Linux Command History with date and time

I wants to check on my linux system when which command was fired - at which date and time.

I fired commands like this:

history 50 

It shows me the last 50 commands history, but not with date and time at which it was fired. Does any one knows how to do it?

Regarding this link you can make the first solution provided by krzyk permanent by executing:

echo 'export HISTTIMEFORMAT="%d/%m/%y %T "' >> ~/.bash_profile
source ~/.bash_profile

Try this:

> HISTTIMEFORMAT="%d/%m/%y %T "

> history

You can adjust the format to your liking, of course.

In case you are using zsh you can use for example the -E or -i switch:

history -E

If you do a man zshoptions or man zshbuiltins you can find out more information about these switches as well as other info related to history:

Also when listing,
 -d     prints timestamps for each event
 -f     prints full time-date stamps in the US `MM/DD/YY hh:mm' format
 -E     prints full time-date stamps in the European `dd.mm.yyyy hh:mm' format
 -i     prints full time-date stamps in ISO8601 `yyyy-mm-dd hh:mm' format
 -t fmt prints time and date stamps in the given format; fmt is formatted with the strftime function with the zsh extensions  described  for  the  %D{string} prompt format in the section EXPANSION OF PROMPT SEQUENCES in zshmisc(1).  The resulting formatted string must be no more than 256 characters or will not be printed
 -D     prints elapsed times; may be combined with one of the options above

It depends on the shell (and its configuration) in standard bash only the command is stored without the date and time (check .bash_history if there is any timestamp there).

To have bash store the timestamp you need to set HISTTIMEFORMAT before executing the commands, e.g. in .bashrc or .bash_profile. This will cause bash to store the timestamps in .bash_history (see the entries starting with #).

HISTTIMEFORMAT="%d/%m/%y %H:%M "

For any commands typed prior to this, it will not help since they will just get a default time of when you turned history on, but it will log the time of any further commands after this.

If you want it to log history for permanent, you should put the following line in your ~/.bashrc

export HISTTIMEFORMAT="%d/%m/%y %H:%M "
