# Using bash’s shopt builtin to manage Linux shell behavior
# The shopt builtin offers 53 settings that can alter how bash behaves. 
# Read this post and then refer to bash's man page to follow up on how these settings might work for you.
# https://www.gnu.org/software/bash/manual/html_node/The-Shopt-Builtin.html
# https://www.networkworld.com/article/3574960/using-bashs-shopt-builtin-to-manage-linux-shell-behavior.html

#set -x # Debug trace
#The set -o pipefail option is used in Bash to handle pipeline failures (chaining commands using the "|" operator) more accurately. Typically, 
#a pipeline returns the exit code of the last command executed in the pipeline. However, if an intermediate command fails, 
#theexit code is usually ignored and the pipeline is considered successful.
#Enabling set -o pipefail changes the default behavior. In this mode, the pipeline will return the exit code of the last command that failed 
#within the pipeline, instead of returning the exit code of the last executed command. This can be useful for detecting failuresin complex pipelines, 
#especially when dealing with data processing or task automation.
#set -o pipefail # Will cause the pipeline to return the exit code of the last failed command within the pipeline.
#set -e # Debug (Errors: exit) mode 'exit-on-error' or 'errexit'. Terminates execution immediately if any command returns a non-zero error code.
#set -u # Enables 'nounset' or 'unbound variables' mode. Generates an error if an uninitialized variable is referenced.
#set -f # Disable globstar. Disables wildcard expansion (globbing).
#set -efu
#set -eo pipefail

# shopt | column
#
## By enabling the globstar option, you can glob all matching files in this directory and all subdirectories:
## Example: for i in **/*.sh; do echo ${i}; done
## For allowing the Bash shell to expand globes (wildcards) across all matching files in directories and subdirectories
#########################################################################################################################
## Habilita a opção globstar, permitindo que o shell Bash expanda globos (wildcards) em todos os arquivos correspondentes 
## nos diretórios e subdiretórios.
shopt -s globstar

## If set, the extended pattern matching features described above (see Pattern Matching) are enabled.
###################################################################################################
## Habilita a opção extglob, que permite o uso de recursos avançados de correspondência de padrões, 
## como padrões de correspondência estendidos.
shopt -s extglob

## If set, minor errors in the spelling of a directory component in a cd command will be corrected. 
## The errors checked for are transposed characters, a missing character, and a character too many. 
## If a correction is found, the corrected path is printed, and the command proceeds. This option is only used by interactive shells.
#########################################################################################################################
## Habilita a opção cdspell, que corrige erros menores na digitação de nomes de diretórios ao usar o comando cd. 
## Por exemplo, se você digitar um diretório com caracteres transpostos, ausentes ou extras, o Bash tentará corrigi-lo 
## e executar o comando cd para o diretório corrigido.
shopt -s cdspell

## If set, Bash replaces directory names with the results of word expansion when performing filename completion.
## This changes the contents of the Readline editing buffer. If not set, Bash attempts to preserve what the user typed.
#########################################################################################################################
## Habilita a opção direxpand, que substitui nomes de diretórios pelos resultados da expansão de palavras durante 
## a conclusão de nomes de arquivos. Isso significa que, ao usar a conclusão de tabulação, o Bash substituirá nomes 
## de diretórios pelos caminhos completos correspondentes.
shopt -s direxpand

## If set, Bash attempts spelling correction on directory names during word completion if the directory name initially supplied does not exist.
##############################################################################################################################################
## Habilita a opção dirspell, que realiza correção ortográfica em nomes de diretórios durante a conclusão de tabulação, caso o nome do diretório 
## fornecido inicialmente não exista. O Bash tentará corrigir o nome do diretório e completá-lo corretamente.
shopt -s dirspell

## If set, a command name that is the name of a directory is executed as if it were the argument to the cd command. 
## This option is only used by interactive shells.
###################################################################################################################
## Habilita a opção autocd, permitindo que um nome de comando que corresponda a um diretório seja executado como se fosse o argumento 
## para o comando cd. Isso é útil para navegar diretamente para um diretório digitando seu nome no prompt de comando, em vez de precisar digitar 
## explicitamente o comando cd.
shopt -s autocd

## With this option enabled, matching wildcards will not be case sensitive. For example, *.txt will match files with a .txt extension, 
## regardless of case.
######################################################################################################################################
## Com essa opção habilitada, a correspondência de globos (wildcards) não será sensível a maiúsculas e minúsculas. Por exemplo, *.txt
## corresponderá a arquivos com extensão .txt, independentemente do uso de letras maiúsculas ou minúsculas.
shopt -s nocaseglob

# Enable history reediting and verification.
shopt -s histreedit

## This option causes the history to be displayed before each command is executed. After displaying the command history, 
## you have the option to edit or confirm the execution. This can help to avoid errors when running old commands from history.
######################################################################################################################################
## Essa opção faz com que o histórico seja exibido antes da execução de cada comando. Após exibir o comando do histórico, você tem a opção 
## de editar ou confirmar a execução. Isso pode ajudar a evitar erros ao executar comandos antigos do histórico.
shopt -s histverify 

## With this option enabled, the history will be stored in single-line format instead of the default multi-line format. This makes it easy 
## to search and manipulate history using tools like grep or scripts.
######################################################################################################################################
## Com essa opção ativada, o histórico será armazenado no formato de linha única, em vez do formato de várias linhas padrão. 
## Isso facilita a pesquisa e manipulação do histórico usando ferramentas como grep ou scripts.
#shopt -s lithist

## By enabling this option, the history will not store duplicate consecutive commands. This can help reduce the history size and preventrepeated 
## commands from taking up unnecessary space.
######################################################################################################################################
## Habilitando essa opção, o histórico não armazenará comandos consecutivos duplicados. 
## Isso pode ajudar a reduzir o tamanho do histórico e evitar que comandos repetidos ocupem espaço desnecessário.
shopt -s cmdhist

## With this option enabled, Bash will not complete empty commands when pressing the Tab key twice. This prevents Bash from listing 
## all available commands when no commands have been entered.
######################################################################################################################################
## Com essa opção ativada, o Bash não completará comandos vazios ao pressionar a tecla Tab duas vezes. 
## Isso evita que o Bash liste todos os comandos disponíveis quando nenhum comando foi digitado
shopt -s no_empty_cmd_completion
