Purpose of This Assignment:

Purpose of this assignment is to teach you about shell scripts with if

structure.

Write a shell script which performs the following tasks:

Your script should check whether the two files "names" and

"surnames" exist. If either one of them does not exist, your script

should abort with an appropriate error message.

Your script should check whether the number of lines in these files

are equal. You can use the $"$wc$"$ command with appropriate

parameters to obtain the number of lines in a file.

Assume each line in file "names" contains a name, and each line in

"surnames" contains a surname. If the number of names and

surnames do not match; print which file has missing entries, and

how many. Then, if the number of names is greater than

surnames, print all names without a surname; otherwise print all

surnames which do not have a name. Print an appropriate

message if the number of lines in both files are equal.

Example:

Names

Ali

Ayse

Ipek

Veli

Output:

There are $2$ missing surnames.

The names without a surname:

Ipek

Veli

Surnames

Atak

Tutak
