issue with "/" and "." characters in sed

I have little problem when I try pass a variable (which contain a path) to sed. It work well if variable didn't contain "/" character. simple code from script for example:

sed "$1/d" $conf

file $conf contain next lines

aaa 
/bbb  
.ccc

When I try put:

scriptName aaa

all work well. But if i put 

scriptName /bbb

I got

sed: can't find label for jump to `bb"/d

message. Also I try

scriptName \/bbb
scriptName //bbb

Last falls with

sed: -e expression #1, char 9: unknown command: `/'

How work with sed is I take path from variable and it contain special characters?

There are two ways to work around the issue:

Escape the / in your pattern:

sed '/\/bbb/d' filename

Supply a different delimiter, but the delimiter would need to be escaped (not the / in the pattern):

sed '\#/bbb#d' filename
