Scripting

[unrevealed01]

Hi guys I'm new to scripting in Linux but I need a help urgently. I need to know how to delay a command execution? for example a delay of 10 seconds before a command line is executed! I need this help very urgently.. I would appreciate any notes or even commands that would help me


Thanks guys

The sleep command, e.g.:

$ sleep 5

delays 5 seconds the next sentence.

does it work with .sh files?

Guys.. after checking here is the code. Could you guys check whether there is any problem with my script as the execution of the command has some problem.

#!/bin/bash

#for stress test in `seq 10`
do
echo "Running the stress test now";
read -p "Entering S3 mode now. Press ENTER once ready";
echo -n "mem">/sys/power/state;
echo "Wake up from S3 is successful";

sleep 10;

read -p "Entering S1 mode now. Press ENTER once ready";
echo -n "standby">/sys/power/state;
echo "Wake up from S1 is successful";
echo "Looping back";
done;
exit 0;



thank you guys for the help

Do it yourself.
Test your script with "-xv" option in the shabang or try this while executing your script:

$ bash -xv <your_script_name>

You should test your codes and scripts and post the problems here.

thank you guys for the help
