Check These Out

Bulk renames with find, sed and a little escaping
This command is a more flexible than my previous submission. It will work with spaces however suuuuper hacky and ugly. Source: http://www.unix.com/shell-programming-scripting/146173-find-rename-files-using-find-mv-sed.html

list block devices
Shows all block devices in a tree with descruptions of what they are.

Transforms a file to all uppercase.

Check (partial) runtime-dependencies of Gentoo ebuilds
The output is only partial because runtime dependencies should count in also commands executed via system() and libraries loaded with dlopen(), but at least it gives an idea of what a package directly links to. Note: this is meaningful *only* if you're using -Wl,--as-needed in your LDFLAGS, otherwise it'll bring you a bunch of false positives.

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Show memory usage of all docker / lxc containers (works on CoreOS)

Convert unix timestamp to date
The "-d" option for gnu's "date" command can calculate positive or negative offset from any time, including "now". You can even specify a source timezone (the output timezone can be set with the TZ environment variable). Useful! Fun! Not very well documented!

Check RAM size
Check RAM size

Detect illegal access to kernel space, potentially useful for Meltdown detection
