| Info on that horrible operating system that's a million times better than Micro$oft Windoze. Why do I say it's horrible? Mostly because I don't spend enough time there to know how to do things and figuring it out is often a PITA. | Info on that horrible operating system that's a million times better than Micro$oft Windoze.

| + | ===== Commifying a number in Linux ===== | ||
| + | < | ||
| + | grep MemTotal / | ||
| + | </ | ||
| + | Bonus: That particular command tells you how much memory is installed. I think. | ||
| + | ----------------------- | ||
| + | ===== Pad IPs to Make Them Sortable ===== | ||
| + | < | ||
| + | echo 172.16.16.112/ | ||
| + | 172.016.016.112/ | ||
| + | </ | ||
| + | ----------------------- | ||
| + | ===== Date ===== | ||
| + | My preferred date/time format is ISO 8601. | ||
| + | < | ||
| + | Can also be accomplished with... | ||
| + | < | ||
| + | Specific timezone and 3 hours in the future... | ||
| + | < | ||
| + | ----------------------- | ||
| + | ===== Find ===== | ||
| + | I never remember how to find old files... either of these will work. The second one uses minutes (I don't know why you'd want to) and shows how to exclude files. | ||
| + | find DIR -name " | ||
| + | find . ! -name ' | ||
| + | |||
| + | Add this to the end and anything that matches will be deleted. | ||
| + | < | ||
| + | -exec rm -f {} \; | ||
| + | </ | ||
| + | |||
| + | Limit depth to current directory. | ||
| + | < | ||
| + | find . -maxdepth 1 -name " | ||
| + | </ | ||
| + | |||
| + | # to delete empty dirs | ||
| + | < | ||
| + | find -type d -empty -delete | ||
| + | </ | ||
| + | # to delete files over some age & empty dirs | ||
| + | < | ||
| + | find /some/path -depth \( \( -type f -daystart -mtime +100 \) -o -type d -empty \) -ls | ||
| + | </ | ||
| + | |||
| + | ----------------------- | ||
| + | ===== Find the Fat Folder ===== | ||
| + | Useful for finding which directory is sucking up all your disk space. | ||
| + | < | ||
| + | du -h --max-depth=1 | sort -hr | ||
| + | </ | ||
