# nohup sh dunning_script_normal.sh > log.out &

# -> running script as root
nohup -> keep running the script even when I log out
sh -> run shell script
dunning_script_normal.sh -> the actual script file
> -> redirect output
log.out -> output will be stored in log.out file
& -> release shell prompt when I run the script

This depends on what linux you are using. For debian like distros start here:

and for redhat like distros start here:

Hi, removing file by rm command does not delete the file from a filesystem. To get rid of this file almost completely a shred linux command can be used.

shred command: DESCRIPTION
Overwrite the specified FILE(s) repeatedly, in order to make it harder for even very expensive hardware probing to recover the data.

usage:

shred myfile.txt
other tools:
srm - secure remove (secure_deletion toolkit)
sfill - secure free disk and inode space wiper (secure_deletion toolkit)
smem - secure memory wiper (secure_deletion toolkit)
sswap - secure swap wiper (secure_deletion toolkit)

Hi Ashar,

fist you need to identify your usb device by lsusb command. The next step would be to check if your device is supported by ubuntu. Here is the list:
