ber_put_set - Linux


## Overview

ber_put_set is a command-line utility for managing sets of strings. It is primarily used to add, remove, and test membership in a set.

## Syntax

ber_put_set <name> <item>...
ber_unset_set <name> <item>...
ber_test_set <name> <item>...

## Options/Flags

  • -a: Append the item(s) to the set if they do not already exist.
  • -r: Remove the item(s) from the set if they exist.
  • -t: Test if the item(s) exist(s) in the set.

## Examples

Add items to a set:

ber_put_set colors red green blue

Remove items from a set:

ber_unset_set colors green

Test for membership:

ber_test_set colors blue

## Common Issues

  • The set does not exist: Create the set using ber_put_set before trying to add or remove items.
  • The item already exists in the set: Use the -a option to append the item to the set only if it does not already exist.

## Integration

ber_put_set can be integrated with other Linux commands using pipes or shell functions. For example, to add the output of ls to a set:

ls | xargs ber_put_set files
