WinuxCmd
Use this skill when working inside the WinuxCmd repository or when preparing a
WinuxCmd release bundle.
Start Here
If you are already in the repo, activate the workspace-local command
directory for the current shell:
.\scripts\activate-workspace.ps1
If you are in cmd, use:
scripts\activate-workspace.cmd
If you are starting from a downloaded WinuxCmd release, register the release
binary in the workspace first:
When you need command help on Windows, call man.exe, not man.
Why man.exe
PowerShell resolves aliases before native executables.
man is often an alias for PowerShell help, so man.exe is the unambiguous
WinuxCmd command.
Use explicit .exe names whenever an alias could collide with a WinuxCmd
tool.
Workspace Activation
.winuxcmd/bin is the repo-local command directory.
scripts/setup-workspace-bin.ps1 creates the command links there.
scripts/activate-workspace.ps1 prepends .winuxcmd/bin to the current
PowerShell session only and clears common alias collisions for that session.
scripts/activate-workspace.cmd does the same for CMD sessions.
scripts/install-workspace-profile-hook.ps1 adds a per-user PowerShell 7 /
Windows PowerShell 5.1 hook so new shells auto-activate in this repository.
If you are already inside an extracted release directory, scripts/create_links.ps1
can generate the release-side command links there.
Typical commands after activation:
man.exe ls
grep.exe -n TODO README.md
winuxcmd.exe help sort
Rules
Do not modify user PATH or machine PATH.
Do not rely on PowerShell aliases such as man or ls.
Use the repository-local .winuxcmd\bin directory for command execution.
If a command exists both as a PowerShell alias and as a WinuxCmd executable,
always call the executable with .exe.
Build and Test
Use scripts/build-with-vs.ps1 when you need an MSVC build/test run.
Default target: winuxcmd-tests.
Default build directory: build-vs.
Default environment script: vcvars64.bat.
Command Guidance
After activation, bare ls, cp, mv, rm, and similar common commands
should resolve to WinuxCmd in the current session.
Use the repo's GNU-parity flags when they reduce AI mistakes:
ls: -d, -b, -f, -I, -U, -X, -v, -i, -s, -h/--human-readable, --block-size=SIZE, -Q, -b, -q, -N, --quoting-style=WORD; directory long listings include total, hard-link counts come from Windows file metadata, -h humanizes long sizes and -s/total, sort/time/quoting-affecting options use last-occurrence precedence, and wildcard matches that are directories list contents unless -d is active
cp: -a/--archive, -p, -t, -T, -n, -u, -b/--backup, -S/--suffix; -t requires an existing directory, -t and -T conflict, self-copy is refused except --force --backup, and plain file copies do not create missing parents
mv: -t, -T, -n, -u, -b; -t requires an existing directory, -t and -T conflict, and ordinary multi-source moves require an existing target directory after wildcard expansion
rm: -f, -d/--dir, -r/-R/--recursive, -I, -i, --interactive[=never|once|always], --one-file-system; rm -f with no operands succeeds, removes only empty directories, and /// use last-option precedence for prompting/force behavior
Release Packaging
When packaging the skill, load references/release-packaging.md first.
Confirm the bundle layout, then package the standalone bundle with the
Windows binaries.
Keep the skill bundle rooted at winuxcmd/ with SKILL.md at the top level
of the archive.
Keep the skill bundle small and release-ready; long-form details belong in
references/.
install: -D, -d, -t, -T; -t and -T conflict, multi-source installs require an existing target directory after wildcard expansion, -D -t creates the target directory, and -d creates parent directories
sort: repeatable -k/--key with F[.C][OPTS][,F[.C][OPTS]], --sort=WORD, -M, -R, --random-source, -S/--buffer-size, -s, -t \0, -u, -V; -t \0 uses NUL as the field separator, global ordering modes use last-occurrence precedence, -n does not accept leading + or exponent notation, -h compares sign then SI suffix then value, -u uses sort-key equality and disables last-resort whole-line ordering, -c/-C -u rejects adjacent equal keys, -b affects -k F.C character counts, and end position .0 means field end
grep: -E, -F, -G, repeatable -e/--regexp, repeatable -f/--file, -i, -v, -n, -c, -l, -L, -H/-h, --label, --line-buffered, repeatable --include/--exclude/--exclude-from/--exclude-dir, -A/-B/-C context output, -o, -D/--devices, --color[=WHEN]; bare --color defaults to auto, invalid color modes fail, zero-byte -f pattern files match nothing, include/exclude file rules keep command-line order and the last matching rule wins, command-line file operands match include/exclude globs by name suffix, --exclude-dir skips matching command-line directories and ignores trailing slashes, context ranges merge, match prefixes use :, context prefixes use -, -o warns while ignoring context options, and wildcard operands that expand to directories recurse when -r/-R is active
