Lets say I have below two variables.

Code:
!#/bin/bash
MEMFILE=lock-file

date +%s > $MEMFILE

sleep 130

UPTIME= `date +%s`
I want to take the output of ( $UPTIME - $MEMFILE) in minutes and seconds.

Eg:

"Total downtime was 2 minutes and 5 seconds"

Please help me...

It's a little easier to work with command substitution is you use $( ... ) instead of backticks. You can do arithmetic in the shell using $(( ... )) and can use addition, subtraction, multiplication, division, exponents, and modulus.

Here is a variant of your script set to do the first part of the calculation to get seconds, in preparation for then calculating the minutes.

Code:
#!/bin/sh

memfile=lock-file

date +%s > $memfile

sleep 130

then=$(head -n 1 $memfile)
now=$(date +%s)

downtime=$(( $now - $then ))

seconds=$(( $downtime % 60 ));

echo Downtime was X minutes and $seconds seconds
Can you see how to modify it to get minutes?

Hello Turbocapitalist,

Yeah.. I got it.


Minutes=$(( $downtime / 60 ));

Thanks a lot for your support. and for everyone who have supported me out...
