Question

The trouble is, after runn

Answer 1

Use double quotes instead of single quotes. Single quotes would prevent variable expansion.

/usr/local/bin/sed -i -e "s/${String1}/${String1R}/g;s/\/${String2}\//\/${TString2R}\//g" ${ROOT_DIR}/data/file.sql

Moreover, it seems that your variables are path strings which might contain forward slashes, i.e. /. In that event use a different separator:

"s|${String1}|${String1R}|g"

Using a different separator would obviate the need of escaping / in the pattern and replacement.
