NAME

pathmerge - merge sorted paths files

SYNOPSIS

X_UTIL_BIN_DIR_X/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!%s

and

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!%s

For 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.
