Five small Unix-style loop & format helpers, fully offline:
lib/each.sh
- replaces v1 `each`
- run a CMD per item: args, stdin lines, or {}-placeholder substitution
- example: tbn adt | awk '{print $2}' | each.sh 'route_test {}'
lib/each-site.sh
- replaces v1 each_site / each_site_hdr / each_site_tcl patterns
- iterates every site under $HCIROOT with HCISITE/HCISITEDIR auto-exported
- --filter REGEX limits which sites; --hdr prints a header before each
lib/len2nl.sh
- replaces v1 `len2nl`
- strict superset: handles length-prefixed (digits before MSH),
MLLP (\x0b...\x1c\x0d), and segment CRs (→ LF)
- works as stdin filter or with file arg
lib/csv-to-table.sh
- 2-column CSV → Cloverleaf .tbl format
- emits proper prologue (who, date, bidir, type, version)
- --has-header --default VALUE --bidir 0|1 --in-delim CHAR --user NAME --out PATH
lib/table-to-csv.sh
- reverse: .tbl → CSV
- --with-header --delim CHAR --include-meta
- confirmed clean round-trip: CSV → table → CSV byte-identical for the data rows
All 5 are pipeable, have --help, zero external deps beyond bash+awk+sed.

# each-site.sh — run a command for each site under $HCIROOT.
|
|
# Replaces v1 `each_site` / `each_site_hdr` / `each_site_tcl` patterns.
|
|
#
|
|
# Usage:
|
|
# each-site.sh [--hciroot DIR] [--hdr] [--filter REGEX] <CMD ...>
|
|
#
|
|
# The current site is exposed to CMD as the env vars HCISITE and HCISITEDIR.
|
|
# The literal token {} in CMD, if present, is replaced with the site name.
|
|
#
|
|
# Examples:
|
|
# each-site.sh 'lib/nc-find.sh --name adt --netconfigs "$HCISITEDIR/NetConfig"'
|
|
# each-site.sh --hdr 'echo "Hey from $HCISITE; netconfig=$HCISITEDIR/NetConfig"'
|
|
# each-site.sh --filter '^(ancout|epic)$' 'wc -l "$HCISITEDIR/NetConfig"'
|
|
# each-site.sh 'lib/nc-parse.sh list-protocols "$HCISITEDIR/NetConfig" | wc -l'
|
|
#
|
|
# --hdr prints a "===== <site> =====" header before each run.
