Question

Part 1:

Create a shell script that returns a full name associated with a userid specified in the command line argument.

• Use the names found in /acct/common/CSCE215-Spring19.

• Your shell script should be named “findName.sh”

– Example usage:

$ ./findName.sh seiei

SETSUNA F SEIEI

$

– Your shell script must either:

Return the full name associated with the userid

or

Return an error message if the command line arguments are not equal to 1.

or

Return the message “Sorry that person is not in CSCE215 this semester” No other

output is acceptable.

Part 2: findName program (8 points)

1. Create a C++ program that takes a command line argument value (userid) and passes this argument

to a shell script. HINT: system()

2. As in the previous assignment, modify your makefile to include a rule that creates a backup of

the source files, makefile, and readme in an archive directory in your home directory structure. Submit

an uncompressed tar file named $USER.findname.tar with your modified source code files only. (ie

yourUserid.findname.tar)

Be sure to document your code in a README file.

• In order to obtain credit for your project your submission must react properly to the following

commands:

$ tar xvf $USER.findname.tar

$ make

$ ./findName someuserid

$

3. Your program will be graded based on it’s ability to execute the above commands and return one of 3

allowable outputs:

• first lastname, or

• some error message based on an incorrect number of command line arguments, or

• the message stating that the user is not in CSCE215 this semester

Answer 1

Part-1 Solution:

Filename: findname.sh

#!/bin/bash
# findName.sh
searchFile="/acct/commmon/CSCE215-Spring19"

if [[ $1 = "" ]] ; then
  echo "You need to supply an argument to the script. Please rerun the script. syntax is below."
  echo "./`basename $0` SETSUNA F SEIEI"
  exit 2
fi

grep -i $1 ${searchFile}
if [[ $? = "1" ]] ; then
  echo "$1 was not found in ${searchFile}"
fi

The above shell script returns a full name associated with a userid specified in the command line argument.
