Can someone tell me what is wrong with this #!/bin/ksh set -x grep { while read -r data do echo $data grep -c Position $data > file if [ -s file ]; then TABLES=Position grep -c Participant $data > file elif [ -s file ]; then TABLES=Participant grep -c PosRelation $data > file elif [-s file ]; then TABLES=PositionRelation else print "ERROR in batch file incorrect data..\n" #exit 1 fi done } < batch_partpos.parm I am expecting it to look for each of the three names in the file and set the variable accordingly. However I get these error: + < batch_partpos.parm + read -r data + echo Position_02312007_123456 Position_02312007_123456 + grep -c Position Position_02312007_123456 + > file grep: Position_02312007_123456: No such file or directory + [ -s file ] + [ -s file ] + [-s file ] test[15]: [-s: not found + print ERROR in batch file incorrect data..\n ERROR in batch file incorrect data.. + read -r data + echo Participant__02312007_123456 Participant__02312007_123456 + grep -c Position Participant__02312007_123456 + > file grep: Participant__02312007_123456: No such file or directory + [ -s file ] + [ -s file ] + [-s file ] test[15]: [-s: not found + print ERROR in batch file incorrect data..\n ERROR in batch file incorrect data.. + read -r data + echo PosRelation_02312007_123456 PosRelation_02312007_123456 + grep -c Position PosRelation_02312007_123456 + > file grep: PosRelation_02312007_123456: No such file or directory + [ -s file ] + [ -s file ] + [-s file ] test[15]: [-s: not found + print ERROR in batch file incorrect data..\n ERROR in batch file incorrect data.. + read -r data + echo Position_02312007_223456 Position_02312007_223456 + grep -c Position Position_02312007_223456 + > file grep: Position_02312007_223456: No such file or directory + [ -s file ] + [ -s file ] + [-s file ] test[15]: [-s: not found + print ERROR in batch file incorrect data..\n ERROR in batch file incorrect data.. + read -r data + echo Participant__02312007_223456 Participant__02312007_223456 + grep -c Position Participant__02312007_223456 + > file grep: Participant__02312007_223456: No such file or directory + [ -s file ] + [ -s file ] + [-s file ] test[15]: [-s: not found + print ERROR in batch file incorrect data..\n ERROR in batch file incorrect data.. + read -r data + echo PosRelation_02312007_223456 PosRelation_02312007_223456 + grep -c Position PosRelation_02312007_223456 + > file grep: PosRelation_02312007_223456: No such file or directory + [ -s file ] + [ -s file ] + [-s file ] test[15]: [-s: not found + print ERROR in batch file incorrect data..\n ERROR in batch file incorrect data.. + read -r data
