Awk or sed to display increment odd & even lines

Question

Need help to display increment odd & even lines in a text file to screen.

Textfile

10101 
AsPO4IF+tGU=
01010 
WvTzUYrxvXY=
00101
CfZzsDDKW98=

Stuck at the following script.

result=Textfile
while IFS='' read -r line || [[ -n "$line" ]];
echo "`awk or sed odd line $result`" "`awk or sed even line $result`"
done < "$result"

Output needed

"AsPO4IF+tGU=" "10101" 

"WvTzUYrxvXY=" "01010" 

"CfZzsDDKW98=" "00101" 

Stops script once EOF in Textfile has reached.

Thanks for your time.

Answer 1

You don't need to loop lines of a file, awk is expert in exactly that:

awk '
    NR%2 != 0 {last=$0}
    NR%2 == 0 {printf "\"%s\" \"%s\"\n",$0,last}
' file

Answer 2

With sed you don't need to have an external loop either:

sed -E '$!N;s/(.*)\n(.*)/"\2" "\1"/' file

• -E is to use extended regular expression, which makes the ()easier to read
• $!N always joins (N) two lines in the pattern space except for the last line ($!), if there should be an unpaired line
• s/(.*)\n(.*)/"\2" "\1"/ flips both lines, replaces the newline with a whitespace and adds the double quotes

Answer 3

I have done by below method

command:

sed "N;s/\n/ /g" filename | awk '{print $2,$1}'| sed 's/^/"/g'| sed 's/$/"/g'| sed 's/=/"&"/g'

output

"AsPO4IF+tGU"=" 10101"
"WvTzUYrxvXY"=" 01010"
"CfZzsDDKW98"=" 00101"
