Display two files side by side in linux

Have you ever needed to display cat content of two files side by side on terminal, if yes you are right place :)

You have following options :



1. Vimdiff :
        Edit two, three or four versions of a file with Vim and show differences, just play with 'man vimdiff' for more options.

Eg : vimdiff file1 file2

2. Paste :
       Merge lines of files, go for 'man paste' for more options.

Eg : paste file1 file2

3. Pr :
     Convert text files for printing, do 'man pr' for more detail.

Eg : pr -m -t -W 100 brl gndcfile
     

• -m, --merge     

               Print all files in parallel, one in each column,

• -t, --omit-header  

               Omit page headers and trailers

• -w, --width=PAGE_WIDTH

               Number of characters per page

4. sdiff :
          side-by-side merge of file differences, do 'man sdiff' for more detail

Eg: sdiff file1 file2

5. Using awk command:

Eg:

awk 'BEGIN{print "Column1\tColumn2"} {getline a < "file2";printf "%-40s\t%s\n",$0,a}' file1
