Built for EDA text edits

Every command, every example is anchored in a real RTL/DV task — filelist rewrites, +incdir migrations, +UVM_TESTNAME swaps, SDC corner renames, UVM log cleanup. No generic Linux-admin content.

Interview-ready depth

Tiered interview module plus per-chapter interview weighting — substitution semantics, capture groups, in-place safety, the sed-vs-awk-vs-grep boundary, and the text-transformation questions actually asked in DV / EDA-automation interviews.

Edit → refactor → ship

From the first s/// to a 5000-file RTL signal rename, a per-corner SDC migration, and a UVM-log normaliser — the full sed engineering loop every RTL, DV, and EDA-automation engineer eventually owns.
