Shell Library Design

Function Prefix

Name Helpers

A small prefix keeps library helper names grouped and reduces accidental collisions with script-level functions.

Program

Play the script to choose the prefix and see the generated helper-style name.

library_function_prefix.sh 
#!/usr/bin/env bash

lib_prefix=
helper="start"
function_name="${lib_prefix}_${helper}"
echo "$function_name"

#!/usr/bin/env bash

lib_prefix=
helper="start"
function_name="${lib_prefix}_${helper}"
echo "$function_name"
name prefix A prefix groups related helper names together.
collision avoidance Distinct helper names reduce clashes with caller scripts.
library convention A naming convention is part of the library's public contract.
