Try this...
Code:
#!/bin/bash
while read line
do
        val=$( grep -A1 "$line" file1 | tail -1 )
        echo ${val:-null}
done < file2

In case your grep doesn't support -A option, then replace the grep line with any of these
Code:
val=$( sed -n "/$line/{n;p;q}" file1 )
#or
val=$( awk '{if($0~srch){getline;print;exit}}' srch="$line" file1 )

NAME
sccs-val, val - validate an SCCS file SYNOPSIS
/usr/ccs/bin/val - /usr/ccs/bin/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 %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 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. ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of val: LANG, LC_ALL, LC_CTYPE, LC_MES- SAGES, and NLSPATH. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWsprot | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ SEE ALSO
