Hello mohtashims,

If you have GNU datein your system then following may help you in same.
Let's say we have following Input_file(as an example).
Code:
ls -ld   Input_file
-rw-rw-r-- 1 Singh_is_King   Singh_is_King  100 Jul 27 10:51  Input_file

Then following is the command for changing the timings.
Code:
touch -t $(date -d"1 week ago" +%y%m%d%H%M)   Input_file

Now after executing above command, when you check the Input_file details they will be as follows.
Code:
ls -ld   Input_file
-rw-rw-r-- 1 Singh_is_King   Singh_is_King  100 Jul 21 06:07  Input_file

Thanks,
R. Singh

This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
