#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.)

|
|
# 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.

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.
