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
