How to read a text file line by line as a string 2

[kimmers]

Howdy,

I am trying to make a script which first greps 'failed' messages and puts them into file.

Then I need to read each line and send them i.e as a separate mailx message.
Here first tested with echo-command to see the output:

So how to read a line as a string so that it would handle each row as a entire line.
/tmp/logfile.log (looks like this)

" Login for user xxxx failed "
" Login for user yyyy was ok "
" Login for user zzzz failed "

============================

#!/bin/sh

grep failed /tmp/logfile.log > /tmp/failed.log

for i in `cat /tmp/failed.log`
do
echo $i
done

Output should look like this
" Login for user xxxx failed "
" Login for user zzzz failed "

but it looks like this
"
Login
for
user
xxxx
failed
"
"
Login
for
user
zzzz
failed
"

------------
So I wonder how to fix this prob,

Hi Kimmers,
change line for i in `cat /tmp/failed.log`
to
while read i

and line done
to
done < /tmp/failed.log

Hi kimmers,

Do it in this way :

grep failed /tmp/logfile.log > /tmp/failed.log

cat /tmp/failed.log | while read ln
do
echo $ln
done

Best Regards,
