POSIX Tools (v0.2.7)

26 core POSIX utilities implemented in the Aria programming language, located in tools/. All tools support standard Unix pipelines (cat file | grep pattern | wc).

File Utilities

Tool	Description
cat	Concatenate and display files
head	Display first N lines (default 10)
tail	Display last N lines (default 10)
wc	Word, line, and character count
tee	Duplicate stdin to stdout and files
cut	Extract fields by delimiter
sort	Sort lines lexicographically
uniq	Remove adjacent duplicate lines
tr	Translate characters

Search & Filter

Tool	Description
grep	Substring pattern search
find	Check file existence
diff	Compare files line-by-line

System Utilities

Tool	Description
echo	Output text
yes	Repeatedly output a line
true	Exit with code 0
false	Exit with code 1
env	Environment display (placeholder)
sleep	Pause execution
basename	Extract filename from path
dirname	Extract directory from path
seq	Generate number sequences

Text Processing

Tool	Description
nl	Number lines
fold	Wrap long lines at width
paste	Merge lines from files
expand	Convert tabs to spaces
unexpand	Convert leading spaces to tabs

Building

All tools are compiled with the Aria compiler (ariac):

ariac tools/cat.aria -o cat
ariac tools/grep.aria -o grep

Pipeline Support

All tools read from stdin when no file argument is given:

cat file.txt | grep "pattern" | sort | uniq | wc
echo "hello world" | tr "aeiou" "AEIOU" | nl
cat data.txt | head -n 5 | tee output.txt

Six-Stream I/O

Tools are designed with the AriaX six-stream I/O model in mind:

• stdin (0), stdout (1), stderr (2) — standard streams
• stddbg (3), stddati (4), stddato (5) — extended streams

Stream routing is a single configurable point per tool. When AriaX kernel support is ready, switching to six-stream is a configuration change, not a rewrite.
