val - validate an SCCS file
val [-s] [-mname] [-rsid] [-ytype] s.filename...
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 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.
-s Silent. Suppresses the normal error or warning messages. -mname 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. -ytype Compares type with the %Y% ID keyword.
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 %M% 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 processed.
