I tried this so far (the line after variable= should be replaced with /tmp/anything):

sed -e "/^variable=/s/=.*$/=\/tmp\/anything\//" filename

this works.

But I can't make it when I replace /tmp/anything with $var2

Something like this?

Code:
 sed 's_\(variable=\).*_\1'$var2'_'

sed 's_\(variable=\).*_\1'$A'_' filename

sed: command garbled: s_\(variable=\).*_\1/tmp/anything_


moreover, I prefer to use sed -e since I have several other subsitutions and I want to add this also.

thx
