UNIX/LINUX QUESTIONS. Please solutions only. Thanks!

1. In Linux, the PATH (Sobell, page 308) keyword variable specifies the directories in the order bash should search them when it searches for a script or program you run from the command line. In BASH, what would be the value of your PATH variable? What happens when you put the statement echo $PATH in the BASH function created in previous question.

2. What will the BASH script below do when it runs? Try to describe each line of the code shown below in simple or plain English to demonstrate your understanding of the code.

#!/bin/bash

question15() {

arg1=$1

arg2=$2

ls if [ $# -gt 0 ]; then clear if [[ -f $1 && -w $1 ]]; then echo The file $1 is readable cp $1 $2.bak echo The backup file created f $2.bak is a copy of $1 file. else echo The file $1 does not exist or is not writable file fi fi }

question15 hello hello

3. Develop simple HTML page that creates a web interface for the BASH script above (question 2)
