Determining File Types
Before you try to work with a file created using HFS syntax, you may need
to determine what type of file it is. Use the LISTFILE command with the
,2 option to list compete information about a file. The TYP field
indicates the type of file it is and whether it is a directory.
Using LISTFILE, 2 produces output such as the following:
__________________________________________________________________________
| |
| |
| <user |listfile /OFFICIAL/GP1,2| |
| PATH= /OFFICIAL/ |
| |
| CODE ------------LOGICAL RECORD----------- ----SPACE---- |
| FILENAME |
| SIZE TYP EOF LIMIT R/B SECTORS #X MX |
| |
| 0 GBD 0 0 0 64 2 * GP1/ |
| |
__________________________________________________________________________
The TYP field uses letters to represent types of files. In the example
shown here, the TYP field contains GBD indicating that it is a group
directory.
Table 7-2 defines letter codes that can appear in the TYP field.
