Answer by lessthanideal for bash/fish command to print absolute path to a file

The find command may help

find $PWD -name ex*
find $PWD -name example.log

Lists all the files in or below the current directory with names matching the pattern. You can simplify it if you will only get a few results (e.g. directory near bottom of tree containing few files), just

find $PWD

I use this on Solaris 10, which doesn't have the other utilities mentioned.
