Otherwise, dir becomes the current directory for file and shell command references. The given shell command is executed. The specified flags are given as argu- ments to pathalias. A pathsort directive is assumed to follow the end of a configuration file if an execution block is not terminated prior to the end of file. A map , safemap , delete , adjust , dead or file directive starts a block.
Successive directives continue it.
A pathalias or path- sort directive ends a block. The end of a file can end a block, generating an implicit pathsort directive. The exception is when a end of block command is read when no block was started. In this case the block is ignored. Directives such as cd , sh or text within a block only effect that block.
