Returns the N most recently modified files from anywhere 'below' (and including) the current working directory, in order, with details.

Returns a list, with attributes (think `ls -l`), in reverse chronological order. N is a single numeric parameter. Robust against unfriendly filenames and directory structures. Show Sample Output

nmf() { find . -type f -printf '%T@ ' -print0 -printf '\n' | sort -rn | head -"$1" | cut -f2- -d" " | tr -d "\0" | tr "\n" "\0" | xargs -0 ls -Ulh; }

displays an uncluttered list of the names of all variables and functions in the current environment, (without shell functions and definitions)

Normally executing 'set' returns a vast amount of information, including the source code of every function and variable within the environment - including those that are part of the shell. By using the -o posix argument, bash runs temporarily in POSIX mode for this command, which simplifies expressions and leaves out the shell's own functions and definitions - leaving a much smaller, more useful list.
