Exp. No. 4 Vowel or Consonant Shell Programming
Aim
To write simple shell scripts using shell programming fundamentals.
The activities of a shell are not restricted to command interpretation alone. The shell
also has rudimentary programming features. Shell programs are stored in a file (with
extension .sh). Shell programs run in interpretive mode. The original UNIX came with the
Bourne shell (sh) and it is universal even today. C shell (csh) and Korn shell (ksh) are also
widely used. Linux offers Bash shell (bash) as a superior alternative to Bourne shell.
