Sometimes learning a new thing can be the result of my innate curiosity<\/a>.<\/p>\n\n\n\n

If you’re a frequent reader on Both.org, you probably already know that I’m rather obsessive about backups<\/a>. I make two backups of every computer on my network each day, one on an internal hard drive and one on an external USB HDD. I just recently added an external USB HDD for a monthly backup.<\/p>\n\n\n\n

Early this morning, as I write this, I was checking to verify that all three backups were created and could be properly accessed in case I needed to restore a file, a directory, or an entire filesystem. Verifying that backups can be accessed is a critical part of any backup plan. You do test that, don’t you?<\/p>\n\n\n\n

After performing my tests, I needed to unmount the three devices. Being the lazy SysAdmin<\/a>, I decided I would try unmounting all three with a single command using file globbing<\/a>, A.K.A, the wildcards * and ?. The umount man pages don’t state whether wildcards will work, but most Linux commands can use wildcards. So I tried it.<\/p>\n\n\n\n

# umount \/media\/*<\/strong><\/code><\/pre>\n\n\n\n
This worked perfectly and unmounted all three hard drives.<\/p>\n\n\n\n
Note that I also tried the mount<\/strong> command, but that does not work with file globbing.<\/p>\n","protected":false},"excerpt":{"rendered":"
