You actually need 3 slashes.

Code:
lava@host$ cat file
one,ABCD\XYZ,Server One
lava@host$
lava@host$ cat run
#!/bin/ksh

VAR="ABCD\\\XYZ"

echo "Var is $VAR"
sed -e 's/'$VAR'/SERVER/' file
lava@host$
lava@host$ ./run
Var is ABCD\XYZ
one,SERVER,Server One

Cheers

But, i need to get the value into VAR from another var ENVDB

Code:
 
$  echo $ENVDB
ABCD\XYZ
$ VAR=`echo "$ENVDB" | sed "s/\\/\\\\/"`
sed: command garbled: s/\/\/

Any idea, how to put the value from ENVDB to VAR?

(The number of backslashes will be different when typed from the command prompt compared with a similar line in a script. It is important that the solutions posted are tested from a script not from the command line.).

Its working from command line, But when i run it from a script not working

Code:
$ cat file
one,ABCD\XYZ,Server One
$ cat run
#!/usr/bin/ksh
ENVDB='ABCD\XYZ'
VAR=`echo $ENVDB | sed 's/\\/\\\\/'`
sed "s/$VAR/SERVER/" file
$ run
sed: command garbled: s/\/\\/

For me it worked when i use 4 '\' in side script

Code:
VAR=$(echo $ENVDB | sed 's/\\\\/\\\\\\\\/')
