basename and dirname

basename

basename is a command used to get the filename or the leaf directory name from a path given. basically it will select the last string which is prefixed by /.

For example:

>basename /x/y/z/abc.txt
abc.txt

The above command will bring output as abc.txt

>basename /x/y/z/
z

It will bring z as output

Please note , inside a script if we use basename $0 , it will bring the name of the script. It has many uses.

dirname

dirname will bring the path of the directory. ie the prefix for / for a leave directory name or file.

For example:

>dirname /x/y/z/abc.txt
/x/y/z

The above command will bring output as /x/y/z

>dirname /x/y/z/
/x/y

It will bring /x/y as output

UNIX : What is /dev/null ?

/dev/null is a file where you can discard the output of the command executed. This file is also called as Bit Bucket. eg : >ls -ltr > /dev/null > Here the output of command ls is never shown on terminal STDOUT. It is redirected to bit bucket. Sometimes we need not display the output as well as error message of command.In this case use the following command. > command > /dev/null 2>&1 The command output is redirected to /dev/null.Also the error output, STDERR (which is called by 2) is redirected to STDOUT (called as 1 ).That means the error will be redirected to /dev/null.
