Description

The linux-pipes command runs find / -type p to search the entire filesystem for named pipe (FIFO) files. For each pipe file found, it reads the file attributes and collects the path, size, timestamps, and permission information.

The permissions field prepends a p character to indicate a pipe, in addition to the standard permission string. For example, a pipe file where the owner has read and write permissions is returned as prw-------.

When a query cancellation is requested, the pipe file search is stopped immediately.

Examples

Query all pipe files
```
linux-pipes
```
Queries all named pipe files on the system.
Filter pipe files in a specific directory
```
linux-pipes
| search file_path == "/tmp/*"
```
Filters only pipe files under the /tmp directory.
Query pipe files with write permission for others
```
linux-pipes
| search others_write == true
```
Queries pipe files where others have write permission.
