How to look up a file in a directory? (UNIX)

In the below example:
CCY_EMU_EXT = filename (it will look up files CCY_EMU_EXT and more CCY_EMU_EXTx, where x can be anything with unlimited number of characters)

After the ">" symbol is the path where you want the result to print it to.  CCY_EMU_EXT_1.log is the result file.

find /gtsallsrv/gts/ -name "*" | xargs grep -l CCY_EMU_EXT  > /var/tmp/v439333/CCY_EMU_EXT_1.log &
