Code:
#!/bin/sh
pserver=""
while read server path
do
  if [ "$server" != "$pserver" ]; then
    exec 3>>"$server".out
    pserver=$server
  fi
  echo "$server $path" >&3
done < datafile.txt

If the input file is sorted, it can become more efficient
Code:
#!/bin/sh
pserver=""
sort -k1,1 datafile.txt |
while read server path
do
  if [ "$server" != "$pserver" ]; then
    exec 3>"$server".out
    pserver=$server
  fi
  echo "$server $path" >&3
done < datafile.txt

fc-match

FC-MATCH(1)                                                                                                                            FC-MATCH(1)

NAME

       fc-match - match available fonts

SYNOPSIS

       fc-match [ -asvVh ] [ --all ] [ --sort ] [ --verbose ] [ -f format | --format format ] [ --version ] [ --help ]
           [ pattern  [ element ... ]  ]

DESCRIPTION

       fc-match  matches pattern (empty pattern by default) using the normal fontconfig matching rules to find the best font available.  If --sort
       is given, the sorted list of best matching fonts is displayed.  The --all option works like --sort except that no pruning is  done  on  the
       list of fonts.

       If  any elements are specified, only those are printed.  Otherwise short file name, family, and style are printed, unless verbose output is
       requested.

OPTIONS

       This program follows the usual GNU command line syntax, with long options starting with two dashes (`-').  A summary of options is included
       below.

       -a --all
              Displays sorted list of best matching fonts, but do not do any pruning on the list.

       -s --sort
              Displays sorted list of best matching fonts.

       -v --verbose
              Print verbose output of the whole font pattern for each match, or elements if any is provided.

       -f --format format
              Format output according to the format specifier format.

       -V --version
              Show version of the program and exit.

       -h --help
              Show summary of options.

       pattern
              Displays fonts matching pattern (uses empty pattern by default).

       element
              If set, the element property is displayed for matching fonts.
