Sorry, I deleted my previous post. On OS X the default behaviour of Bash is to store the epoch in the history file for each command run, which you can then use HISTTIMEFORMAT to format the output timestamp when using the history command. On Linux (RHEL) this is not the default and I can't quite find where to set it. But if it's not set already, you have no chance of getting the information you want from that time period.
If you see something like the following (#<number), you might be OK, providing your HISTSIZE is long enough and no one has truncated the history file since the date you want:
Hi,
I can use history command in unix to view my last 50 commands. But how can I run the previous commands easily? Can history command help?

Hello All,
I was wondering if anyone knew of a way to find out what commands were run on a specific date.
I'm looking to see if I can find certain commands that were run on 3/4, today is 3/10...?
Any thoughts or ideas would be much appreciated!
Thanks in Advance,
Matt

hi, i have an AIX6.1 machine and i modified a user's profile so that it creates history file for each ip address that connects with this user. the reason i did this is because more than 1 person connects with the same user so i want to keep track of command run by all of them. therefore, in the...

mkfs
MKFS(8) System Administration MKFS(8)NAME
mkfs - build a Linux filesystem
SYNOPSIS SYNOPSIS
mkfs [options] [-t type fs-options] device [size]
DESCRIPTION
mkfs is used to build a Linux filesystem on a device, usually a hard disk partition. The device argument is either the device name (e.g.
/dev/hda1, /dev/sdb2), or a regular file that shall contain the filesystem. The size argument is the number of blocks to be used for the
filesystem.
The exit code returned by mkfs is 0 on success and 1 on failure.
In actuality, mkfs is simply a front-end for the various filesystem builders (mkfs.fstype) available under Linux. The filesystem-specific
builder is searched for in a number of directories, like perhaps /sbin, /sbin/fs, /sbin/fs.d, /etc/fs, /etc (the precise list is defined at
compile time but at least contains /sbin and /sbin/fs), and finally in the directories listed in the PATH environment variable. Please see
the filesystem-specific builder manual pages for further details.
OPTIONS -t, --type type
Specify the type of filesystem to be built. If not specified, the default filesystem type (currently ext2) is used.
fs-options
Filesystem-specific options to be passed to the real filesystem builder. Although not guaranteed, the following options are sup-
ported by most filesystem builders.
-V, --verbose
Produce verbose output, including all filesystem-specific commands that are executed. Specifying this option more than once
inhibits execution of any filesystem-specific commands. This is really only useful for testing.
-V, --version
Display version information and exit. (Option -V will display version information only when it is the only parameter, otherwise it
will work as --verbose.)
-h, --help
Display help and exit.
BUGS
All generic options must precede and not be combined with filesystem-specific options. Some filesystem-specific programs do not support
the -V (verbose) option, nor return meaningful exit codes. Also, some filesystem-specific programs do not automatically detect the device
size and require the size parameter to be specified.
