Shell Programming and Scripting

Hi experts,

Need your help on how to insert carriage return after the 10th char position of each line in a file and then add two blank spaces after the carriage return.

Example:

Code:

>cat test.txt
testingline
dummystring
samplesample
teststringline

Expected output should be..

Code:

testinglin
  e
dummystrin
  g
samplesamp
  le
teststring
  line

i am currently using the "cat test.txt| while read line and then some cut commands" but im thinking of other commands that can produce the same output.

Thank u in advance!

I presume you mean linefeed instead of carriage return. You could try sed:

Code:

sed 's/./\
  &/11' infile

Thanks Scrutinizer!!