sed: ordered repeatable -e/--expression and -f/--file, -i[SUFFIX] / --in-place[=SUFFIX], -n/--quiet/--silent, -E, -r, -s, -z/--null-data/--zero-terminated, -u/--unbuffered, -b/--binary; in-place editing creates no backup when suffix is omitted, appends suffix when it has no *, and replaces each * with the current filename otherwise; s/// supports &, \1-\9, numeric occurrence flags, g, p, and I/i; address negation with !, first~step, 0~step, and /regex/I are supported
head: -c, -n, -q, -v, -z; GNU count suffixes are accepted (KB/MB/.../QB decimal, K/M/.../Q binary, and KiB/.../QiB IEC) with overflow rejected; first-argument obsolete -[num][bkm][cqv] is accepted for compatibility, but prefer -c NUM or -n NUM
tail: -c, -n, -q, -v, -z, -f, -F, -s, --max-unchanged-stats, repeatable --pid, --debug, --retry; GNU count suffixes are accepted (KB/MB/.../QB decimal, K/M/.../Q binary, and KiB/.../QiB IEC) with overflow rejected; obsolete -[num][bcl][f] is accepted when it does not conflict with normal parsing, but prefer -c NUM, -n NUM, and -f
find: -L, -H, -name, -iname, -path, -ipath, -regex, -iregex, -type, -size, -empty, -mtime, -mmin, -newer, -mindepth, -maxdepth, -depth, -true, -false, !, -not, implicit AND, -a/-and, -o/-or, comma expressions, parentheses, -print, -print0, -printf (%p, %f, %h, %d, %y, %s, %m, %T@, %%), -delete, -prune, -quit, -exec ... {} ;, -exec ... {} +, -ok ... {} ;, -ok ... {} +; predicate operators and these common actions follow GNU expression precedence and short-circuit behavior; -H follows only command-line symlink roots unless -L is active; remaining gaps are full -printf, full GNU regex dialect details, and -delete plus -prune interaction edge cases
du: -a, -A/--apparent-size, -B/--block-size, -b/--bytes, -c/--total, -d/--max-depth, -h, --si, -H/--dereference-args, -k, -m, -0/--null, -S/--separate-dirs, -s, -t/--threshold, --time[=WORD], --exclude=PATTERN, -X/--exclude-from, --files0-from; default output uses 1024-byte blocks, later size-display options override earlier ones, --block-size=human-readable|si is accepted, --max-depth=0 prints only the root total, --time=atime|access|use|ctime|status|mtime uses last-occurrence precedence, ctime/status currently map to creation time on Windows, --exclude patterns stay literal option patterns, Windows size reporting uses file length as the allocated/apparent-size approximation, and -H is not SI output
printenv: -0/--null; named empty variables still emit empty records, mixed found/missing names preserve found output while returning status 1, and full enumeration skips Windows hidden =... pseudo-entries
tty: -s/--silent, --quiet; extra operands keep GNU-style stderr diagnostics with exit 2, non-tty stdin returns 1, and broken stdout during non-silent output returns GNU/uutils-style exit 3
pwd: -L/--logical, -P/--physical; default output remains physical, -L prefers an absolute PWD environment value when present, and the -L/-P family uses last-occurrence precedence
realpath: -e, -E, -m, -q, -s, -z, --relative-to, --relative-base; at least one path operand is required, canonicalization-mode options use last-occurrence precedence, empty path / relative-option operands are rejected as invalid empty strings, and under -e the relative-option operands must resolve to directories
readlink: -f, -e, -m, -n, -q, -s, -v, -z; canonical modes normalize Windows paths, default diagnostics stay quiet, and the -q/-s/-v family uses last-occurrence precedence
xargs: -n/--max-args, -L/--max-lines, -l, -I, -i/--replace, -P/--max-procs, -p/--interactive, -0/--null, -d/--delimiter, -a/--arg-file, -E, -e/--eof, --show-limits, -t/--verbose, -o/--open-tty, -r/--no-run-if-empty, -s/--max-chars, -x/--exit, --process-slot-var; -p prompts before each command and runs only for y/Y, default echo output has no trailing space; mutually exclusive -I/-i, -L/-l, and -n families use the last conflicting family and warn, except -I ... -n1; child failures map GNU-style for common cases (1..125 -> 123, 255 -> 124, not found -> 127)
Treat wildcard characters as syntax unless the operand is a file input:
grep patterns, sed scripts, jq filters, xargs input items, and
destination operands such as tee OUT or install SRC DEST stay literal.
File input operands such as grep PATTERN *.txt and sed SCRIPT *.txt
expand inside WinuxCmd.
For fixed-arity file commands such as diff, diff3, split, and
csplit, let wildcard expansion resolve to the exact number of operands the
command expects; do not guess a first match.
Keep the implementation matrix and GNU parity ledger synchronized with code
changes in the same batch.
If a command is already available as a WinuxCmd executable, prefer it over a
PowerShell alias or external fallback.
