TACHK(1)

💅 tachk — the trust anchor check, bestie edition

okay so tachk is a lil script living in the User Contributed Perl Documentation corner of your manual, and she has ONE job: vibe-check the trust anchors in a named.conf file. let's get into it 🎀

---

✨ NAME ✨

tachk — check the validity of the trust anchors in a named.conf file 🦋

---

🌸 SYNOPSIS 🌸

tachk [options] <named.conf>

---

💖 DESCRIPTION 💖

so basically, tachk checks the validity of the trust anchors in the named.conf file you point her at. what you actually see coming back depends on which options you picked — she's flexible like that 💅

⚠️ heads up bestie: this script may be removed in future releases. not me getting attached to a deprecated icon 😭

---

👑 OPTIONS 👑

tachk takes two flavours of options: record-attribute options and output-style options. both sets are broken down below, so don't skip ahead 🫶

🍓 Record-Attribute Options

these ones decide which trust anchor records get shown. the vibe check of what's even on the menu ✨

• -valid — shows you the valid trust anchors in a named.conf file. the good ones. the ones that ate 💅
• -invalid — shows you the invalid trust anchors in a named.conf file. the ones that did not eat 😭

🌈 Output-Format Options

these ones decide how the trust anchor info gets displayed. and listen: if you don't pass any of them, you get the zone name and the key tag for each trust anchor. that's the default, periodt 💜

• -count — shows you the count of matching records, but not the matching records themselves. the receipts without the drama ✨
• -long — gives you the long form of output. the zone name and key tag get displayed for each trust anchor 📏
• -terse — displays only the name of the zones selected by the other options. short, sweet, iconic 🎀
• -Version — displays the version information for tachk and the DNSSEC-Tools package 👑
• -help — display a usage message. your girl always comes through 🫶
