Prashant Jain · #1 (**permalink**) 3 Weeks Ago

i have a file like::
$ cat space
asd
fghj
itkg

now i want to replace the next line with . and thn this . with the 100 spaces.

cat space | tr '\n' '.', it woked for me, to replce the new line to .

Now i want to replace this . with 100 spaces.

I guess you mean "newline" and not "next line".
Why an additional step in between ? Why not replace newlines with 100 spaces directly ?

Again, why substitute by the "." first ?

If directly we can do it, it will be great. Can you please send me the command.

Do you want to replace the last character with 100 spaces?

Code:

cat fichero | sed "s/$/`perl -e 'print \" \" x 100'`/"

Or using just Perl:

Code:

$
$ cat space
asd
fghj
itkg
$
$ perl -ne '$x = " "x10; s/\n/$x/g; print' space
asd          fghj          itkg          $
$
$

Replace 10 by 100 in the one-liner above.

Here i hope no need to use "cat".

Thanks tyler_durden, it worked

Now there is one more issue, in some lines i have 10 charactes & in some there are 20chars.
no. of spaces should be 200 - number of character in a line.

if No. of chars are 20 thn there should be 180 spaces.

please help me on this also.

Thanks in advance
