Hi, anyone has any idea how to merge two files vertically, meaning first line of file1 merge with first line of file2, second line of file1 with second line of file2... regards, y

One quick and dirty way would be: #!/bin/ksh typeset -i RecordA=0 typeset -i RecordB=0 typeset -i RecordCountA=0 typeset -i RecordCountB=0 typeset -i Rest=0 InfileA=/u/a1xrdb1/i InfileB=/u/a1xrdb1/x RecordA=`wc -l ${InfileA} | awk '{print $1}'` RecordB=`wc -l ${InfileB} | awk '{print $1}'` while [ ${RecordA} -gt ${RecordCountA} -a ${RecordB} -gt ${RecordCountB} ] do RecordCountA=RecordCountA+1 RecordCountB=RecordCountB+1 RowA=`head -${RecordCountA} ${InfileA}|tail -1` RowB=`head -${RecordCountB} ${InfileB}|tail -1` echo ${RowA} ${RowB} done if [ ${RecordCountA} -lt ${RecordA} ] then Rest=RecordA-RecordCountA tail -${Rest} ${InfileA} fi if [ ${RecordCountB} -lt ${RecordB} ] then Rest=RecordB-RecordCountB tail -${Rest} ${InfileB} fi no Risk no fun Frank

paste file1 file2 > file12
