I tried with below mentioned code and executing script in current dir it's not working .

#!bin/bash
find $HOME -type f | ls file
 while read file 
 do
    echo $file;
    sed -i 's/ admin$/unixadmin/ /g'  $file
    sed -i 's/ date$/`date +_%m_%d_%y_%H_%M`/ /g' $file
 done

Not sure what's not working, but try to remove the " /" in front of the g . sed needs the command to read like s/.../.../g
