val(1) General Commands Manual val(1) Name val - validate SCCS file Syntax val - val [-s] [-rSID] [-mname] [-ytype] files Description The command determines if the specified file is an SCCS file meeting the characteristics specified by the optional argument list. Argu- ments to may appear in any order. The arguments consist of keyletter arguments that begin with a ``-'' and named files. The command 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. The command 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. Options The effects of any keyletter argument apply independently to each named file on the command line. The keyletter arguments are defined as follows: - Causes stdin to be read until end of file. -s Suppresses all error messages. -rSID Indicates specified delta version number. A check is made to determine if the SID is ambiguous, for example, r1 is ambiguous 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. -mname Compares specified value with the SCCS val.1 keyword. -ytype Compares specified type with SCCS keyword. The 8-bit code returned by is a disjunction of the possible errors. It can be interpreted as a bit string where set bits are interpreted (from left to right) as: bit 0 = missing file argument bit 1 = unknown or duplicate keyletter argument bit 2 = corrupted SCCS file bit 3 = can't 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 can process two or more files on a given command line and 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. Restrictions The command can process up to 50 files on a single command line. Any number above 50 produces a core dump. Diagnostics Use for explanations.

sccs-val, val - validate an SCCS file SYNOPSIS
val [-s] [-m name] [-rsid] [-y type] s.filename... DESCRIPTION
The val utility determines if the specified s.files meet the characteristics specified by the indicated arguments. val can process up to 50 files on a single command line. val has a special argument, `-', which reads the standard input until the end-of-file condition is detected. Each line read is indepen- dently 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, that is, it can be interpreted as a bit string where (moving from left to right) the bits set are interpreted as follows: bit 0 = missing file argument bit 1 = unknown or duplicate option bit 2 = corrupted s.file bit 3 = can not open file or file not in s.file format bit 4 = the SCCS delta ID (SID) is invalid or ambiguous bit 5 = the SID does not exist bit 6 = mismatch between Y% and -y argument bit 7 = mismatch between sccs-val.1 and -m argument 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 which is the logical OR of the codes generated for each command line and file pro- cessed. OPTIONS
The following options are supported: -s Silent. Suppresses the normal error or warning messages. -m name Compares name with the %M% ID keyword in the s.file. -rsid Checks to see if the indicated SID is ambiguous, invalid, or absent from the s.file. -y type Compares type with the %Y% ID keyword.
