sleep for a random amount of time up to an hour

This command is good for a cron job or where you may have a lot of jobs potentially coincide on a scarce resource (like writing files back to a file server all at once). This will insert a sleep of a random amount of time up to an hour.

Schedule one job after another (running).

Run one script after another in such a way that second script starts after finishing first one. Without using Pipe | or ampercent && i.e. the first process is already running and you want second one to start after the first one finishes. And this can be done in different folder in case the output of second script will affect the output of first script. So run this on any folder you wish to. Where $PID is the process id of the already running job (add PID number) script2 is your script you wish to run after first script ends sleep 1 is sleep for one second (SUFFIX may be ?s? for seconds (the default), ?m? for minutes, ?h? for hours or ?d? for days, read man sleep) Show Sample Output

Generate a one-time TOTP token, then restore the clipboard after 3 seconds

Typing a word in terminal is easier than digging your phone out, opening your two-factor authentication app and typing the code in manually. This alias copies the one-time code to your clipboard for 3 seconds (long enough to paste it into a web form), then restores whatever was on the clipboard beforehand. This command works on Mac. Replace pbpaste/pbcopy with your distribution's versions.

Simple Bashrc Cron Job Using Aliases For A Simple Interface

Everytime You Run Bash It Will Run And Send The Command To Background In A Loop Forever. This Is Useful In Android To Avoid Getting Discconnected While Using ADB Or Other Services Like SSH By Being Inactive For Long Periods Of Time.

determine if a shared library is compiled as 32bit or 64bit

Determines the flavor of a shared library by looking at the addresses of its exposed functions and seeing if they are 16 bytes or 8 bytes long. The command is written so the library you are querying is passed to a variable up font -- it would be simple to convert this to a bash function or script using this format.
