Hi,

I have an requirement of reading a long line of 7000 chars and cutting it

iam doing this :

while read -r x
do
echo $x

.........
done < `cat filename`

when iam doing this it is giving me "0403-016 Cannot find or open the file."

Can anyone let how this can be done.

The whole UUOC is throwing things out of whack....

while read whatever; do
# whatever
done < filename

Depending on your shell, you may well encounter limits with a line that long anyway....

On a modern shell like bash (on Linux), this copes quite well

$ for i in `seq 1 7000`
>   echo -n "a" >> longline
> done
$ echo "" >> longline
$ wc -c longline
      7001   longline
$ while read line; do
>   echo ${line} 
> done < longline
aaaaaaaaa.....
.
....aaaaaaaa
$

For the line,

echo $x

Think about what could happen if there is semicolon/quote/comma within $x.
You may want to try, in bash
echo -E "$r"
