2. Append Line using Regular Expression/Pattern

This will append the line after the line where pattern match is found. 

Syntax:

sed '/PATTERN/ a <LINE-TO-BE-ADDED>' FILE.txt


sed -e '/#include/ i #ifndef __CINT__' -e '/#include/ a #endif' ./tpc/tsspars/tsspar.y2018.C
sed -i.BAK -e '/#include/ i #ifndef __CINT__' -e '/#include/ a #endif' ./tpc/tsspars/tsspar.y2018.C

foreach f (`find StarDb -name "*.C"`)
  grep '#include "tables/'  ${f}
  if (! $?) then
    echo "file: ${f}"
    sed -i.BAK -e '/#include/ i #ifndef __CINT__' -e '/#include/ a #endif' ${f}
  endif
end
