I can't find a shell command to remove all the FIFO files inside a directory. In fact, for the removal of directories, the rm command offers the options -d, --dir, but for FIFOs it offers no option.For now, the only workaround found is to call the FIFO like foo.fifo so that it is easy to remove them with rm *.fifo.
How to remove all FIFO files with a shell command
