man pathmerge (Administration système) - merge sorted paths files
NAME
pathmerge - merge sorted paths files
SYNOPSIS
/usr/lib/smail/pathmerge file ...
DESCRIPTION
Pathmerge takes a set of sorted path files, as produced by pathalias(8), and generates on the standard output a merge of the path information, with one path given for each hostname. Precedence for paths goes to the files given earlier in the argument list. One of the filenames given in the argument list can be - to specify the standard input.
As an example of the use of pathmerge, let's say that we have two files, forces and paths, whose contents are, respectively:
ihnp4 cbosgd!ihnp4!%s muts12 muts12!%s sun sun!%sand
cbosgd cbosgd!%s ihnp4 ihnp4!%s sun ames!sun!%s uunet uunet!%s
The command ``pathmerge forces paths'' will produce on the standard output:
cbosgd cbosgd!%s ihnp4 cbosgd!ihnp4!%s muts12 muts12!%s sun sun!%s uunet uunet!%sFor the purposes of pathmerge, a hostname is terminated by either a space, a tab, a colon or a newline. The number of file arguments is limited by the number of available file descriptors, as all of the files are opened and read simultaneously.
