How to use backslash and variables in sed
I have a line that contains backslashes in which I want sed to substitute text with variables.
The line;
\\s008\2033330user$
I want to change this in \\s008.ourschool.com\2033330user$
I now use this script:
USER=2033330user
sed 's/\\'"$USER"'/.ourschool.com\\'"$USER/"
This doesn't seem te work for me. What am I doing wrong?

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
