Taking this, and making that

  • 772

I had no idea how to word the title.

I need to take an output such as:

[~]# cat file
user1
domain1.com
user2
domain2.com
user3
domain3.com

and turn it into an output such as:

user1 domain1.com
user2 domain2.com
user3 domain3.com

Any assistance here would be greatly appreciated.

linux shell sed

    #!/bin/bash

while read user
do 
        read domain
        echo $user $domain     
done

    usage:

    cat file | scriptname

  2. I figured this out with some array-age

    for i in `seq 1 2 ${#array[@]}` ; do echo "${array[$i]} ${array[$i + 1]}"; done

  3. Man, there's gotta be an easy way to do this. I clearly haven't got enough sleep, because I can't think of any. But, because I don't like arrays, I used a for loop. It essentially goes through each LINE, and outputs the even numbers to a new file without a linebreak, and appends the odd ones with a break. Seems to work!

    COUNT=0
for LINE in $(cat file.txt);do
  if [ $(($COUNT % 2)) -eq 0 ];then 
      echo -n $LINE >> newfile.txt
      echo -n " " >> newfile.txt
  else
      echo $LINE >> newfile.txt
  fi
COUNT=$((COUNT + 1))
done
