use concat combine word epochtime.you can epochtime using tounixtime()

a = load 'words.txt' (word:chararray); b = foreach generate concat(concat(a.word,'_'),(chararray)tounixtime(currenttime()); dump b; 

let's shell script names test.sh

%declare my_shell_script 'test.sh' = load 'data.txt' (f1:int,f2:chararray); b = foreach generate '$my_shell_script'; 

if shell script has parameter param1

%declare my_shell_script 'test.sh $param1' = load 'data.txt' (f1:int,f2:chararray); b = foreach generate '$my_shell_script';
