1e1ad0e3-02 should be updated to 5e1ad0e3-02 in /etc/fstab on /dev/mmcblk0p2
PARTUUID 1e1ad0e3-02 should be updated to 5e1ad0e3-02 in /cmdline.txt on /dev/mmcblk0p1

Update UUIDs (UUIDs are not OK):

sudo ./syncUUIDs.sh  -u /dev/mmcblk0
/dev/mmcblk0p1 has PARTUUID 5e1ad0e3-01
/dev/mmcblk0p2 has PARTUUID 5e1ad0e3-02
Creating fstab backup /etc/fstab.bak on /dev/mmcblk0p2
Updating PARTUUID 1e1ad0e3-01 to 5e1ad0e3-01 in /etc/fstab on /dev/mmcblk0p2
Updating PARTUUID 1e1ad0e3-02 to 5e1ad0e3-02 in /etc/fstab on /dev/mmcblk0p2
Creating cmdline backup /cmdline.txt.bak on /dev/mmcblk0p1
Updating PARTUUID 1e1ad0e3-02 to 5e1ad0e3-02 in cmdline.txt on /dev/mmcblk0p1
