Hey There,

With the variable assignment, you've got another level of escaping to do, and, admittedly, it can get confusing

Sometimes a good idea is to use a substitute character for the delimiter (like %, so you would write sed 's%this%that%') to reduce confusion.

In any event, this should do it for you

Quote:

-bash-3.2$ echo $path | sed 's/\//\/\\/g'
/\home/\xyz/\abc
-bash-3.2$ somepath=`echo $path | sed 's/\\//\\/\\\/g'`
-bash-3.2$ echo $somepath
/\home/\xyz/\abc

Best wishes,

Mike

Code:

somepath=$(echo $path | sed 's/\//\/\\/g')

works as expected ...
