hi...
doing some testing with linux sha1sum, and php's sha1 function... are
they both supposed to return the same results for the same chunk of
text.
test
file "a.dat" = "1234567890"
linux:
echo a.dat > sha1sum -t != php <? sha1("1234567890"); ?>
any thoughts...
Try "echo -n"
While you've got the right approach, the original command has three (yes
3!) different problems!!!
1. echo automatically appends a new line. Using echo -n will prevent this.
2. You have a file, echo a.dat will echo the file *name* a.dat not it's
contents. You probably want to use "cat" instead.
3. You care redirecting (>) rather than piping (|).
So waht you really want is:
cat a.dat | sha1sum
(the -t is not needed).
You can also do:
echo -n "1234567890" | sha1sum
