FILTER-COLUMNS(1)

✨ NAME ✨

filter-columns — filter a tab-delimited table per custom criteria 💅

so like, it's a little table-filtering icon, and it lives in the NCBI Entrez Direct User's Manual bestie. page filter-columns(1). iykyk 💖

🦋 SYNOPSIS 🦋

filter-columns expr

---

🌸 DESCRIPTION 🌸

okay so here's the vibe: filter-columns reads a tab-delimited table from standard input and writes to standard output literally all the rows that match the awk(1) expression you handed it as expr. that's it. that's the whole job. and it ate. 👑

so the flow is giving: table goes in 🫶, matching rows come out, no cap.

---

🎀 NOTE 🎀

bestie pls. callers will typically want to surround expr with single quotes to protect it from shell expansion. the shell is nosy and will absolutely try to touch your expression if you let it. wrap it in ' ' and breathe. 😭✨
