 find . -type f -printf '%T@ %p\n' | sort -n | tail -1

this return me the next:

1376221215.000000000 ./Rev.12345/run.exe

I want to get only the 12345 number. Which command I should use (I try to use cut command, without success)?

Answer 1

You can pipe the output to sed:

... | sed 's/.*Rev\.\([0-9]*\).*/\1/'

Answer 2

You can pipe the output with:

awk -F '[./]+' '{print $4}'
