Shell Programming and Scripting

Hello,

I read a file whose in lines are datas and between thses datas there is blank characters (10, 12 or 5 or 1 .......)

So when i use the command while read line in the script(see under) there is also only one character between the datas and the others blank characters are not here.

exec <$IN_DIR/${filename}

while read line ; do
echo $line
if [ $(echo ${#line}) -gt 157 ] ; then
exec 2>$IN_DIR/${filename}.$(echo $line | cut -c,158-160)
fi
echo $line>&2
done

So here is an example with the original datas with all the blank characters

5712900014 00001000 CHF00000003020720030000900009+000000149935+000000147782+000000000150+000000001980+00000000002301D09


This is the example when i read with :while read line

5712900014 00001000 CHF00000003020720030000900009+000000149935+000000147782+000000000150+000000001980+00000000002301D09


Perhaps there is an option who take the original datas and put it in the line (while read line...)

Has anyone a idea.. Thanks a lot....

Enclose $line in quotes:
echo "$line"

And is
$(echo ${#line})
really what you meant to do? If $line is 10 characters long, you're going to end up with the variable $10, which will give an error. Just use the one part to return the length of the line:
${#line}

In ksh, $(echo ${#line}) is close to `echo ${#line}` so the statement:
if [ $(echo ${#line}) -gt 157 ] ; then
is perfectly valid, although it's a bit like walking around the world to get across the street. I agree that a sensible approach might be:
if [ ${#line} -gt 157 ] ; then

Hello,

Thanks for your answers.

So I find if a put in my script the IFS= , it take the line so that are in the original file.

It's work good..

So have a lot of thanks ... Bye...
