Abstract: Following is a brief summary of highlights:

DISK AND DIRECTORY UTILITIES

• COMPRESS - Gain wasted disk space from over-allocated files.
• DELDIR - Makes deleting directories very easy. Take care of all files and subdirectories as well. Only requires CONTROL access to the files and write access to the directory.
• DELZER - Delete zero length files.
• DISK - Shows free disk space for all disks; (F87:longer disk names), (S88: shadowset support), (F88: misc fix when SHO DEV is more than one line per disk as in Mounted MountVerification Timeout).
• SYSFILES - Looks at your page and swap file utilization, and makes a recommendation for a new size if the files are too small.
• REVIEW - Makes cleaning up directories much easier. REVIEW asks about each file matching the input wildcard filespec (default is all) giving the option of typing, editing, deleting, or moving the file. You may also issue any DCL command (such as DUMP or SPAWN). Great for cleaning out old files from directories.
• DRAWTREE - Draw the directory tree - previous Encompass submission patched to default to SYS$LOGIN.
• DOWN - Go down directory tree.
• UP - Go up directory tree.

SYSTEM SECURITY UTILITIES

• SECAUDITWILD - Uses SYS$MANAGER:SECAUDIT.COM to get security alarm information, but allows wildcard file specs. For example, this will get the last weeks alarms, even if you have re-booted several times.
• SYSCHECKSUMS - Check checksums for all files in SYS$SYSTEM. It produces a differences list with all of the changes.
• ACCSUM - Accounting summary of current accounting file. We set a new accounting file each week, and keep the old ones for a year.
• CHKLOGTIM - Show processes logged in over a certain time. Helpful for spotting people logged in overnight, etc. Even though we run Watchdog, there are easy ways to circumvent being logged off. This might even be modified to stop processes over a day old.
• CHKPRI - Check process priorities.
• LOOK - Look at process quotas.
• SAFE - Create a "safe" non-privileged environment.

TERMINAL UTILITIES

• VT2XXDEF - Download key definitions to a VT200 series terminal - really nice for setting up terminal servers and for use within programs where there is no access to DCL DEFINE/KEY definitions.
• DS200DEF - A version of VT2XXDEF which has been modified especially for setting up new systems with multiple DECservers. It defines the keys necessary for defining interactive and printer ports. Directions for use are found at the end of the procedure.
• OKI - Print a file on an attached printer. (Called OKI here because we use mainly Okidata printers on printer ports.)
• WIDE - 132 column TYPE.

SHARED IMAGE UTILITIES

• FINDIMAGES - Give it image names, and it finds all shared images they are linked against.
• FINDIMAGEVER - Same as FINDIMAGES but also includes image versions.
• FINDSHAREVER - Give it shared images, and it finds the image versions.
• SAVCURVER - Save current VMS version shared images and linker.
• USEPREVIOUS - Use a previously saved version of the shared images and linker. Note that some of the images must be INSTALLed afterward in order to work. Also, the logicals are defined in the job table. You may need to increase JTquota or change them to process table logicals to work correctly.
• NOUSEPREVIOUS - Un-does the work done by the last command procedure so you don't have to log out or deassign all logicals. (If you distribute software to customers who may not keep current with VMS versions, it may not run. These command procedures aid in being able to send them a set of software which will run. May be especially useful for V5 to V4 shipping if you use SAVECURVER on V4.7 before you upgrade. It's also interesting to see what images VMS utilities are linked against.

MISELLANEOUS UTILITIES

• EDTWILD - Wildcard file editing.
• RESTORE - Restore file(s) from a backup tape.
• BINARY - SHOW SYMBOL showed binary as well as decimal, octal, and hexadecimal.
• TWO_SIDE - Prints a file on both sides of the paper. This program splits a file into two files: front and back. One caution: at one point, half the file will be in memory. We have used this with large (>300page) files with no problems. The object file is included for those without PASCAL compilers who may wish to re-link the image. Just print the front, turn the paper over, and print the back.
