This one is easy.
You simply forgot the backslash in your link procedure. It must be:
g++ -o test_file -I/$ROOTSYS/include -L/$ROOTSYS/lib \
-lNew -lBase -lFunc -lCint -lClib -lCont -lFunc -lHist -lHtml -lMatrix \
-lMeta -lMinuit -lNet -lPostscript -lProof -lTree -lUnix -lZip -lGpad \
-lGui -lGraf -lGraf3d -lGX11 -lX3d -lXm -lXpm test_root.C
