delete PBS jobs based on strings from qstat output

Clear terminal Screen

Find last modified files in a directory and its subdirectories
Goes through all files in the directory specified, uses `stat` to print out last modification time, then sorts numerically in reverse, then uses cut to remove the modified epoch timestamp and finally head to only output the last 10 modified files. Note that on a Mac `stat` won't work like this, you'll need to use either: $ find . -type f -print0 | xargs -0 stat -f '%m%t%Sm %12z %N' | sort -nr | cut -f2- | head or alternatively do a `brew install coreutils` and then replace `stat` with `gstat` in the original command.

list unique file extensions recursively for a path, include extension frequency stats
Get the longest match of file extension (Ex. For 'foo.tar.gz', you get '.tar.gz' instead of '.gz')

Convert decimal numbers to binary
Convert some decimal numbers to binary numbers. You could also build a general base-converter: $ function convBase { echo "ibase=$1; obase=$2; $3" | bc; } then you could write $ function decToBun { convBase 10 2 $1; }

Kill processes that have been running for more than a week

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

ls only directories
Like normal ls, but only lists directories. Can be used with -l to get more details (ls -lad */)

Remove a range of lines from a file
Deletes lines to of a file. You must put the end line first in the range for the curly brace expansion, otherwise it will not work properly.

Remove all zero size files from current directory (not recursive)
