Replace string works on command-line but fails when run from shell script
I wish to replace "\\n" with a single white space.

The below does the job on command-line:

Code:
$ echo '/fin/app/scripts\\n/fin/app/01/sql' | sed -e 's#\\\\n# #g';
/fin/app/scripts /fin/app/01/sql

However, when i have the same code to a shell script it is not able to get me the same output: See below:

Code:
$ more check.sh
str=`echo "$1" | sed -e 's#\\\\n# #g'`
echo $str>check.now

Code:
$ bash -x ./check.sh '/fin/app/01/scripts\\n/fin/app/01/sql'
++ echo '/fin/app/01/scripts\\n/fin/app/01/sql'
++ sed -e 's#\\n# #g'
+ str='/fin/app/01/scripts\ /fin/app/01/sql'
+ echo '/fin/app/01/scripts\' /fin/app/01/sql

Code:
$ more check.now 
/fin/app/01/scripts\ /fin/app/01/INFENG/sql

We see the issue with "/fin/app/01/scripts\" the trailing \ at the end of the first string.

Note: I have to pass the argument to check.sh script strictly in single quotes only.

Requesting suggestions and explanations for this issue.
