Yes but it's really a bug in glob(3). It should really return
a no-match for the case in question, rather than matching and then
returning a filename without the slash.
IOW the pattern "foo\/" should not match a regular file foo.
Note that the problem doesn't occur for "foo/".
It seems like it happens for "foo/", too. If I compile:
-- >8 --
#include <glob.h>
#include <stdio.h>
int main(int argc, const char **argv)
{
while (*++argv) {
glob_t r;
if (glob(*argv, 0, NULL, &r))
perror(*argv);
else {
size_t i;
for (i = 0; i < r.gl_pathc; i++)
printf("%s -> %s\n", *argv, r.gl_pathv[i]);
globfree(&r);
}
}
return 0;
}
-- >8 --
I get:
$ rm -f foo bar
$ touch foo
$ ./a.out foo foo/ 'foo\/' bar bar/ 'bar\/'
foo -> foo
foo/ -> foo
foo\/ -> foo
bar: No such file or directory
bar/: No such file or directory
bar\/: No such file or directory
