The ksh_test function provides that subset of functionality of the Korn shell test(1) predicate which deals with files and their permissions. ksh_test is more flexible and has slightly different semantics than access(3) (which is frequently implemented incorrectly anyway), and is at a higher level of abstraction than stat(2).
The behavior of ksh_test matches that of the Korn shell test(1) predicate (see ksh(1)). Notice that the user need not be running ksh(1) in order for this to occur; in particular, even if the user is running another shell, the behavior of ksh_test will still match ksh(1).
Arguments to ksh_test.
enum unary{ a,r,w,x,f,d,c,b,p,u,g,k,s,L,O,G,S };
enum binary{ nt,ot,ef }; Meanings are the same as for the ksh(1) test(1) predicate. Specifically: (a) file is "stattable" (see stat(2)); (r) file is readable; (w) file has write bit on; (x) file has execute bit on; (f) file is regular; (d) file is directory; (c) file is character special; (b) file is block special; (p) file is named pipe; (u) file has set-user-id bit on; (g) file has set-group-id bit on; (k) file has sticky bit on; (s) file is non-empty; (L) file is symbolic link; (O) file owner is effective user id; (G) file group is effective group id; (S) file is socket; (nt) p1 is newer than p2; (ot) p1 is older than p2; (ef) p1 is another name for p2.
enum id{ effective,real }; Specifies the id against which the tests are to be made.
const char* file, Ksh_test::id id = Ksh_test::effective ); Equivalent to ksh_test(Ksh_test::a, file, id).
Ksh_test::unaryt," constchar*file," Ksh_test::idid=Ksh_test::effective" ); Equivalent to the ksh(1) expression test -t file, where id is the user id against which the test is made.
const char* file1, Ksh_test::binary t, const char* file2, Ksh_test::id id = Ksh_test::effective ); Equivalent to the ksh(1) expression test file1 -t file2, where id is the user id against which the test is made.
