VAL(1SCCS) COMMAND REFERENCE VAL(1SCCS)
NAME
val - validate SCCS file
SYNOPSIS
val -
val [-s] [-rSID] [-mname] [-ytype] filenames
DESCRIPTION
Val determines if the specified filename is an SCCS file
meeting the characteristics specified by the optional
argument list. Arguments to val may appear in any order.
The arguments consist of keyletter arguments, which begin
with a dash (-), and named files.
Val has a special argument, -, which causes reading of the
standard input until an end-of-file condition is detected.
Each line read is independently processed as if it were a
command line argument list.
Val generates diagnostic messages on the standard output for
each command line and file processed and also returns a
single 8-bit code upon exit as described below.
The 8-bit code returned by val is a disjunction of the
possible errors; for example, it can be interpreted as a bit
string where (moving from left to right) set bits are
interpreted as follows:
bit 0 = missing file argument
bit 1 = unknown or duplicate keyletter argument
bit 2 = corrupted SCCS file
bit 3 = cannot open file or file not SCCS
bit 4 = SID is invalid or ambiguous
bit 5 = SID does not exist
bit 6 = %Y%, -y mismatch
bit 7 = %M%, -m mismatch
Note that val can process two or more files on a given
command line and in turn can process multiple command lines
(when reading the standard input). In these cases an
aggregate code is returned -- a logical OR of the codes
generated for each command line and file processed.
OPTIONS
-mname
The argument value name is compared with the SCCS %M%
keyword in filename.
-rSID
The argument value SID (SCCS IDentification String) is
an SCCS delta number. A check is made to determine if
the SID is ambiguous (for example, r1 is ambiguous

VAL(1SCCS) COMMAND REFERENCE VAL(1SCCS)
because it physically does not exist but implies 1.1,
1.2, and so forth, which may exist) or invalid (for
example, r1.0 or r1.1.0 are invalid because neither case
can exist as a valid delta number). If the SID is valid
and not ambiguous, a check is made to determine if it
actually exists.
-s The presence of this argument silences the diagnostic
message normally generated on the standard output for
any error that is detected while processing each named
file on a given command line.
-ytype
The argument value type is compared with the SCCS %Y%
keyword in filename.
DIAGNOSTICS

CAVEATS
Val can process up to 50 files on a single command line.
