TACHK(1)

✨ NAME ✨

okay bestie, welcome to TACHK(1) — yes, from the User Contributed Perl Documentation — which is literally the manual for tachk. It checks the validity of the trust anchors in a named.conf file. trust-anchor vibe check, iconic behavior. 💅

🌸 SYNOPSIS 🌸

tachk [options] <named.conf>

🦋 DESCRIPTION 🦋

so here's the tea: tachk checks the validity of the trust anchors in the named.conf file you specify. The output given depends on the options selected — choose your own adventure, bestie.

⚠️ Note: this script may be removed in future releases. not to be dramatic, but 😭 keep that in mind.

🎀 OPTIONS 🎀

tachk takes two types of options: record-attribute options and output-style options. These option sets are detailed below. slay.

💖 Record-Attribute Options 💖

These options define which trust anchor records will be displayed.

• -valid — this option displays the valid trust anchors in a named.conf file. ✅
• -invalid — this option displays the invalid trust anchors in a named.conf file. ❌

🌈 Output-Format Options 🌈

These options define how the trust anchor information will be displayed. Without any of these options, the zone name and key tag will be displayed for each trust anchor. that's the default, no cap.

• -count — the count of matching records will be displayed, but the matching records will not be. just the number, not the receipts 💀
• -long — the long form of output will be given. The zone name and key tag will be displayed for each trust anchor.
• -terse — this option displays only the name of the zones selected by other options. short and sweet.
• -Version — displays the version information for tachk and the DNSSEC-Tools package.
• -help — display a usage message.
