The "/" character is a part of the substitute command of sed, as well as that of your data, which is why sed balks.

Try something like:

sed 's#export mib =/opt/old_mib/#export mib = /opt/new_mibs/#'

Otherwise, escape each "/" character in your search and replacement strings.

You would use a \ to escape a special character such as a / You'd put this before the special character. So you would escape it like this:

\/

Or

sed 's|export=/opt/old_mib/|export=/opt/new_mibs/|g'
