How to use glob qualifiers in Zsh

Zsh glob qualifiers narrow a pathname match before the command sees it. They help when a broad pattern such as *.log would include files with the wrong type or permission state, especially before cleanup or permission commands.

A qualifier sits in parentheses at the end of the pattern. (.) keeps plain files, (/) keeps directories, and (*) keeps executable plain files. Qualifiers are part of the glob, so reports/*.log(.) returns plain log files and leaves non-log files out of expansion.

The example below builds a temporary tree under /tmp/zsh-glob-demo and previews each match with print -rl --. That output is the safety check to read before reusing the same pattern with rm, chmod, or another command that changes paths.

Steps to use glob qualifiers in Zsh:

Create a safe workspace with separate report and archive directories.
```
$ mkdir -p /tmp/zsh-glob-demo/reports /tmp/zsh-glob-demo/archive
```
Enter the workspace before testing relative patterns.
```
$ cd /tmp/zsh-glob-demo
```
Create the first log file.
```
$ printf 'one\n' > reports/app.log
```
Create the second log file.
```
$ printf 'two\n' > reports/db.log
```
Create a non-log file beside the log files.
```
$ printf 'note\n' > reports/readme.txt
```
Mark one log file executable.
```
$ chmod u+x reports/db.log
```
List only plain log files.
```
$ print -rl -- reports/*.log(.)
reports/app.log
reports/db.log
```
The (.) qualifier keeps the match to plain files.
List only directories in the current location.
```
$ print -rl -- *(/)
archive
reports
```
The (/) qualifier matches directories, so files under reports/ are not returned by this pattern.
List executable plain files under the reports/ directory with the (*) qualifier.
```
$ print -rl -- reports/*(*)
reports/db.log
```
Globs are expanded before the command runs. Preview new qualifiers with print -rl -- PATTERN before passing the same pattern to rm, chmod, or another command that changes files.
Leave the test workspace.
```
$ cd /tmp
```
Remove the temporary workspace.
```
$ rm -rf /tmp/zsh-glob-demo
```
