Here are additional examples of enabling verbose output across various tools and systems, expanding on the theme of providing more detailed feedback or logging:

PowerShell: To enable verbose output, use the -Verbose switch with cmdlets that support it. For example:
```
Get-Process -Verbose
```
Alternatively, set the $VerbosePreference variable globally:
```
$VerbosePreference = "Continue"
```
CMake: To get verbose output during the build process, use the --verbose flag or set VERBOSE=1:
```
cmake --build . --verbose
```
Or:
```
make VERBOSE=1
```
Make: To enable verbose output and see all commands executed, use the -d flag for debugging or avoid silencing output with @:
```
make -d
```
Or edit the Makefile to remove @ prefixes from commands.
GCC (GNU Compiler Collection): For verbose compilation output, use the -v flag:
```
gcc -v -o output source.c
```
GDB (GNU Debugger): To increase verbosity, use the set verbose on command within GDB:
```
(gdb) set verbose on
(gdb) run
```
Ruby: Run Ruby scripts with verbose mode using the -v or --verbose flag:
```
ruby -v script.rb
```
For additional warnings, use -w:
```
ruby -w script.rb
```
Perl: Enable verbose output with the -v flag or use the diagnostics pragma for detailed error messages:
```
perl -v script.pl
```
Or in the script:
```
use diagnostics;
```
PHP: Run PHP scripts with verbose error reporting by setting error_reporting and display_errors in php.ini:
```
error_reporting = E_ALL
display_errors = On
```
Or from the command line:
```
php -d error_reporting=E_ALL script.php
```
R: To enable verbose output in R scripts, use the verbose=TRUE argument in functions that support it (e.g., install.packages):
```
install.packages("dplyr", verbose=TRUE)
```
Go (Golang): For verbose output during compilation or testing, use the -v flag:
```
go build -v
go test -v
```
Rust (Cargo): Enable verbose output with Cargo using the -v or -vv flags:
```
cargo build -v
cargo run -vv
```
Jenkins: To enable verbose logging for a pipeline, add the verbose option in the script or configure the console output in the job settings. For example, in a Jenkinsfile:
```
sh 'some_command --verbose'
```
Alternatively, set the system property -Dhudson.model.TaskListener.verbose=true when starting Jenkins.
Vagrant: Get verbose output with the --debug flag:
```
vagrant up --debug
```
Puppet: Run Puppet with increased verbosity using the --verbose or --debug flags:
```
puppet apply site.pp --verbose
puppet apply site.pp --debug
```
Chef: Enable verbose output with the -l (log level) flag:
```
chef-client -l debug
```
SaltStack: Increase verbosity with the -l flag (e.g., debug or trace):
```
salt '*' test.ping -l debug
```
PostgreSQL (psql): To get verbose output from psql, use the -e flag to echo queries or \set VERBOSITY verbose for detailed error messages:
```
psql -e -f script.sql
```
Or in psql:
```
\set VERBOSITY verbose
```
MySQL: Run the MySQL client with verbose output using --verbose:
```
mysql --verbose < script.sql
```

SQLite: Use the .explain command for verbose query execution plans:

sqlite3 database.db
sqlite> .explain
sqlite> SELECT * FROM table;

MongoDB: Enable verbose logging by starting mongod with the -v flag (up to -vvvvv for more detail):
```
mongod -v
```
Elasticsearch: Start Elasticsearch with verbose logging by adjusting the log4j2.properties file:
```
logger.action.level = debug
```
Or pass --verbose when starting:
```
elasticsearch --verbose
```
NGINX: Test configuration with verbose output using -T:
```
nginx -T
```
For runtime verbosity, increase the error_log level in nginx.conf:
```
error_log /var/log/nginx/error.log debug;
```
Apache HTTP Server: Enable verbose logging by setting the LogLevel directive in httpd.conf or apache2.conf:
```
LogLevel debug
```
OpenSSL: Get verbose output with commands like s_client:
```
openssl s_client -connect example.com:443 -debug
```
JUnit (Java Testing): Run JUnit tests with verbose output by configuring the test runner (e.g., Maven Surefire plugin):
```
<configuration>
    <argLine>-verbose</argLine>
</configuration>
```

These examples cover a wide range of tools across programming languages, build systems, databases, servers, and DevOps utilities. Let me know if you’d like more specific examples or details for any particular tool!
