Linux Find Command: Find Files Modified On Specific Date

There are many situations in which we have to find out all files that have been modified on a specific date using find command under Linux.

There are two ways to list files in given directory modified after given date of the current year. The latest version of GNU/find command use the following syntax:

Syntax

GNU/find latest version:
find /path/to/dir -newermt "date" find /path/to/dir -newermt "May 13" find /path/to/dir -newermt "yyyy-mm-dd" ## List all files modified on given date find /path/to/dir -newermt yyyy-mm-dd ! -newermt yyyy-mm-dd -ls ### print all *.sh ### find /path/to/dir -newermt "yyyy-mm-dd" -print -type f -iname "*.sh"

The other way of doing this works on the versions of find before v4.3.3:

touch -t 02010000 /tmp/timestamp
find /usr -newer /tmp/timestamp

then we can remove the reference file:
rm -f /tmp/stamp$$

To find out all Shell Script files (*.sh) in /home/linux/scripts that have been modified on 2013-05-01 (01/May/2013), enter:

find $HOME/scriptss -type f -name "*.sh" -newermt 2013-05-01 ! -newermt 2013-05-02 -print

Pass the -ls option to get detailed file listing:

find $HOME/scriptss -type f -name "*.sh" -newermt 2013-05-01 ! -newermt 2013-05-02 -ls

CentOS / Redhat : Configure CentOS as a Software Router with two interfaces

Linux can be easily configured to share an internet connection using iptables. All you need to have is, two network interface cards as follows: a) Your internal (LAN) network connected via eth0 with static ip address 192.168.0.1 b) Your external WAN) network is connected via eth1 with static ip address 10.10.10.1 ( public IP provided by ISP ) Please note that interface eth1 may have public IP address or IP assigned by ISP. eth1 may be connected to a dedicated DSL / ADSL / WAN / Cable router: Step # 1: Enable Packet Forwarding Login as the root user. Open /etc/sysctl.conf file # vi /etc/sysctl.conf Add the following line to enable packet forwarding for IPv4: net.ipv4.conf.default.forwarding=1 Save and close the file. Restart networking: # service network restart Step # 2: Enable IP masquerading In Linux networking, Network Address Translation (NAT) or Network Masquerading (IP Masquerading) is a technique of transceivin

Virtual Box and Alt/Tab Keys

I use virtual box for all my testing activities. It comes too often that I have a virtual box VM window open & I want to switch to my host machine to see some stuff like tutorials etc.. If you press the alt+tab combination it just works inside the VM & doesn't switches to host machine. In these scenarios you can press the host key once ( not hold it ) & then whatever you press goes to host machine. So in general where host key is the default Right Ctrl, just press Right Ctrl once & now press the alt+tab & it will switch you out to host machine. This is really helpful when you have the VM windows open or you're working on seamless mode. Hope it help others too.

Shell Script: Find Number Of Arguments Passed

Many times , when we create shell scripts we try to do repetitive tasks through functions. Some functions take arguments & we have to check the no. of arguments that are passed to it. Each bash shell function has the following set of shell variables: [a] All function parameters or arguments can be accessed via $1, $2, $3,..., $N . [b] $* or $@ holds all parameters or arguments passed to the function. [c] $# holds the number of positional parameters passed to the function. [d] An array variable called FUNCNAME ontains the names of all shell functions currently in the execution call stack. Example Create a shell script as follows: #!/bin/bash # Purpose: Demo bash function # ----------------------------- ## Define a function called test() test(){ echo "Function name: ${FUNCNAME}" echo "The number of positional parameter : $#" echo "All parameters or arguments passed to the function: '$@'" e
