Question

But, the program do not recognize the for instruction and generates only one output, corresponding to the first program. Neither the echo instructions.
What is the problem? I am working on MacOS X 10.6.8 and i tried execute on Terminal and X11, and isn´t chmod problem…

#The code for count perl execution time, for each archive in Prueba Folder. 

#!/bin/bash

FILES= ~/Desktop/ncRNA/Prueba/*

for f in $FILES
do
START =$(date +%s)
echo "Processing $f file..."
perl $f
END =$(date +%s)
DIFF=$(( $END - $START ))
echo "It took $DIFF seconds"
date
echo "It was completed"

done

exit

The output:

¿Cual fue el tiempo de caida libre?
42
Si el tiempo de caida libre fue de : 42 segundos, entonces
La velocidad en caida libre fue de 412.02 m/s^2

The problem is that you have space character before and after the equal sign. Omit any spaces before and after the equal sign when you set a variable.

Also put double quotes around the variables which may contains spaces or reserved characters. –> "$f" instead of $f

#!/bin/bash
FILES=~/Desktop/dossiereee/*
for f in $FILES
do
    START=$(date +%s)
    echo "Processing $f file..."
    perl "$f"
    END=$(date +%s)
    DIFF=$(( $END - $START ))
    echo "It took $DIFF seconds"
    echo "It was completed"
done
