Code:
$ cat test.file
123andsomeothervalues with a space at position 22
Not 123 but with the  space
123 but no spacein the appropriate column

$ perl -npi.bak -e 's/^(123.{18}) /$1X/' test.file

$ cat test.file
123andsomeothervaluesXwith a space at position 22
Not 123 but with the  space
123 but no spacein the appropriate column

If the space is in position 800, then there a 799 characters before it not 800 so the quantifier should be 796 ie:
Code:
perl -npi.bak -e ' s/(123.{796}) /${1}X/' infile

Perhaps my ability to count was compromised by a dangerous caffeine deficiency, currently remedying this cU.
