# opasorthosts(8)

## NAME

opasorthosts

Sorts its standard input in a typical host name order and sorts to standard output. Hosts are sorted alphabetically (case-insensitively) by any alpha-numeric prefix, and then sorted numerically by any numeric suffix. Host names may end in a numeric field which may optionally have leading zeros. Unlike a pure alphabetic sort, this command results in intuitive sequencing of host names such as: host1, host2, host10.

This command does not remove duplicates; any duplicates are listed in adjacent lines.

Use this command to build mpi\_hosts input files for applications or cable tests that place hosts in order by name.
