Insert a decimal point

Shell Programming and Scripting

Hi all. Using /bin/sh on an HPUX system.

I want to place a decimal in the field 2 charactors from the right (yes, converting to currency). The field lengths are variable. Here's what I'm doing:

exec < filename
while read FIELD1 FIELD2
do
FIELD1="echo $FIELD1 | sed 'syntax that will insert . 2 chars before rightmost' "
done

Thanks in advance!!!!!

echo '12345' | sed 's/..$/.&/'

If number may be one digit only, you can use this sed command :

echo "1234" | sed 's/..$/.&/;t;s/^.$/.0&/'  -> 12.23
echo    "1" | sed 's/..$/.&/;t;s/^.$/.0&/'  -> .01

On my AIX box, i have a problem with the 't' command inside sed (all the string after t is considered as being the label to branch to). If you have the same problem, you can remove the 't;' part.
