Linux good old command to check IP Address is  ifconfig which works probably in all distro. There is already new implementation on how to check the IP Address via command line from some distro. Some distro now supports the command, ip addr show which also displays the IP Address. The ifconfig command has a long output, which is quite scary if you are new to Linux. To filter the desired output in ifconfig, awk or gawk will come to the rescue. Below are some examples on how to do it: Display only the IP Address: ifconfig -a | awk 'NR==2' Sample Output: inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0 Display only the MAC Address: ifconfig -a | awk 'NR==1' Sample Output: eth0  Link encap:Ethernet  HWaddr 07:00:16:f1:bb:ac HWaddr is the MAC Address Display both IP and MAC Address: ifconfig -a | awk 'NR==1,NR==2' Using awk command ifconfig output is displayed line by line.

Command below will delete all text (".txt") files on the specified path.      Del D:\txtlog\*.txt Command above will delete all files with ".txt" extension in d:\txtlog directory. Easy enough to delete all matching files. Using the same method with rmdir or rd command this will not work. For example, if we have a directory on d drive that is auto-generated by an application and the filename is consistent with a pattern plus incrementing number at the end to differentiate the folder from other folders.    D:\baklogs\log1\    D:\baklogs\log2\    D:\baklogs\log3\    Etc..    D:\baklogs\log100\ The folder name has a consistent pattern that is preceded by the word “log” plus incrementing number. If the command below is executed to remove the directories in one go, an error is shown which h...
