Top Forums Shell Programming and Scripting Need shell script to read two file at same time and print out in single file Post 302295395 by mjd_tech on Saturday 7th of March 2009 10:11:18 PM

There are probably a million better ways to do this...
but here goes...
Code:
#!/bin/sh
linecount1=$(wc -l file1.txt | cut -d\  -f 1 )
linecount2=$(wc -l file2.txt | cut -d\  -f 1 )
i=1 j=1
while [ $i -le $linecount1 -a $j -le $linecount2 ]; do
    sed -n -e "${i}p" file1.txt >> output.txt
    sed -n -e "${j}p" file2.txt >> output.txt
    echo "-----" >> output.txt
    i=$(( i + 1 )); j=$(( j + 1))
done

I had to do the cut stuff when assigning linecount, because my wc -l prints the file name after the number of lines. (Debian)

MD
