Use Variables with Scripts

Using an editor or the cat command, write a script that uses a variable. Note that this script uses the bash shell on LINUX, but you can also use the ksh shell with UNIX.


1) Set a value for the variable first using typeset then check it using set.

[root@vmpc_rh804 root]# typeset first=you
[root@vmpc_rh804 root]# set | more
BASH=/bin/bash
BASH_ENV=/root/.bashrc
BASH_VERSINFO=([0]="2" [1]="05b" [2]="0" [3]="1" [4]="release" [5]="i686-pc-linu
x-gnu")
BASH_VERSION='2.05b.0(1)-release'
COLORS=/etc/DIR_COLORS
.
.
.
first=you
hi=hello
langfile=/root/.i18n


2) Write a short Welcome script that uses a variable.

[root@vmpc_rh804 root]# cat > Welcome.bash
#!/bin/bash
#
first=Student
echo "Welcome to Linux $first"
Ctrl/D


3) Execute your script using the shell interpreter.

$ bash Welcome.bash
Welcome to Linux Student
