I am looking for a command in bash to change the last modified and created timestamp to be changed to present time.
How do I do it using shell command/script?
Thanks!
touch will update the access and modification times (or only one of the two with -a or -m respectively).

Any possibility to changes user wise time zone in Linux.
Which user (a web client, or someone remotely logged thru ssh)? He could set the TZ environment variable, perhaps by adding a line like
export TZ='Europe/Paris'
in his ~/.bashrc file if bash is his login shell.
See environ(7) and tzselect(8)

How can I block someone from spamming by console using the "write" command in unix.
Run the command mesg n. Preferably, add it to your .bashrc or equivalent so it runs when you start up.
In your console, type:
mesg n
For more information, read the manual pages (man mesg).

I'm running Linux Mint 14 and accidentally replaced the contents of /etc/environment file. It was originally something like:
PATH=/usr/bin
but with some extra stuff. At the moment, most commands don't work in the terminal. If I do "ls", I get "command not found". Does anyone know the standard contents of this file is?
On ubuntu 12.04 it is:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

I just uninstalled a program (ros) from my computer (ubuntu) using the ubuntu software center.
However, since this moment, whenever I open a shell, I get the following message:
bash: /opt/ros/groovy/setup.bash: No such file or directory
Did I do anything wrong?
Have a look at ~/.bash_profile
