— Action: -ls

True; list the current file in ls -dils format on the standard output. The output looks like this:

          204744   17 -rw-r--r--   1 djm      staff       17337 Nov  2  1992 ./lwall-quotes
     

The fields are:

1. The inode number of the file. See Hard Links, for how to find files based on their inode number.
2. the number of blocks in the file. The block counts are of 1K blocks, unless the environment variable POSIXLY_CORRECT is set, in which case 512-byte blocks are used. See Size, for how to find files based on their size.
3. The file's type and permissions. The type is shown as a dash for a regular file; for other file types, a letter like for -type is used (see Type). The permissions are read, write, and execute for the file's owner, its group, and other users, respectively; a dash means the permission is not granted. See File Permissions, for more details about file permissions. See Permissions, for how to find files based on their permissions.
4. The number of hard links to the file.
5. The user who owns the file.
6. The file's group.
7. The file's size in bytes.
8. The date the file was last modified.
9. The file's name. -ls quotes non-printable characters in the file names using C-like backslash escapes.

— Action: -fls file

True; like -ls but write to file like -fprint (see Print File Name).

— Action: -printf format

True; print format on the standard output, interpreting \ escapes and % directives. Field widths and precisions can be specified as with the printf C function. Format flags (like # for example) may not work as you expect because many of the fields, even numeric ones, are printed with %s. This means though that the format flag - will work; it forces left-alignment of the field. Unlike -print, -printf does not add a newline at the end of the string. If you want a newline at the end of the string, add a \n.

— Action: -fprintf file format

True; like -printf but write to file like -fprint (see Print File Name).
