Hi there,
1. open the file using vi
2. press : to go to command line.
3. enter command s/xxxxxxxxxxxx/xxxx.xxxx.xxxx/g
4. :wq!
to save and exit.
that's all.

Regards,

I think this user wants to insert .'s in the string.

This is a nasty way of doing it but it's all I can come up with at the moment.

STRING="123456789abcdefg";

a=`echo $STRING | cut -c1-4`
b=`echo $STRING | cut -c5-8`
c=`echo $STRING | cut -c9-12`
d=`echo $STRING | cut -c13-16`

echo "$a.$b.$c.$d"

Sorry, didn't realise you had a file of these and I over-did how many you want.

Here's another nasty one (sorry Merijn) that does your whole file.

perl -ne '($a,$b,$c)=($_=~/^(....)(....)(....)/);print "$a.$b.$c\n"' datafile

The solution by harry is the best one to start with because it's general: that command will substitute every kind of string (x can be any char)
Describe better what u need to subst, for instance:

# sed "s/^$.\{4\}$$.\{4\}$$.\{4\}$/\1.\2.\3/" < file1 > file2

would change the beginning of every line of file1 in that way, writing the new file file2
while

# sed "s/$.\{4\}$$.\{4\}$$.\{4\}$$/\1.\2.\3/" < file1 > file2

would change the ending part of every line of file1

If you need to change in the middle you must specify better the subst you need, even with some line of example

hope this helps
Cesare

# export x=blah
# perl -pe 's/....(?:.)/$&$ENV{x}/g' your_file
512dfblah456rtblah89
789gfblahd18gfblah86
12fy5blah6cd22blah96
789fyblah12htyblah89
#

Maybe even clearer with

# env x=. perl -pe 's/....(?:.)/$&$ENV{x}/g' your_file
512df.456rt.89
789gf.d18gf.86
12fy5.6cd22.96
789fy.12hty.89
#

Enjoy, Have FUN!

Two alternatives. The first keeps things in the shell and is the most efficient:

while read line
do
var1=${line%????????}
var3=${line#????????}
var2=${line%$var3}
var2=${var2#$var1}
echo "${var1}.${var2}.${var3}"
done < filename

The second uses awk:

awk '{print substr($0,1,4} "." substr($0,5,4} "." substr($0,9)}' filname
