Check These Out

To create files with specific permission:

take a look to command before action

add |sh when you agree the list, I often use that method to prevent typos in dangerous or long operations

list all hd partitions

Only one command and not dependant on full read access to the devices.

list the top 15 folders by decreasing size in MB

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"

lists files and folders in a folder

lists files and folders in a folder with summary.

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 directories in the PATH, one per line

The output of "echo $PATH" is hard to read, this is much easier. The parentheses ensure that the change to the input field separator (IFS) only happens the the sub shell and not affecting the current shell.

Programmatic way to find and set your timezone

create a progress bar...

A simple way yo do a progress bar like wget.
