Shell Programming and Scripting

HI all,
i have a input file,i have to join 2nd line into firstline and 4th line into 2nd line and so on..
for this we also consider odd no. of line.It's operate on original input file but output file should temp file.
like ..
filename=cdr.cfg

Code:

line1
line2
line3
line4

Desired output should be like this...
filename=temp.cfg

Code:

line1line2
line3line4

If odd no. of lines are in file,then output should be like this..

Code:

line1line2
line3

Hi,

Try this:

Code:

$ perl -pE 's/\n// if ($. % 2);' infile

Regards,

Try this,

Code:

paste  -d '' - -  < inputfile

Request you to use code tags icon to wrap your input/output files for better readability.

Code:

awk '{r=$0;print v=getline? r $0:r}' inputfile > outfile

use the paste command
as paste 1st filename 2nd filename

Code:

$ ruby -ne 'print ($.% 2==0)?$_ : $_.chomp!' file 
line1line2 
line3line4

Code:

sed 'N;s/\n//'
