Get a list of Mageia Linux mirrors providing rsync connectivity for Mageia 4 release
Need to find a Mageia Linux mirror server providing Mageia 4 via rsync? Modify the "url=" string for the version you want. This shows i586 which is the 32bit version. If you want the 64bit version it is: url=http://mirrors.mageia.org/api/mageia.4.x86_64.list; wget -q ${url} -O - | grep rsync:

find all writable (by user) files in a directory tree (use 4 for readable, 1 for executable)

Instead of writing a multiline if/then/else/fi construct you can do that by one line
instead of writing: if [[ "$1" == "$2" ]]; then echo "$1 is equal $2" else echo "$1 differs from $2" fi do write: [[ "$1" == "$2" ]] && echo "$1 is equal $2" || echo "$1 differs from $2"

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"
