Maybe you won't. KILL0 will delete files with 0 blocks. It will not delete files which are open or which have a protection code of <63> or which have the "protect" bit set (see PROBIT below). Otherwise, it automatically deletes the file. BIGFIL locates and optionally deletes large files. The user specifies a size and the program lists all files whose size is larger than or equal to the given size. The program has three deletion options: delete them all, delete none (but list them), and ask about each file. PROBIT can set and clear the "protect" bit on a file. When the protect bit is set on a file, that file can not be deleted or renamed even by a privileged user. However, the contents of the file can be changed. CLASS creates or deletes a range of accounts. It is designed for class accounts each of which has the same quota and same (initial) password. The program has a data file which has a list of the course numbers and the corresponding projects. Obviously, you will want to change the data. The program keeps track of how many accounts were created so that it can delete the accounts without having to ask you how many there were. The program will also tape the accounts (by creating a command file for PIP). ACCLST gives a list of all the accounts on the system in a compact format. No information is given about the accounts. PACKID allows you to change the ID of a disk pack. PRIV gives a list of all files which have a privileged protection code. LAST accesses the "last logged in" data in the GFD for specific accounts, keyboards, and dates. User may specify a list of accounts, each one of which may contain an * for project or programmer number. For example: [1,*],[51,2],[*,0]. User may specify as list of keyboard numbers, each entry of which may be an individual keyboard or a range of keyboards. For example: 12,14-19,20. The user may specify dates in three formats: date, BEFORE date, and date1 TO date2. The program will print out the "last logged in" data only for cases matching all three specifications. Of course, each one defaults to "ALL". WARNING: this program can not be used to find out who last used a given keyboard. The person who last used a given keyboard may have subsequently used another keyboard. The program can only list those people who have not used another keyboard since the specified one. PROTEC is a program designed to reserve a terminal for a short time. It is designed for workers in the computer center who wish to leave their terminal for a short time but do not want to sign out and sign back in. The program "locks" the keyboard by "eating" all input, including control C. Program terminates when the correct password is given. If time runs out, the program logs itself out. It is normally reserved for privileged users, but the "permission file" for JUMP is also a permission file for PROTEC. MFDBIT will set the "marked for deletion" bit on a file, making it partially invisible. PIP and DI do not ordinarily list such file, making it likely that no one will notice them. DI/S will list them. When the disk is CLEANed, the files will be deleted, so the effect can only be used temporarily. FIND will list all the files which have this bit set. GFD and UFD access the data in the GFD and UFD. The data itself is not really the point. The real purpose of the programs is to show how to access the data. BFD is included just for fun. DATETI shows how to access the data in the Date Time blockette of the GFD. Several of the programs in this package access either the MFD, GFD, or UFD. One of them accesses the Pack Label Block. The text files MFD.DOC, GFD.DOC, UFD.DOC, and PACK.DOC are explanations of them. Please let me know if the explanations are insufficient.
