Utils.sh

utils.sh (opens new window) is a collection of functions to make scripting in bash easier.

You can place uc_ variables in the head of your script to configure utils functions for your liking.

uc_ variable	function	description
uc_ifc_posfix	ifcontinue	Change default posfix ([yes/no]).
uc_gr_len	gen_random	Change default length (12).
uc_rn_err_msg	run	Change the structure of the error msg.
uc_rn_inf_msg	run	Change the structure of the info msg.

Each function description includes its uc_ variables with examples.

If a uc_ variable has dynamically changing parts, you'd have to use placeholders, placeholders are called using {[ name ]}:

placeholder	function	description
{[ rn_cmd ]}	run	The command executed by the run function.
{[ rn_err ]}	run	The error returned after executing a given command with run.
