# This code is derived from software contributed to Berkeley by
# Peter McIlroy.
#Latest version. My sort passes all tests because I wrote it.
#We differ only on 25E and 25H.
#(I found at least one bug in constructing test 25, and was driven
#to rewrite field parsing to clarify it.)
#
#In 25E, -k2.3,2.1b, the fields are not necessarily out of order.
#Even if they were, it would be legal (11752-3), although certainly
#justification for warning.
#
#On 25H, your answer is as defensible as mine. (Our suggestion
#*1 backs mine.)
# Tests for the Unix sort utility
# Test Posix features except for locale.
# Test some nonstandard features if present.
# Other tests should be made for files too big to fit in memory.
dict=/usr/share/dict/words
# Initialize switches for nonstandard features.
# Use parenthesized settings for supported features.
o=: # officially obsolescent features: +1 -2, misplaced -o (o=)
g=: # -g numeric sort including e-format numbers (g=)
M=: # -M sort by month names (M=)
s=: # -s stable, do not compare raw bytes on equal keys (s=)
y= # -y user-specified memory size (y=-y10000)
S= # -S non-stable sort
# Detect what features are supported, assuming bad options cause
# errors. Set switches accordingly.
cat <<!
Note: some sort(1) implementations (for example GNU sort) may not pass these
tests - this suite was made to fit sort(1) using (non-stable) radixsort(3),
sort(1) using other algorithm may give different results, though still
conform to standard.
