💖 opasorthosts — the glow-up your host list deserves 💖

okay so bestie, let me put you onto opasorthosts from the IFSFFCLIRG manual (section 8, we love a sysadmin era 👑).

This little icon sorts its standard input into a typical host name order and drops the result on standard output. Here's the tea: hosts get sorted alphabetically (case-insensitively, no cap) by whatever alpha-numeric prefix they've got, and then sorted numerically by any numeric suffix. Host names may end in a numeric field, and that field may optionally have leading zeros. So unlike a plain alphabetic sort (which is lowkey a mess 💀), this command gives you the intuitive sequencing of host names like: host1, host2, host10.

Heads up bestie: this command does NOT remove duplicates. Any duplicates are listed in adjacent lines. It's giving "i said what i said" 🙈.

Use it to build mpi_hosts input files for applications or cable tests that place hosts in order by name. Main character energy fr fr. ✨

✨ Syntax ✨

opasorthosts < hostlist>  output_file

🎀 Options 🎀

• --help — produces the full help text. literally the full thing, no crumbs.
• hostlist — specifies the list of host names. yes queen, this is the input.
• output_file — specifies the sorted list output. the glow-up destination 🦋
