# Show your current default directory:

SHOW DEFAULT

# Change directory (like cd):

SET DEFAULT [DIRECTORY]

SET DEFAULT DKA0:[JOE.SUBDIR]

# Go up one directory level (like cd ..):

SET DEFAULT [-]

Go up two levels:

SET DEFAULT [--]

Go up one level then into a sibling directory:

SET DEFAULT [-.SUBDIR]

# List files (like ls):

DIRECTORY

Full details (size, date, protection):

DIRECTORY /FULL

Just filenames, no header/footer (good for scripting):

DIRECTORY /BRIEF /NOHEADER /NOTRAILING

Recursively list subdirectories:

DIRECTORY [...]

Wildcards work as expected:

DIRECTORY *.COM

# Create a directory (like mkdir):

CREATE /DIRECTORY [.NEWDIR]

Create with an owner UIC set:

CREATE /DIRECTORY DKA0:[TESTUSER] /OWNER=[200,#]

# Remove a directory (must be empty; delete the .DIR file itself):

SET DEFAULT [-]

DELETE NEWDIR.DIR;1

# Copy a file (like cp):

COPY OLDFILE.TXT NEWFILE.TXT

Copy into another directory, keeping the name:

COPY OLDFILE.TXT [.SUBDIR]

Copy an entire directory tree:

COPY [SOURCE...]*.* [DEST...] /LOG

# Rename/move a file (like mv):

RENAME OLDNAME.TXT NEWNAME.TXT

Move to another directory (rename across dirs works fine in VMS):

RENAME FILE.TXT [.SUBDIR]FILE.TXT

# Delete a file (like rm):

DELETE FILE.TXT;1

Delete all versions of a file:

DELETE FILE.TXT;*

Delete with wildcard, prompting for each:

DELETE /CONFIRM *.TMP;*

# Purge old file versions (VMS keeps multiple versions by default):

PURGE FILE.TXT

Purge everything in current directory, keeping only 2 versions:

PURGE /KEEP=2 *.*

# View a file's contents (like cat):

TYPE FILE.TXT

Page through a file (like more/less):

TYPE /PAGE FILE.TXT

# Search inside files (like grep):

SEARCH FILE.TXT "searchstring"

Search across multiple files:

SEARCH *.LOG "ERROR"

# Compare two files (like diff):

DIFFERENCES FILE1.TXT FILE2.TXT

# Append to a file:

APPEND NEWSTUFF.TXT EXISTING.TXT

# Show file protections/ownership:

DIRECTORY /SECURITY FILE.TXT

# Change file protection (like chmod):

SET PROTECTION=(OWNER:RWED,GROUP:RE,WORLD:RE) FILE.TXT

# Change file owner (like chown):
