Find and Replace

• To Find Files:
  • {sh} grep -RilZP pat dir ; OR
    • R — recursive, follow symlinks (r to not follow)
    • i — case insensitive
    • l — print file names, not matches
    • Z — Use NUL to separate output not \n
      • By default, other commands separate on all whitespace (spaces and newlines), include spaces in paths. If we use NUL across all commands, we can avoid this
    • P — Use Perl Regexp (use whatever pat matching syntax is preferred)
  • {sh} rg -l0 pat dir
    • l — print file names, not matches
    • 0 — NUL separated
    • Uses rust ERE (no lookarounds, back references) by default; enable full perl regexp with P
• To replace:
  • {sh} rg -l0 regexp dir | xargs -0 sed 's/find-pat/replace-with-pat/g'
    • xargs
      • -0 — NUL separated
    • sed
      • ssubstituteg` globally
      • Access ERE-style regrexp with -E
