The way I understood is that you want to be in a loop where there is a main file that keeps having records inserted into it and
when it reaches 50Mb, you want to copy into another file, then empty the main file.

You decide:
Code:
#!/bin/ksh
typeset -i mLastLine mSize
mSize=$(wc -c < xxx)
if [[ ${mSize} -ge 50000000 ]]; then
  cp xxx xxx_50k
  mLastLine=$(wc -l < xxx_50k)+1
  tail +${mLastLine} xxx > xxx
fi
