Synopsis

filetest [-L] [-b] [-c] [-d] [-e] [-f] [-g] [-h] [-k] [-l] [-p] [-r] [-s] [-u] [-w] [-x] [-z] string

filetest is NOT undoable, NOT queryable, and NOT editable.

The unary negation operator, "!", may precede the test.

Special Note:

If you test a file you own (the -r, -w, or -x tests), but the permission tested does not have the owner bit set, a non-zero (false) exit status will be returned even though the file may have the group or other bit set for that permission. The correct exit status will be set if you are super-user.

If more than one test is specified, only the first test is executed; the others are ignored.

Note that while filetest is similar to the "test" cmd from the unix shell, /sbin/test, it is not the same. Only a single test is allowed, not all options are supported, and the return code is reversed -- true returns 1 in filetest, but 0 in the shell.

MEL examples

// Test whether the temp directory exists
//
string $tmpDir = `internalVar -userTmpDir`;
filetest -d $tmpDir;
// Result: 1 //

// The following will fail because the temp dir is not a regular file
//
filetest -f $tmpDir;
// Result: 0 //
