You could enter the value as '\svlipc32\masters\xxxx' (with the quotes)

use -r

Code:

$ read -r s
\svlipc32\masters\xxxx
$ echo $s
\svlipc32\masters\xxxx
$read s #without -r 
\svlipc32\masters\xxxx
$ echo $s
svlipc32mastersxxxx

Dear friends,

how to do this in shell scripts. any solution for this or no solution.

My input will be : \svlipc32\masters\xxxx ,\\svlipc32\\masters

my output should be : \svlipc32\masters\xxxx,\\svlipc32\\masters but its coming as svlipc32mastersxxxx and \svlipc32\masters

presently iam giving i/p as \\svlipc32\\masters\\xxxx to get this
\svlipc32\masters\xxxx

Read Val
echo " Enter the input string \n"
echo $val
please help me in this.

if I use -r read :

read -r val
echo $val

if i give this as input thats ok :- \svlipc32\masters\xxxx

but if i give this \\svlipc32\\masters as input iam getting \svlipc32\masters not as \\svlipc32\\masters.

Works for me:

Code:

c:~$ read -r val
a\\b
c:~$ echo $val
a\\b

This may be a bit late, but why do you need to have input that includes special characters like this? (Just seems to be asking for trouble.....)
