Top Forums Shell Programming and Scripting How to compare if the size of the directory is more than 500MB in unix Post 302597968 by shaal89 on Monday 13th of February 2012 02:12:53 AM

actually..

Code:
size=`du -sh`
size=`echo $size | sed 's/.$//'`
size1='30'
if [ $size -gt $size1 ]
then
  echo "size greater"
else
  echo "size smaller"
fi

This doesnt work for me..
After i change the script to
Code:
size=`du -sm`
size=`echo $size | sed 's/.$//'`
size1='30'
if [ $size -gt $size1 ]
then
  echo "size greater"
else
  echo "size smaller"
fi

We are removing only that '.' right.. we are not removing M or G

NAME
l2ping - Send L2CAP echo request and receive answer SYNOPSIS
l2ping [-i <hciX>] [-s size] [-c count] [-t timeout] [-d delay] [-f] [-r] [-v] bd_addr DESCRIPTION
L2ping sends a L2CAP echo request to the Bluetooth MAC address bd_addr given in dotted hex notation. OPTIONS
-i <hciX> The command is applied to device hciX , which must be the name of an installed Bluetooth device (X = 0, 1, 2, ...) If not speci- fied, the command will be sent to the first available Bluetooth device. -s size The size of the data packets to be sent. -c count Send count number of packets then exit. -t timeout Wait timeout seconds for the response. -d delay Wait delay seconds between pings. -f Kind of flood ping. Use with care! It reduces the delay time between packets to 0. -r Reverse ping (gnip?). Send echo response instead of echo request. -v Verify response payload is identical to request payload. It is not required for remote stacks to return the request payload, but most stacks do (including Bluez). bd_addr The Bluetooth MAC address to be pinged in dotted hex notation like 01:02:03:ab:cd:ef or 01:EF:cd:aB:02:03 AUTHORS
