Data echo omits slash - how to avoid
Hi,

I have a file which contains as follows,

a.tmp
Test \13\
Hello

When i read the file and print the ouput using echo, "\" is not coming. How to avoid it.

here goes the script
a.sh
-----
while read line
do
echo $line
done < a.tmp

Output is:
Test 13
Hello

I need "\" to appear in the output.

Any ideas, please help.

Thanks,
Om

here goes the solution,

read -r <line> will not take the backslash character in account.

cheers,

Or you could use a backslash to escape your backslash, like this

Test \\13\\

Or you could put quotes around that line to get it to ignore the backslashes.

Incorrect output from script
To have the script include the "\" character I would re-write it so that the condition echo $line is replaced by echo "\$line\". In this way the reverse virgules should appear on either side of the line number.

Good luck!
