it smells like "homework" spirit..even though, here is the answer of all your questions..click

Why ASAP?!? This smells as homework... anyway go through the find and stat commands.

parasdua · 04-22-2008, 08:03 AM

would the following b ok?

for modified time:

ls -lart --full-time

for last accesed time:

ls -laru --full-time

Also how can i do it using pipes?

laucian · 04-22-2008, 08:11 AM

ok i think you need some starter help..

1.
pipes in linux are the commands that you add to each other like a chain...for example, using ps -ef you can list all your running processes und with grep init you can select the lines including init in them..piping them is just combining them

Code:

ps -ef | grep init

2.you need to get familiar with bash scripting..
there are good tutorials on internet..here is one them
http://www.linuxconfig.org/Bash_scripting_Tutorial

just forget your homework for some time, and read this tutorial(which will also give you some ideas about using the pipes)

then start typing your code..if you have problems then paste your code here and ask questions..but do not expect an whole code from someone else..

i hope this one helps a bit

Hi Parasdua

just tried to write a script similar to your requirement.

Code:

#!/bin/bash
#Author: K.Sridhar
#mod_acc.sh: script to find last modified and last accessed time of a file
E_NOARG=65
E_MOREARG=66
if [  $# = 0 ]
then
        echo -e '\E[31m' "Usage: $0 <filename>"
        tput sgr0
        exit $E_NOARG
elif [ $# -gt 1 ]
then
        echo -e '\E[31m' "Please give only one file at a time"
        tput sgr0
        exit $E_MOREARG
fi
LS=`which ls`
MOD_TIME=`$LS -lart $1|cut -f6,7,8 -d" "`
ACC_TIME=`$LS -laru $1|cut -f6,7,8 -d" "`
echo "The modified time of the file is $MOD_TIME"
echo "The accessed time of the file is $ACC_TIME"

Thanks
