I’m having trouble logging in using Google SDK Compute SSH on a Mac Terminal.

Every time I log in to Google Cloud, it’s using the Chromium.
Set BROWSER env to Firefox instead.

You can run MySQL commands from the terminal by using -e switch. Here are a few examples.
mysql -u username -p -e "create database mydb" mysql -u username -p -e "use mydb" mysql -u username -p database -e "select * from mytable" |
mysql -u username -p -e "create database mydb" mysql -u username -p -e "use mydb" mysql -u username -p database -e "select * from mytable"
If you have .mycnf configured, you can omit the username and password.
mysql -e "create database mydb" mysql -e "use mydb" mysql -e "select * from mytable" |
mysql -e "create database mydb" mysql -e "use mydb" mysql -e "select * from mytable"
To run multiple commands from a single line, separate the commands using a semicolon.
mysql -e "create database somedb; use mydb; select * from mytable;" |
mysql -e "create database somedb; use mydb; select * from mytable;"
Here’s how to format a USB drive on Linux.
Plug in the USB drive to see mount point.
# scan for all drives df -Th Filesystem Type Size Used Avail Use% Mounted on /dev/sdc1 fuseblk 30G 66M 30G 1% /media/ulysses/451B99AF225B48EC |
# scan for all drives df -Th Filesystem Type Size Used Avail Use% Mounted on /dev/sdc1 fuseblk 30G 66M 30G 1% /media/ulysses/451B99AF225B48EC
Unmount USB drive.
umount /dev/sdc1 |
umount /dev/sdc1
Choose a file system type and run the appropriate format command.
# nfts format mkfs.ntfs /dev/sdc1 # vfat format mkfs.vfat /dev/sdc1 # ext4 format mkfs.ext4 /dev/sdc1 |
# nfts format mkfs.ntfs /dev/sdc1 # vfat format mkfs.vfat /dev/sdc1 # ext4 format mkfs.ext4 /dev/sdc1
Here’s a dd command to display sequential write throughput from the command line.
time dd if=/dev/zero of=/mounted_backup_volume/zero.raw bs=1M count=512 status=progress |
